Abstract

A medical fluid injecting device includes an injection control unit which controls the operation of a syringe drive mechanism according to preset injection control data to perform medical fluid injection. Before the medical injection, a data input unit acquires kidney function data on a subject to be imaged, and a control setting unit generates the injection control data corresponding to the acquired kidney function data and sets the injection control data in the injection control unit. Therefore, the operation of medical fluid injection corresponding to the kidney function of the subject can be best controlled. Consequently, injection of a medical fluid such as a contrast medium into the subject having renal failure in the same way as that of subjects to be imaged having normal renal function can be simply and infallibly prevented.

Chemical injection device, fluoroscopic imaging system having this chemical injection device, computer program of chemical injection device, and data processing method

The present invention relates to a chemical injection device that performs chemical injection from a chemical syringe on a subject to be imaged with fluoroscopic image data, a fluoroscopic imaging system having the chemical injection device, a computer program for the chemical injection device, and a data processing method.

At present, CT (Computed Tomography) scanner, MRI (Magnetic Resonance Imaging) apparatus, PET (Positron Emission Tomography) apparatus, ultrasound diagnostic apparatus, etc. There is. Further, as a fluoroscopic imaging apparatus that captures a blood vessel image that is fluoroscopic image data of an imaging subject, there are a CT angio apparatus, an MRA (MR Angio) apparatus, and the like.

When using the fluoroscopic imaging apparatus as described above, a chemical solution injection such as a contrast medium or physiological saline may be performed on the imaging subject, and a chemical solution injection device that automatically executes this injection is also in practical use. A general chemical solution injection device holds a chemical solution syringe filled with an injected chemical solution, and presses a piston member into the cylinder member, thereby injecting a chemical solution into an imaging subject.

Although the fluoroscopic imaging device functions as a stand-alone, normally, a fluoroscopic imaging system including a part of the fluoroscopic imaging device is constructed. Such a fluoroscopic imaging system includes, for example, a chart management device, an imaging management device, a fluoroscopic imaging device, a data storage device, an image browsing device, and the like.

The medical chart management device is generally called HIS (Hospital Information System) or the like, and manages a so-called subject electronic medical chart. This subject electronic medical record is created for each imaging subject.

For example, when fluoroscopic image data is captured from a certain imaging subject, imaging order data is created by the medical chart management device based on the subject's electronic medical record of the imaging subject. This imaging order data is generated for each imaging operation in which fluoroscopic image data is imaged from the imaging subject.

More specifically, the imaging order data includes, for example, imaging work ID (IDentity) that is unique identification information, identification information of the fluoroscopic imaging device, imaging subject ID, imaging start and end dates and times, and the like.

Such imaging order data is supplied from the HIS to the imaging management device. The imaging management apparatus is generally called RIS (Radiology Information System) or the like, and stores imaging order data for imaging fluoroscopic image data from an imaging subject.

The fluoroscopic imaging apparatus acquires imaging order data from the RIS and executes an imaging operation. In that case, in the fluoroscopic imaging apparatus, fluoroscopic image data is captured from the imaging subject corresponding to the imaging order data. The fluoroscopic image data is output with at least a part of the imaging order data by the fluoroscopic imaging device to the data storage device.

This data storage device is generally called a PACS (Picture Archive and Communication System) or the like, and stores fluoroscopic image data to which imaging order data is added.

An image browsing device generally called a viewer is connected to the PACS. For example, the image browsing apparatus reads the fluoroscopic image data using the imaging order data as a search key, and displays the fluoroscopic image data.

There are various proposals for the fluoroscopic imaging system as described above (see, for example, Patent Documents 1 and 2).

Further, as shown in FIG. 6, the syringe drive mechanism 412 drives the chemical syringe 800 on which the RFID chip 810 on which the chemical condition data is recorded is mounted. Therefore, as shown in FIG. 1, the data input unit 422 acquires chemical solution condition data from the RFID chip 810 by the RFID reader 416.

Therefore, the control setting unit 423 generates injection control data corresponding to the chemical condition data. In that case, the control setting unit 423 generates injection control data in which the total injection amount of the chemical solution injection is adjusted according to the renal function data.

Such injection control data includes, for example, protocol data in which the operating stroke and operating pressure of the syringe drive mechanism 412 are set by a predetermined command or the like for each elapsed time.

As described above, the syringe drive mechanism 412 also injects physiological saline as an injecting drug solution together with the contrast medium. Therefore, the injection control unit 421 generates contrast agent injection control data corresponding to the renal function data.

The site input unit 448 accepts an input operation for selecting an imaging site image-outputted by the site display unit 447 as an input operation for one injection control data.

More specifically, in the liquid injector 400, “head, chest, abdomen, legs” are defined as a plurality of body sections, and schematic images corresponding to each of these are registered in the computer unit 405. Yes.

Therefore, when a predetermined operation is performed on the chemical solution injector 400, a schematic image of “head, chest, abdomen, legs” is displayed and output on the upper part of the screen of the touch panel 403 as shown in FIG. The

In addition, in the schematic image of the “head”, which is the above-described body classification, schematic images such as “brain part, jaw part, neck part” and the like are registered as a plurality of imaging parts. Similarly, a schematic image of “chest” is “heart part, lung part”, a schematic image of “abdomen” is “upper abdomen, liver part,...”, And a schematic image of “leg part” is “upper, lower part”. ”And the like are registered in association with each other.

Therefore, when one of the schematic images of the plurality of body ranges displayed and output on the touch panel 403 in the form of a human body is manually operated, the schematic image of the scanner mechanism is displayed and output only above the one schematic image, and is manually operated. Only one schematic image turns bright and the other schematic image turns dark (not shown).

At the same time, schematic images of a plurality of related imaging parts are displayed and output at the bottom. Therefore, when one of the schematic images of the plurality of imaging parts displayed and output is manually operated, as shown in FIG. 9, only the one schematic image is turned bright and the other schematic images are turned dark.

The condition storage unit 441 stores operation condition data of the syringe drive mechanism 412 for each of a large number of imaging parts of the human body. This operating condition data is set, for example, as the total amount of contrast medium injected for each imaging region of the human body.

The operation readout unit 449 reads out the operation condition data corresponding to the imaging region selected by the region input unit 448 from the condition storage unit 441 and sets it in the injection control unit 421 as a part of the injection control data.

The body input unit 451 receives a weight input operation as a human body matter related to the imaging of the fluoroscopic image data, and sets the weight in the injection control unit 421 as part of the injection control data.

More specifically, when the imaging region is selected by manual operation of the schematic image as described above and the operation icon “condition” is manually operated, the weight, total injection amount, injection time, and the like can be input. It becomes a state. Therefore, in such a state, a numerical value of weight is input. Then, as shown in FIG. 10, these are displayed and set as part of the injection control data.

In addition, the chemical injection device 400 generates a history generation unit 427 that generates injection history data including an operation history of the syringe drive mechanism 412 corresponding to the injection control data, and transmits the generated injection history data to the outside to transmit fluoroscopic image data. And a data output unit 428 to be stored together.

The history generation unit 427 also registers at least part of the injection control data, the serum creatinine value acquired from the creatinine measuring device 920, and the body weight acquired from the weight height meter 930 in the injection history data.

Such injection history data includes, for example, image data of a time-dependent graph in which one of the horizontal axis and the vertical axis is the elapsed time and the other is the injection speed, and the injection control data, the imaging subject ID, the injection work ID, etc. It is given by.

As shown in FIG. 3, the control box 500 according to the present embodiment includes a computer unit 501, a communication I / F 502, and the like on which a dedicated computer program is mounted.

Also in the control box 500, the computer unit 501 executes various processes corresponding to the computer program. Therefore, in the control box 500, as shown in FIG. 2, each unit such as the acquisition mediation unit 511 and the history transfer unit 514 is logically realized as various functions.

In response to the acquisition request received from the chemical liquid injector 400, the acquisition mediation unit 511 acquires the imaging order data from the RIS 100, and the chemical liquid injector 400 uses a part of the acquired imaging order data as part of the injection control data. Reply to The history transfer unit 514 receives the injection history data from the chemical solution injection device 400 and transfers it to the PACS 300.

Therefore, the PACS 300 according to the present embodiment not only stores the fluoroscopic image data received from the CT scanner 200 as described above, but also stores the injection history data received from the control box 500 as described above.

As described above, the imaging order data is assigned to the fluoroscopic image data, and the imaging work ID of the imaging order data is assigned to the injection history data. Therefore, the imaging order data and the injection history data are stored in the PACS 300 in a state where they are associated with each other by the imaging work ID.

The image browsing apparatus 600 according to the present embodiment is also a computer apparatus in which a dedicated computer program is installed. As shown in FIG. 3, the image browsing apparatus 600 includes a computer unit 601, a display unit 602, a controller unit 603, a communication I / F 604, and the like.

The image browsing apparatus 600 includes a data reading unit 611 and a data display unit 612 as shown in FIG. 2 when the computer unit 601 executes various processes corresponding to the computer program.

The data reading unit 611 corresponds to, for example, a function in which the computer unit 601 accesses the PACS 300 from the communication I / F 604 corresponding to the computer program and input data to the controller unit 603, and is associated with the imaging work ID. The fluoroscopic image data and the injection history data are read from the PACS 300.

The data display unit 612 corresponds to a function for the computer unit 601 to display the received data of the communication I / F 604 on the display unit 602, and displays the read fluoroscopic image data and injection history data.

Note that there are a plurality of computer programs of the RIS 100 as described above, for example, storing imaging order data in which an imaging work ID, an imaging subject ID, personal condition data, and the like are set, and an input operation of an injection operator. Selecting one of the imaging order data, returning one selected imaging order data in response to an acquisition request received from the CT scanner 200 or the control box 500, and a chemical solution condition received from the control box 500 It is described as software for causing the RIS 100 to transfer data to the HIS 900 and the like.

In addition, the computer program of the CT scanner 200 transmits, for example, an imaging order data acquisition request to the RIS 100 in response to an input operation of the injection operator, receives imaging order data returned from the RIS 100, and receives the imaging order data. The operation of the fluoroscopic imaging unit 201 is controlled in accordance with the imaging order data, the imaging order data is added to the fluoroscopic image data captured by the fluoroscopic imaging unit 201, and the fluoroscopic image data to which the imaging order data is added is transferred to the PACS 300. It is described as software for causing the imaging control unit 210 to execute transmission and the like.

Moreover, the computer program of the chemical injection device 400 acquires the age of the imaging subject based on imaging order data for each imaging operation managed by the RIS 100, and acquires the serum creatinine value of the imaging subject from the creatinine measurement device 920, for example. In addition, the body weight of the imaging subject is obtained from the weight height meter 930, and the estimated value of the glomerular filtration rate is obtained as (140−age) × body weight / 72 × serum creatinine value from the obtained serum creatinine value, age and weight. Calculating, acquiring chemical condition data with the RFID reader 416 from the RFID chip 810 of the chemical syringe 800, generating and setting injection control data from the acquired chemical condition data and the calculated glomerular filtration value, The syringe drive mechanism 412 is moved according to the set injection control data. Control, generating injection history data consisting of the operation history of the syringe drive mechanism 412 corresponding to the injection control data, and transmitting the generated injection history data to the PACS 300 together with the acquired serum creatinine value and body weight. It is described as software for causing the computer unit 405 to store the data together with the data.

Further, the computer program of the control box 500 acquires, for example, the imaging order data from the RIS 100 in response to the acquisition request of the chemical injection device 400, the imaging subject ID of the acquired imaging order data, and the like to the chemical injection device 400. Executing the computer unit 501 for replying, receiving injection history data and chemical condition data from the chemical injection device 400, transferring the received injection history data to the PACS 300 and transferring the chemical condition data to the RIS 100, etc. It is described as software to make it.

Further, the computer program of the PACS 300 receives, for example, the fluoroscopic image data to which the imaging order data is assigned from the CT scanner 200 and stores it, and the injection history data to which the imaging work ID of the imaging order data is assigned as a control box. It is described as software for causing the PACS 300 to execute reception and storage from 500.

Then, for example, the computer program of the image browsing apparatus 600 reads the fluoroscopic image data and the injection history data associated with the imaging work ID from the PACS 300, and displays and outputs the read fluoroscopic image data and the injection history data. This is described as software for causing the computer unit 601 to execute the above.

In the configuration as described above, a method for imaging fluoroscopic image data from an imaging subject using the fluoroscopic imaging system 1000 of the present embodiment will be described in order below. First, the injection operator registers imaging order data in the RIS 100 in advance.

The imaging order data includes, for example, text data such as an imaging work ID, identification information of the CT scanner 200, imaging start and end dates and times, an imaging part, and the like. This imaging order data is usually created based on the subject electronic medical record for each imaging subject.

Therefore, the injection operator who creates the imaging order data manually operates the RIS 100 and acquires the subject electronic medical record from the HIS 900. For this reason, the imaging subject ID, name, weight, and the like are also registered in the imaging order data.

However, in the above-described subject electronic medical record, the body weight, sex, age, serum creatinine value, etc. of the imaging subject are usually registered as personal condition data. For this reason, this personal condition data is also registered in the imaging order data.

However, the imaging order data is composed of various data necessary for imaging work with the CT scanner 200. For this reason, the data which can specify the injection | pouring operation | work of the chemical | medical solution injection apparatus 400 are not included.

When an imaging operation is executed in a state where such imaging order data is registered in the RIS 100, one imaging order data corresponding to the imaging operation is selected by the injection operator manually operating the RIS 100. .

On the other hand, at the site of the imaging work, as shown in FIG. 4, a chemical solution injection device 400 is disposed in the vicinity of the fluoroscopic imaging unit 201 of the CT scanner 200. A chemical syringe 800 is connected to an imaging subject (not shown) located in the fluoroscopic imaging unit 201 with an extension tube, and the chemical syringe 800 is loaded into the injection execution head 410 of the chemical injection device 400.

Next, as shown in FIG. 19, when the injection operator starts the chemical injection device 400 by an input operation of the main operation unit 402 of the injection control unit 401 (step S1-Y), as shown in FIG. A schematic image of a plurality of body sections is displayed and output on the touch panel 403 corresponding to the human body shape (step S2).

In the chemical injection device 400 of the present embodiment, the operation control of the syringe drive mechanism 412 by the injection control data is prohibited in the initial state where the injection control data is not set. And the chemical | medical solution injection apparatus 400 can also set all injection control data manually in the state by which the initial screen was displayed and output as mentioned above, and can also set the one part automatically from imaging order data.

In manual setting (step S3-N), the injection operator presses one of the schematic images of the plurality of body sections displayed and output on the touch panel 403 with the finger. Then, only the schematic image of the selected body section is highlighted and the other schematic images are darkened, and a schematic image of the scanner mechanism is displayed and output above the schematic image of the selected body section.

At the same time, schematic images of a plurality of imaging parts related to the selected body segment are read out below and displayed on the selection screen. Therefore, when the injection operator inputs one of them with a finger or the like, as shown in FIG. 9, only the selected one schematic image is highlighted and the other schematic images are darkened.

When the imaging site is selected as described above, the chemical injection device 400 reads out the operation condition data corresponding to the imaging site and sets it as injection control data. Further, as shown in FIG. 10, the body weight, the injection speed, the total injection amount, the injection time, etc. of the imaging subject are input to the main operation unit 402 as injection control data by the injection operator (step S4-Y).

At this time, in the chemical injection device 400 of the present embodiment, it is also confirmed by the RFID reader 416 whether the RFID chip 810 is mounted on the chemical syringe 800 (step S5-Y).

Therefore, when the RFID chip 810 is mounted on the chemical syringe 800 (step S20-Y), chemical condition data is acquired by the RFID reader 416 (step S6). As described above, this chemical condition data includes various data such as the product name and expiry date related to the filled injection chemical, and various data such as the volume and lot number related to the chemical syringe 800.

Therefore, a part of the chemical condition data acquired in this way is displayed and output on the touch panel 403 of the injection control unit 401 and the head display 415 of the injection execution head 410 as shown in FIG. 14 (step S7). , Audio output.

At this time, on the touch panel 403 and the head display 415, the fact that the displayed chemical solution condition data is acquired from the RFID chip 810 of the chemical syringe 800 is displayed and output by a predetermined logo mark “RFID”.

Therefore, the injection operator confirms the chemical solution condition data that is displayed and output as described above, and inputs the injection control data (step S8-Y). When the setting of the injection control data is completed (steps S9 and S10-Y), the set injection control data and the like are displayed on the touch panel 403 and the head display 415 as shown in FIG. It is ready to operate.

Therefore, when this injection start is input on the touch panel 403 or the like (step S11-Y), the syringe drive mechanism 412 is controlled in response to the set injection control data, so that the subject to be imaged is contrast medium. And saline are infused appropriately.

In addition, in the fluoroscopic imaging system 1000 of the present embodiment, the injection control data can be automatically set in addition to being manually set in the chemical liquid injector 400 as described above. More specifically, as shown in FIG. 8, the chemical injection device 400 of the present embodiment also displays and outputs an operation icon for an acquisition request on the upper left of the initial screen of the injection operation.

Therefore, when the operation icon of the acquisition request is manually operated (step S3-Y), the acquisition request is transmitted to the control box 500 as shown in FIG. The control box 500 transfers the acquisition request received from the chemical liquid injector 400 to the RIS 100.

Then, the RIS 100 returns one imaging order data selected as described above to the control box 500. When receiving the imaging order data from the RIS 100, the control box 500 returns a part of the imaging order data to the drug solution injector 400 as at least a part of the injection condition data.

More specifically, as described above, the imaging order data is based on the imaging work ID, the identification information of the CT scanner 200, the date and time of imaging start and end, the imaging subject ID, the body classification or imaging site, personal condition data, and the like. Become.

Therefore, the control box 500 extracts an imaging work ID, an imaging subject ID, a body classification or an imaging site, personal condition data, and the like from the acquired imaging order data, and returns this to the chemical injection device 400 as injection condition data. .

During communication as described above, as shown in FIG. 11, the chemical liquid injection device 400 displays and outputs guidance data indicating that communication is being performed on the touch panel 403 and the head display 415. For this reason, the user can confirm in real time that the chemical injection device 400 is communicating.

Furthermore, when injection condition data cannot be acquired due to a communication error or the like, guidance data indicating failure in data acquisition is displayed and output on the touch panel 403 and the head display 415 as shown in FIG. For this reason, the user can quickly recognize the failure of data acquisition and execute a retry or the like.

In the chemical injection device 400, the injection condition data acquired from the control box 500 in response to the acquisition request (step S12) is displayed and output on the touch panel 403 and the head display 415 (step S13), and is output as a sound.

At this time, the name and sex of the imaging subject are also displayed and output as injection condition data, so that the injection operator confirms the consistency between the injection condition data and the actual imaging subject.

Further, on the touch panel 403 and the head display 415, the operation icons for setting whether to generate injection control data from the injection condition data are displayed and output together with the injection condition data displayed and output as described above.

Therefore, when the injection control data is generated from the injection condition data confirmed by the injection operator, the “use” operation icon is input. Then, in the drug solution injection device 400 that detects this (step S14-Y), it is determined whether the serum creatinine value and the body weight are set in the injection condition data (steps S15 and S18).

As described above, the serum creatinine value and body weight are usually registered in the electronic medical record, and are also set in the imaging order data acquired as the injection condition data. In that case, the serum creatinine value, body weight, and the like acquired as the injection condition data are also displayed and output on the touch panel 403 and the head display 415.

However, the serum creatinine value and weight may not be set in the imaging order data for reasons such as emergency treatment (steps S15-N and S18-N). In that case, “the serum creatinine value was not set in the imaging order data. Please enter the serum creatinine value.” “The body weight was not set in the imaging order data. A warning guidance (not shown) such as “Please input your weight” is displayed and voiced (steps S16 and S19).

Therefore, the infusion worker confirming this inputs, for example, a serum creatinine value and a body weight by manual operation (not shown). However, in the drug solution injection device 400 of the present embodiment, the serum creatinine value and the body weight can be immediately measured from the imaging subject using the creatinine measurement device 920 and the weight height meter 930, and can be input to the drug solution injection device 400. .

In this case, for example, the infusion operator measures the serum creatinine value from the blood of the imaging subject using the creatinine measuring device 920, and transfers the serum creatinine value to the drug solution infusion device 400 connected by wire. Similarly, the injection operator measures the weight of the subject to be imaged with the weight height meter 930 and transfers the weight to the drug solution injection device 400 connected by wire.

In this way, the chemical injection device 400 in which the serum creatinine value and the body weight are input (steps S17-Y, S20-Y), the RFID chip 810 is mounted on the chemical syringe 800 by the RFID reader 416 as shown in FIG. (Step S21).

Therefore, when the RFID chip 810 is mounted on the chemical syringe 800 (step S21-Y), chemical condition data is acquired by the RFID reader 416 (step S22). As described above, the chemical solution condition data includes various data related to the filled chemical solution and various data related to the chemical syringe 800.

However, the infusate-related data includes, for example, an appropriate type consisting of a work type such as CT or MR, an infusate type such as a contrast agent, an infusate ID consisting of a prefilled syringe product ID, and a contrast agent. Chemical classifications such as components and contrast agents are included.

Therefore, a part of the chemical condition data acquired in this way is displayed and output on the touch panel 403 of the injection control unit 401 and the head display 415 of the injection execution head 410 as shown in FIG. 14 (step S23). , Audio output.

Furthermore, when the chemical condition data is displayed and output on the touch panel 403 and the head display 415 as described above, an operation icon for setting instructions for using or not using the chemical condition data as injection control data is also displayed and output.

Therefore, when using the chemical condition data confirmed by the infusion operator as the infusion control data, the operation operation of “use” is input. Then, the chemical solution injection device 400 that has detected this (step S24), the injection condition data acquired from the imaging order data, the serum creatinine value acquired from the creatinine measurement device 920, the weight acquired from the body height meter 930, the chemical solution Injection control data is generated and set based on the liquid condition data acquired from the syringe 800 (step S25).

At this time, the medicinal solution injection device 400 calculates an estimated value of glomerular filtration value as (140−age) × body weight / 72 × serum creatinine value from the acquired serum creatinine value, age and weight.

When the glomerular filtration rate is calculated in this way, as shown in FIG. 13, the touch panel 403 and the head display 415 display the acquired serum together with the injection condition data such as the personal condition data acquired from the imaging order data. The creatinine value, the acquired body weight, the estimated value of the calculated glomerular filtration value, and the like are displayed and voiced.

The chemical injection device 400 that has calculated the estimated value of the glomerular filtration value as described above also acquires the volume and iodine concentration of the chemical solution syringe 800 of the contrast medium as the chemical condition data, so that the total amount of iodine corresponding to the glomerular filtration value is obtained. The total injection amount is calculated so that

When the RFID chip 810 is not mounted on the drug solution syringe 800, it is naturally not detected by the RFID reader 416 (step S21-N) as shown in FIG. 20, so that the injection condition data and serum creatinine are as described above. Injection control data is generated and set from the value and weight (step S25).

When the setting of the injection control data is completed as described above, the set injection control data and the like are displayed and output on the touch panel 403 and the head display 415 as shown in FIG.

Further, in the drug solution injection device 400 of the present embodiment, when setting manually without setting the injection control data from the injection condition data as described above (steps S4 to S11), the drug solution syringe 800 is set as described above. It is effective to acquire chemical condition data from the RFID chip 810 and set it as injection control data (steps S5 to S8).

As described above, a part of the display and voice output of the chemical condition data includes the product name and the expiration date that are useful to be confirmed by the infusion operator. In addition, a part of the chemical condition data used for generating the injection control data is naturally composed of a capacity, a withstand voltage, etc. useful as the injection control data.

However, when the injection condition data is acquired from the imaging order data and the setting of the injection control data is completed (steps S12 to S28), the chemical injection device 400 of the present embodiment performs the chemical injection in this state. It is not ready to start.

Therefore, when the injection operator completes the setting of the injection control data as described above (step S28-Y), the injection operator performs a final check such as whether or not air bubbles are mixed in the extension tube. The final confirmation switch 414 of the injection execution head 410 is input.

Then, the chemical injection device 400 that has detected this (step S29-Y) releases the operation lock of the chemical injection assuming that the final confirmation has been executed (step S30). However, in the chemical injection device 400 according to the present embodiment, even when the final confirmation is executed in this way and the operation lock is released, the chemical injection cannot be executed by itself.

That is, as shown in FIG. 22, when the final confirmation switch 414 is input as described above (step S29-Y), the medicinal solution injection device 400, in the control box 500, from the RIS 100 to the imaging order as in the first time. Data is acquired again, and a part thereof is acquired again from the control box 500 as injection condition data (step S31).

Then, the injection condition data set as the injection control data is compared with the injection condition data acquired again (step S32). If the injection condition data does not match (step S32-N), as shown in FIG. 16, an error guidance of a confirmation warning such as “Caution is different from the patient information acquired last time” is displayed on the touch panel 403 and the head display 415. Is displayed and output (step S33), and is output as audio.

In this case, for example, when confirmation completion is input to the touch panel 403 and the head display 415, the initial state is restored (step S3). For this reason, the injection operation is not started in a state where the imaging order data is changed.

On the other hand, when it is confirmed that the injection condition data set as the injection control data matches the injection condition data acquired again (step S32-Y), the start of injection can be input through the touch panel 403 and the head display 415. It becomes a state.

Therefore, when this injection start is input (step S34-Y), the syringe drive mechanism 412 is controlled in response to the set injection control data, and as shown in FIG. A contrast medium and physiological saline are appropriately injected as injection chemicals (step S35).

At this time, since the elapsed time is measured in real time and the actual injection speed is also detected, the operation of the syringe drive mechanism 412 is feedback controlled so that the injection speed matches the injection control data.

Furthermore, a time-lapse graph composed of the actual injection speed is generated in real time (step S36), and is displayed and output on the touch panel 403 and the head display 415 together with the injection control data (step S37).

As described above, when the injection control data is manually set without acquiring the injection condition data, the time-lapse graph is displayed and output together with the manually set injection control data as shown in FIG.

On the other hand, when the injection condition data and the chemical condition data are acquired and the injection control data is automatically set, as shown in FIG. 18, the time-lapse graph is automatically set as the injection control data, the injection condition data, the chemical condition data, etc. Is displayed and output. Further, in this case, the imaging start time acquired from the injection condition data is also displayed and output as a predetermined symbol mark on the time-lapse graph.

When the injection operation is completed by the automatic operation or the manual operation as described above (step 38-Y), injection history data including a time-lapse graph of the actual injection speed is generated (step S39).

When the injection control data is manually set without acquiring the injection condition data, the injection history data generated in this way is, for example, image data of a time-dependent graph, subject ID acquired from imaging order data, etc. Text data, text data of serum creatinine value acquired from the creatinine measuring device 920, text data of body weight acquired from the weight height meter 930, and the like.

The injection history data as described above includes, for example, an injection operation ID that is unique identification information for each injection operation, actual injection start and end dates and times, identification information of the liquid injector 400, injection control data, Information on whether all of the injection control data has been manually input or partly acquired from the imaging order data or partly acquired from the chemical condition data, and if acquired from the imaging order data, the first and second times Text data such as acquisition date and time, acquired injection condition data and chemical condition data are also set.

Furthermore, when chemical condition data is acquired from the RFID chip 810 of the chemical syringe 800, a part of the chemical condition data is also set as text data in the injection history data.

Such text data includes, for example, information on whether the chemical condition data is acquired from the RFID chip 810 or manually input, the product name of the injected chemical, the injected chemical ID, the chemical classification, the contained component, the expiration date, the cylinder pressure resistance, and the lot number. , Sales price, etc.

Then, when the injection operation is completed, the chemical injection device 400 also generates completion notification data that is given at least an injection operation ID and notifies the completion (step S40). Therefore, the chemical injection device 400 that has completed the injection operation transmits completion notification data and injection history data to the control box 500 (step S41).

Then, the control box 500 transfers the completion notification data received from the chemical solution injector 400 to the RIS 100. The RIS 100 stores the received completion notification data in a state associated with the imaging order data by the injection work ID.

Further, the control box 500 transfers the injection history data received from the chemical solution injection device 400 to the PACS 300. The PACS 300 stores the received injection history data in a state managed by the imaging work ID.

In the normal operation, the imaging operation by the CT scanner 200 is started before and after the injection operation by the chemical injection device 400 is completed as described above. In that case, the start of imaging is input to the imaging control unit 210 of the CT scanner 200 by the injection operator.

Then, the imaging control unit 210 of the CT scanner 200 transmits an imaging order data acquisition request to the RIS 100. Then, the RIS 100 returns one imaging order data selected as described above to the CT scanner 200.

Therefore, in the CT scanner 200, the operation of the fluoroscopic imaging unit 201 is controlled in accordance with the imaging order data received by the imaging control unit 210, whereby the imaging work of the fluoroscopic image data is executed.

When the fluoroscopic image data is captured from the imaging subject by the fluoroscopic imaging unit 201, the imaging control unit 210 adds imaging order data to the fluoroscopic image data. Next, in the imaging control unit 210, the fluoroscopic image data to which the imaging order data is added is transmitted to the PACS 300.

The PACS 300 stores the received fluoroscopic image data in a state managed by the imaging work ID of the imaging order data. When the injection operator browses the fluoroscopic image data, for example, the fluoroscopic image data is read from the PACS 300 by a manual operation of the image browsing device 600.

In this case, for example, when the imaging work ID is input as a search key, the fluoroscopic image data of the imaging work ID is read from the PACS 300 and displayed on the display unit 602 of the image browsing apparatus 600.

At this time, since the injection history data is also read from the PACS 300 by the imaging work ID, it is displayed on the display unit 602 of the image browsing apparatus 600 as necessary.

According to the injection history data displayed and output in this way, the injection condition data of the injection work is manually input or acquired from the imaging order data, or the serum creatinine value is acquired from the imaging order data or acquired from the creatinine measuring device 920. Whether the body weight is acquired from the imaging order data, acquired from the body height meter 930 or manually input, whether the medical condition data is acquired from the medical syringe 800 or manually input, and the like are also confirmed.

In the chemical injection device 400 of the present embodiment, the syringe drive mechanism 412 is controlled by the injection control unit 421 in response to the injection control data set as described above, so that the syringe drive mechanism 412 is loaded. The medicinal solution syringe 800 is driven to inject the injected medicinal solution into the imaging subject.

In the chemical solution injection device 400 according to the present embodiment, the syringe drive mechanism 412 is controlled in accordance with the injection control data set by the injection control unit 421 as described above to execute the chemical solution injection.

However, the renal function data of the subject to be imaged is acquired by the data input unit 422 prior to the execution of the medicinal solution injection, and the injection setting data corresponding to the acquired renal function data is generated by the control setting unit 423 to the injection control unit 421. Set.

For this reason, it is possible to optimally control the operation of medicinal solution injection corresponding to the renal function of the imaging subject. Therefore, it is possible to easily and surely prevent the injection of a medical solution such as a contrast medium to an imaging subject having a poor renal function, in the same manner as the injection of a chemical solution to an imaging subject having a good renal function.

Moreover, the medicinal solution injection device 400 of the present embodiment calculates the estimated value of the glomerular filtration rate as (140−age) × body weight / 72 × serum creatinine value from the acquired serum creatinine value, age and weight.

Furthermore, the chemical injection device 400 also acquires the volume and iodine concentration of the contrast medium chemical syringe 800 as the chemical condition data, thereby calculating the total injection amount so as to be the total iodine amount corresponding to the glomerular filtration value and performing injection control. Generate data. For this reason, injection control data appropriate for the subject to be imaged can be set easily and reliably.

In particular, the chemical injection device 400 according to the present embodiment can obtain the serum creatinine value from the creatinine measurement device 920 when the serum creatinine value is not set in the imaging order data. Similarly, when the weight is not set in the imaging order data, it can be acquired from the weight height meter 930. For this reason, the chemical injection device 400 can easily and immediately obtain the latest appropriate serum creatinine value and body weight from the imaging subject.

It should be noted that the injection condition data including the imaging subject ID and the like is input using a dedicated icon with a logo “i” and a schematic image of the human body. For this reason, the injection operator can intuitively execute the acquisition operation of the injection condition data.

Furthermore, in the fluoroscopic imaging system 1000 of the present embodiment, the chemical condition data is recorded on the RFID chip 810 of the chemical syringe 800, and the chemical injection device 400 acquires the chemical condition data from the RFID chip 810 with the RFID reader 416. . For this reason, the chemical injection device 400 can easily and reliably acquire large-volume chemical solution condition data from the chemical syringe 800.

In particular, the chemical injection device 400 does not acquire chemical condition data unless the chemical syringe 800 is properly loaded. For this reason, it is possible to prevent the chemical liquid injection from being executed in a state where the chemical liquid syringe 800 is not properly loaded.

Furthermore, the drug solution injection device 400 of the present embodiment generates injection control data in which the total amount of drug solution injection is adjusted in accordance with the renal function data. For this reason, the total amount of iodine injected into the imaging subject can be appropriately regulated, and side effects caused by the contrast agent can be prevented appropriately.

Further, the chemical condition data acquired from the RFID chip 810 is displayed and output together with a predetermined logo mark “RFID”. For this reason, the injection operator can intuitively confirm that the displayed chemical solution condition data has been acquired from the RFID chip 810.

Particularly, the display output as described above is displayed and output not only on the touch panel 403 of the injection control unit 401 of the chemical injection device 400 but also on the head display 415 of the injection execution head 410. Therefore, the injection operator can check the injection condition data and the chemical condition data while working at the position of the injection execution head 410.

Moreover, the drug solution injection device 400 of the present embodiment outputs the kidney function data, the drug solution condition data, the injection control data, and the like together with the display output. For this reason, various data can be surely confirmed by a busy injection worker.

Furthermore, when the final confirmation immediately before the injection is input, the chemical injection device 400 according to the present embodiment again acquires the injection condition data as a part of the imaging order data from the RIS 100, and again returns the injection condition data acquired in advance. Confirm the match with the acquired injection condition data.

Since the chemical solution injection by the injection control data is not executed until the coincidence is confirmed, it is possible to easily and reliably prevent the injection operation from being executed with the inappropriate injection control data.

For example, when the imaging schedule is suddenly changed and the imaging order data is corrected or deleted, the injection operation is not started corresponding to the first imaging order data.

Furthermore, the fact that the imaging order data does not match is informed and output to the injection operator by the chemical injection device 400, so that the injection operator can reliably recognize and confirm the change of the imaging order data.

However, when all of the injection control data is manually input, the injection operation can be started when the setting of the injection control data is completed. For this reason, it is possible to appropriately control the prohibition and banning of the injection operation under simple conditions.

Further, in a general injection operation using the chemical solution injection device 400, the injection control data is set by the injection control unit 401 separated from the injection execution head 410 as described above. The state of the liquid syringe 800 and the imaging subject is finally confirmed at the position.

And in the chemical injection device 400 of the present embodiment, the final confirmation switch 414 for acquiring the imaging order data again and confirming the match immediately before the injection is arranged in the injection execution head 410 as described above.

For this reason, it is possible to input the acquisition of the imaging order data again and the coincidence confirmation at the time of the final confirmation at the position of the injection execution head 410 that has been conventionally required. Particularly, in this chemical solution injection device 400, the operation lock of the chemical solution injection is not released unless the final confirmation is executed and the final confirmation switch 414 is input.

For this reason, only by inputting one final confirmation switch 414, the unlocking of the injection operation by the final confirmation completion input and the reconfirmation of the imaging order data can be performed together.

Furthermore, in the chemical solution injection device 400, when an injection operation is executed based on the injection control data, a time graph is displayed and output in real time. For this reason, the injection operator can confirm the injection state in real time.

In particular, when injection control data is generated with imaging order data acquired from the PACS 300, the various setting contents are displayed and output together with a time-dependent graph. Therefore, the injection operator can always check the setting contents of the imaging order data used for the injection control data.

Furthermore, in the chemical injection device 400 of the present embodiment, when imaging order data is acquired from the RIS 100, the imaging start time is displayed and output on a time-dependent graph based on the imaging order data.

For this reason, the injection operator can confirm the relationship between the injection status and the imaging start time in real time. In particular, since the imaging start time is displayed and output by a dedicated logo mark, the injection operator can confirm intuitively.

Furthermore, the chemical injection device 400 according to the present embodiment generates injection history data including the operation history of the syringe drive mechanism 412 corresponding to the injection control data, and transmits the generated injection history data to the PACS 300 to transmit fluoroscopic image data. Save with.

In particular, the liquid injector 400 according to the present embodiment also registers renal function data, injection control data, and liquid condition data in the injection history data. For this reason, when checking the injection history data, it is also possible to check the kidney function data, the injection control data, and the liquid condition data. Therefore, the injection operator who browses the fluoroscopic image data can easily and surely confirm that the chemical injection has not been performed improperly on the imaging subject having a poor renal function.

In addition, as described above, the fluoroscopic image data and the injection history data are related by the imaging work ID, and the imaging work ID is acquired by the liquid injector 400 as imaging order data when the injection control data is automatically set. The

That is, the imaging order data acquired from the RIS 100 via the control box 500 to the drug solution injector 400 can be used for both setting of injection control data and generation of injection history data.

Moreover, the various apparatuses 100 to 600, 900 of the fluoroscopic imaging system 1000 of the present embodiment mutually communicate various data according to the DICOM protocol. Since DICOM communication data is difficult to falsify, the evidence capacity of injection history data, injection control data, and chemical condition data is high.

Moreover, the completion notification data of the injection operation is stored in the RIS 100 from the chemical injection device 400 via the control box 500. In the RIS 100, since the completion notification data is managed in association with the imaging order data, the RIS 100 can notify the CT scanner 200 of the start time, the end time, etc. of the liquid injection together with the imaging order data.

In this case, since the injection operator who operates the CT scanner 200 can refer to the start time and end time of the chemical solution injection, the start time of image capturing can be adjusted in accordance with the time.

In addition, this invention is not limited to the said form, A various deformation | transformation is accept | permitted in the range which does not deviate from the summary. For example, in the above embodiment, the drug injection device 400 acquires personal condition data in which the serum creatinine value, age, and weight are set, and the estimated value of the glomerular filtration rate is (140−age) × body weight / 72 × serum. The calculation as a creatinine value was exemplified.

However, the drug injection device 400 acquires personal condition data in which the serum creatinine value, age, weight and sex are set, and the estimated value of the glomerular filtration rate of the male is (140−age) × weight / 72 X Calculated as serum creatinine value, gender estimated value of glomerular filtration rate of female (140-age) x body weight / 72 x serum creatinine value x 0.85
May be calculated as

Alternatively, the drug injection device 400 may acquire the serum creatinine value, age, and sex as the kidney function data, and calculate the estimated value of the glomerular filtration rate based on the acquired serum creatinine value, age, and sex.

In that case, the estimated value of glomerular filtration rate of male gender is 194 × power of serum creatinine value−1.094 × age−0.287
The estimated value of glomerular filtration rate for females with gender was calculated as (194 × power of serum creatinine value−1.094 × age−0.287) × 0.739
May be calculated as

On the other hand, the estimated value of glomerular filtration rate of male gender is 175 × serum creatinine value−1.154 × age−0.203 × 0.741
And the estimated value of glomerular filtration rate for female gender is 175 × serum creatinine value−1.154 × age−0.203 × 0.742
May be calculated as

However, there are various methods for calculating the estimated value of the glomerular filtration rate, and any of them can be used for the chemical liquid injector 400. Similarly, as the renal function data, there are various data that can be used for the drug solution injector 400.

For example, 24-hour endogenous creatinine clearance (Ccr), DuBois BSA, or the like may be used in the liquid injector 400 as renal function data. Further, when the subject is a child, the chemical injection device 400 may calculate the estimated value of the glomerular filtration value by the Schwartz equation.

The medicinal solution injection device 400 stores a list and a nomograph for specifying an estimated value of the glomerular filtration value from the serum creatinine value and the age, and the glomerular filtration is performed from the serum creatinine value and the age by the list and the nomograph. An estimated value of the value may be specified. In that case, a list or nomograph may be stored for each gender.

In addition, when the estimated value of the glomerular filtration value calculated and specified as described above is smaller than a predetermined numerical value such as 40 to 60, warning guidance is output by voice or display, the injection operation is restricted, May be.

In the above embodiment, the chemical injection device 400 generates injection control data corresponding to body weight and age. However, the chemical injection device 400 may also acquire the body surface area, and the control setting unit 423 may correct the estimated value of the glomerular filtration value with the acquired body surface area.

Furthermore, the medicinal solution injection device 400 may acquire the height as renal function data, and calculate the body surface area from the acquired height and weight. In this case, naturally, the chemical injection device 400 calculates the glomerular filtration value from the body surface area rather than the body weight. The height and weight can be obtained from the weight height meter 930 at a time.

In the above embodiment, the liquid injector 400 generates injection control data in which the total liquid injection volume is adjusted according to the renal function data. However, injection control data in which one or all of the total injection amount, injection time, and injection rate are adjusted in accordance with the renal function data may be generated. That is, in addition to reducing the total amount of injection corresponding to the renal function of the subject to be imaged, it is only necessary to reduce the injection rate or shorten the injection time.

Furthermore, in the above embodiment, it is assumed that the drug solution injection device 400 also injects physiological saline as the injection drug solution together with the contrast agent, and generates injection control data of the contrast agent corresponding to the renal function data.

However, the injection control data for both the contrast medium and the physiological saline may be generated corresponding to the renal function data. In that case, for example, injection control data in which the injection ratio of the contrast medium and physiological saline is adjusted in accordance with the kidney function data may be generated.

Further, the medicinal solution infusion apparatus 400 may generate infusion control data in which an infusion change pattern that changes the infusion rate of medicinal solution infusion corresponding to renal function data is adjusted by a predetermined algorithm.

Furthermore, in the above embodiment, the injection control data is generated by calculating the glomerular filtration value from the serum creatinine value acquired by the drug solution injection device 400. However, if the acquired serum creatinine value or the calculated glomerular filtration value deviates from a predetermined allowable range, it may be determined that renal function is defective. In this case, the allowable range may be set for each imaging subject, or may be selected as common data.

In addition, a side effect history for each injected medicinal solution is registered in the electronic medical record and imaging order data for each subject to be imaged. As shown in FIG. 23, a warning guidance is output when consistency with the medicinal solution condition data is confirmed. Also good. In this case, the presence or absence of side effects can be confirmed more easily and reliably.

In the above embodiment, the serum creatinine value and the body weight are stored in the PACS 300 by the drug injection device 400 together with the injection history data. However, the medicinal solution injection device 400 may return the serum creatinine value and the body weight to the RIS 100 and the HIS 900 and store them together with the imaging order data and the subject electronic medical record.

Furthermore, in the above embodiment, the chemical liquid condition data is recorded in the chemical liquid syringe 800 with the RFID chip 810, and the chemical liquid injection device 400 acquires the chemical liquid condition data with the RFID reader 416.

However, the chemical condition data is recorded on the chemical syringe with a magnetic stripe, a two-dimensional code, or a barcode, and such chemical condition data may be acquired by the chemical injection device with a magnetic head, a two-dimensional scanner, or a line scanner. (Not shown).

Further, in the above embodiment, it is exemplified that various data are included in the chemical condition data recorded in the chemical syringe 800. However, the liquid condition data recorded in the liquid syringe may be the injection liquid ID alone.

In this case, for example, various data of the chemical condition data as described above are recorded in a database such as HIS900, RIS100, and PACS300 together with the infusion chemical ID, and the various data of the chemical condition data are searched by the infusion chemical ID. What is necessary is just to be acquired by the injection | pouring apparatus (not shown).

Furthermore, in the above embodiment, it is assumed that the chemical syringe 800 is a prefilled syringe and the chemical solution condition data is recorded by the syringe manufacturer. However, the chemical solution syringe may be a refill syringe, and the chemical solution condition data may be recorded at the medical site corresponding to the injecting chemical solution to be filled.

In the above embodiment, the chemical injection device 400 automatically sets the injection control data based on the imaging order data acquired from the RIS 100 and the chemical condition data acquired from the chemical syringe 800.

However, such injection control data is registered in the PACS 300 and the like together with the injection history data and the imaging subject ID, and the injection control data is acquired from the PACS 300 and the like by the imaging subject ID and used for the injection operation. May be.

In this case, if imaging work has been executed in the past by the same imaging subject, the past injection control data can be used again. For this reason, even when a complicated injection operation is set by injection control data, the injection operation can be easily reproduced.

Further, the injection history data generated together with the injection work in the chemical solution injection device 400 is registered in the PACS 300 together with the imaging subject ID and the injection history data is acquired from the PACS 300 to the chemical injection device 400 by the imaging subject ID and the injection control data. May be used for injection work.

In this case, it is necessary to generate injection control data from the injection history data in the chemical injection device 400. However, if the injection history data is registered in the PACS 300, registration of the injection control data can be made unnecessary.

In addition, the past injection control data acquired from the PACS 300 to the chemical injection device 400 in this way may be automatically adjusted corresponding to the new injection condition data. As such injection condition data, the body weight of the subject to be imaged, the component concentration of the injected drug solution, the components contained in the injected drug solution, and the like can be used.

For example, if the weight of the imaging subject given to the past injection control data acquired from the PACS 300 to the chemical injection device 400 is 50 kg and the current weight input to the chemical injection device 400 is 60 kg, the injection control is performed. Processing operations such as increasing the data injection speed and total injection amount by 1.2 (= 60/50) times are preferable.

Similarly, if the component concentration of the injected drug solution given to the past injection control data is 10% and the current component concentration acquired as the drug solution condition data in the drug solution injector 400 is 20%, the injection control data Processing operations such as increasing the injection speed and the total injection amount by 0.5 (= 10/20) times are preferable.

Further, in the above embodiment, the imaging subject ID, the imaging site, and the like are acquired by the chemical injection device 400 from the imaging order data registered in the RIS 100, so that the injection operator inputs the imaging subject ID and the like to the chemical injection device 400. It is not necessary to do this, and it is illustrated that it is possible to prevent the erroneous input. However, some or all of the above-described imaging subject ID, imaging site, and the like may be input to the chemical injection device 400.

Further, the fluoroscopic imaging system 1000 has a subject management medium (not shown) for each imaging subject on which an RFID chip in which at least an imaging subject ID is recorded is mounted, and the liquid injector 400 is a subject management medium. An imaging subject ID or the like may be acquired from the RFID chip.

The subject management medium as described above can be realized, for example, as a medical record file on which an RFID chip is mounted, a management armband attached to the arm of the imaging subject (not shown), or the like. In this case, the input operation of the imaging subject ID by the injection operator can be made unnecessary, and erroneous input can be prevented.

In addition, personal condition data such as serum creatinine value, body weight, and side effect history is also registered in the RFID chip of such a subject management medium, and this is acquired by the drug injection device 400 to automatically set injection control data and kidneys. You may make it use for determination of a malfunction.

Further, in the above embodiment, it is exemplified that the change of the imaging order data can be dealt with when the chemical injection device 400 acquires and confirms the injection condition data of the imaging order data of the RIS 100 immediately before the injection.

However, the liquid injector 400 confirms the match between the imaging subject ID acquired from the imaging order data of the RIS 100 and the imaging subject ID acquired from the RFID chip of the subject management medium, and the syringe is driven until the match is confirmed. The operation control of the mechanism 412 may be prohibited, and if a match is not confirmed, a predetermined confirmation warning may be output.

Furthermore, in the above embodiment, only the chemical solution condition data acquired from the chemical solution syringe 800 by the chemical solution injection device 400 is used for setting injection control data. However, the chemical solution condition data acquired from the chemical syringe 800 by the chemical injection device 400 as described above may be transmitted to the HIS 900.

This HIS 900 generally performs accounting processing for each imaging operation. Therefore, if the HIS 900 can acquire the liquid condition data of the injected liquid actually injected into the imaging subject, the above-described accounting process can be executed easily and quickly.

In this case, the chemical liquid injector 400 can notify the HIS 900 of the chemical condition data of the plurality of chemical syringes 800 when, for example, the plurality of chemical syringes 800 are consumed due to an operation error or the like.

In such a fluoroscopic imaging system (not shown), even if the chemical syringe 800 is registered as one or the like in the imaging order data, the accounting process is executed with the number of actually consumed chemical syringes 800. be able to.

Furthermore, when a plurality of injection control data corresponding to the imaging subject ID provided by the drug injection device 400 is registered in the PACS 300 in the above form, the plurality of injection control data is transmitted from the PACS 300 to the drug injection device 400, An example in which the latest one injection control data is selected by the chemical injection device 400 is illustrated.

However, the latest one injection control data may be selected by the PACS 300 and transmitted to the chemical solution injection device 400. In this case, a dedicated processing operation is required for the PACS 300, but congestion can be prevented by reducing the transmission data capacity.

Also, a plurality of injection control data transmitted from the PACS 300 may be displayed in a list by the chemical solution injection device 400, and one of the displayed injection control data may be selected. In this case, the injection operator can select optimal injection control data as desired. Furthermore, from a plurality of injection control data transmitted from the PACS 300, the chemical solution injection device 400 may select one corresponding to a predetermined condition such as the closest weight.

Further, in the above embodiment, all of the imaging order data managed by the RIS 100 is acquired in the control box 500, and a part of the imaging order data is acquired as injection condition data from the control box 500 to the chemical solution injector 400. Illustrated. However, all of the imaging order data may be acquired by the liquid injector 400 as injection condition data.

Furthermore, in the above embodiment, the RIS 100 is a push type, and the control box 500 is exemplified to acquire appropriate imaging order data at the timing. However, the RIS 100 may be a pull type.

In this case, the CT scanner 200 transmits an imaging order data acquisition request to the RIS 100 together with at least one order search key. Then, the RIS 100 selects and returns one of the plurality of imaging order data corresponding to the acquisition request received from the CT scanner 200 and the order search key.

And the control box 500 transmits the acquisition request of the imaging order data received from the chemical injection device 400 to the RIS 100. Then, the RIS 100 returns one imaging order data selected corresponding to the acquisition request received from the control box 500.

Or, the RIS 100 returns a plurality of imaging order data in response to the acquisition request received from the CT scanner 200. In this case, the CT scanner 200 receives an operation for selecting one of the returned plurality of imaging order data, and notifies the RIS 100 of the selected imaging order data.

Alternatively, the RIS 100 searches for a part from a plurality of imaging order data in response to the acquisition request received from the CT scanner 200 and the order search key, and returns a response. The CT scanner 200 accepts an operation for selecting one of the returned imaging order data, and notifies the RIS 100 of the selected imaging order data.

Therefore, when the control box 500 transfers the acquisition request for the imaging order data to the RIS 100, the RIS 100 returns one imaging order data notified from the CT scanner 200 in response to the acquisition request received from the control box 500. .

By doing as described above, even if the RIS 100 is a pull type, the control box 500 can acquire appropriate imaging order data, and can give an imaging work ID or the like to the injection history data.

Furthermore, in the above embodiment, it is exemplified that the control box 500 acquires imaging order data from the RIS 100. However, the RIS 100 and the CT scanner 200 may be connected via the control box 500, and the control box 500 may acquire imaging order data transmitted from the RIS 100 to the CT scanner 200.

Further, the control box 500 may be connected to the CT scanner 200 without being connected to the RIS 100, and the control box 500 may acquire imaging order data from the CT scanner 200.

In this case, for example, the control box 500 transfers an acquisition request received from the chemical solution injector 400 to the CT scanner 200, and the CT scanner 200 returns imaging order data in response to the acquisition request received from the control box 500. That's fine.

Alternatively, the CT scanner 200 may accept an operation for selecting one of a plurality of imaging order data returned from the pull-type RIS 100 and transfer the selected imaging order data to the control box 500.

Further, the control box 500 may be connected to the RIS 100 and the CT scanner 200, the first imaging order data may be acquired from the RIS 100, and the confirmation imaging order data may be acquired from the CT scanner 200.

Furthermore, in the above embodiment, it is exemplified that the injection history data and injection control data generated by the chemical solution injection device 400 are stored in the PACS 300 together with the fluoroscopic image data generated by the CT scanner 200.

However, the injection history data and the injection control data may be transmitted from the chemical solution injection device 400 to the RIS 100 via the control box 500, and the injection history data and the injection control data may be stored in the RIS 100. In this case, the RIS 100 can manage the imaging order data, the injection history data, and the injection control data in association with the work ID.

Even in this case, the fluoroscopic image data registered in the PACS 300 is assigned the work ID of the imaging order data, so that the fluoroscopic image data can be associated with the injection history data and the injection control data.

Furthermore, in the above embodiment, the entire imaging order data is given to the fluoroscopic image data and stored in the PACS 300. However, only the imaging work ID of the imaging order data may be assigned to the fluoroscopic image data.

Even in this case, the fluoroscopic image data can be associated with the injection history data and the injection control data by the imaging work ID, and the imaging order data can be read from the RIS 100 by the imaging work ID.

Further, only the imaging work ID of the imaging order data may be assigned to the fluoroscopic image data, and all of the imaging order data may be added to the injection history data or the injection control data. The imaging order data may be added to the fluoroscopic image data, the injection history data, or the injection. It may be assigned to control data. Further, the entire display image of the touch panel 403 and the head display 415 of the chemical liquid injector 400 may be included in the injection history data.

In the above embodiment, only injection control data is set in the chemical solution injection device 400. However, the injection control data may be notified from the chemical injection device 400 to the control box 500, and the injection control data may be notified from the control box 500 to the RIS 100. In this case, the injection control data can be notified from the RIS 100 to the CT scanner 200 together with the imaging order data.

Therefore, since the injection operator who operates the CT scanner 200 can refer to the injection control data, the imaging operation can be adjusted according to the injection control data. It is not impossible to automatically adjust the imaging operation based on the injection control data acquired by the imaging control unit 210 of the CT scanner 200.

In the above embodiment, the injection history data is completed by the chemical solution injection device 400 and then transmitted to the control box 500. However, the chemical injection device 400 may distribute the injection history data to the control box 500 and transmit it, and the control box 500 may complete the injection history data.

More specifically, the chemical injection device 400 transmits injection control data, start date and time, etc. to the control box 500 at the start of injection, sequentially transmits the injection speed and the like in the injection process, and transmits end date and time, etc. at the end of injection. In this case, the injection history data can be completed and output from various data accumulated by the control box 500 from the start of injection to the end of injection.

Furthermore, in the above embodiment, the various devices 100 to 600 and 900 exemplify that the evidence ability such as injection history data is high by mutually communicating various data in DICOM format which is difficult to falsify. However, the chemical injection device 400 may generate injection history data in a data format that is difficult to falsify, such as PDF (Portable Document Format).

However, even in such a case, a plurality of hardware such as the RIS 100, the PACS 300, and the image browsing apparatus 600 may be connected in parallel (not shown).

Furthermore, in the above embodiment, it is exemplified that the fluoroscopic image data, injection history data, and injection control data are stored in one PACS 300. However, hardware for storing fluoroscopic image data, injection history data, and injection control data may be formed separately and connected via a communication network.

In the above embodiment, the RIS 100, the CT scanner 200, the PACS 300, the chemical solution injection device 400, the control box 500, the image browsing device 600, and the HIS 900 are formed separately and connected by the communication networks 700 to 706. Illustrated.

However, the various devices 100 to 600, 900 as described above may be integrally formed by various combinations. For example, the injection control unit 401 and the control box 500 of the chemical liquid injector 400 are integrally formed, the RIS 100 and the PACS 300 are integrally formed thereon, and the PACS 300 and the image browsing device 600 are integrally formed. It is also possible.

It is also possible that the RIS 100 and the PACS 300 are integrally formed in the control box 500, the control box 500, the PACS 300, and the image browsing device 600 are integrally formed.

Furthermore, the imaging control unit 210, the RIS 100, and the control box 500 of the CT scanner 200 are integrally formed, and the imaging control unit 210, the PACS 300, and the control box 500 of the CT scanner 200 are integrally formed. It is also possible for the image browsing apparatus 600 to be formed integrally therewith.

It is also possible that the image browsing device 600 and the PACS 300 are integrally formed, and that the control box 500 and the imaging control unit 210 of the CT scanner 200 are formed integrally therewith.

Furthermore, in the above embodiment, the creatinine measuring device 920 and the weight height meter 930 are exemplified as being directly connected to the drug solution injector 400. However, the creatinine measuring device 920 and the weight height meter 930 may be connected to the drug solution injector 400 via the control box 500, the RIS100, or the HIS900.

Further, in the above embodiment, the case where the chemical injection device 400 acquires the age of the subject to be imaged by registering the imaging order data of the RIS 100 from the electronic medical record of the HIS 900 in which the age is registered is exemplified. However, it is not impossible for the chemical injection device 400 to acquire the age of the subject to be imaged from a so-called Juki net or the like via the control box 500, the RIS 100, or the HIS 900.

Furthermore, in the above embodiment, it is exemplified that each unit of the various devices 100 to 600, 900 is logically realized as various functions by operating the computer device corresponding to the computer program.

However, it is possible to form each part as unique hardware, and it is possible to form a part as software and a part as hardware.

Of course, the embodiment and the plurality of modifications described above can be combined within a range in which the contents do not conflict with each other. In the above-described embodiments and modifications, the structure of each part has been specifically described. However, the structure and the like can be variously changed within a range that satisfies the functions of the present invention.

This application claims priority based on Japanese Patent Application No. 2008-164457 filed on June 24, 2008, the entire disclosure of which is incorporated herein.
