Abstract

A small-scale diagnostic system in which imaging order information is inputted into a medical terminal installed in an examination room and transmitted to a radiogram reader, and the radiogram reader associates the read image data with the order of reception of the imaging order information and transmits them to the medical terminal. In case of emergency, imaging can be quickly started without waiting the input of the imaging order information. For the purpose, the radiogram reader is controlled as follows. If imaging order information is received and if any interrupt mode is not set, the imaging order information stored in the descending order in an imaging order information storage section is written in the header portion of the read image data and the imaging order information is transmitted to the medical terminal. If the received imaging order information is not stored in the imaging order information storage information or if an interrupt mode is set, information representing that imaging is performed without imaging order information is written in the header portion of the read image data and the read image data is stored in the HDD of the radiogram reader.

Radiation image reader

Technical field

[0001] The present invention relates to a radiation image reading apparatus used in a small-scale diagnostic system mainly used in a small-scale medical facility.

Background art

[0002] Conventionally, an image of a patient to be examined is imaged by a technician using an image generation device such as a CR (Computed Radiography) device or an FPD (Flat Panel Detector) device, and the obtained image is diagnosed. In addition, a diagnostic system is known that performs image processing such as gradation processing so that it can be provided, outputs an image processed image, and provides it for interpretation by a doctor.

[0003] Such a diagnostic system accepts a patient who visits and issues a radiography order (acceptance), actually takes a patient in the radiographing room and generates image data (technologist), gradation, etc. Determining whether or not to provide diagnostics for the images obtained, and in some cases responsible for correcting contrast and density (engineers appointed from among general engineers, etc.), and judging the presence or absence of disease based on images (diagnosis) A number of persons in charge, such as a doctor in charge of interpretation (doctor), share the roles and proceed with the diagnosis.

[0004] And, in a large-scale medical facility (hereinafter referred to as a large-scale facility) for which application of a conventional diagnostic system is assumed, there are a plurality of image generation apparatuses and engineers who operate the image generation apparatus. A console for operating the image generating apparatus and a view screen for a doctor to check the image data are also provided separately with their respective roles. For this reason, there is a risk that the patient and the image data will be mistaken. Therefore, in order to prevent this, a system has been proposed in which each device is linked through a network, an ID is issued in each device, and the results of work processes performed in each device are associated with each other (for example, And Patent Document 1).

[0005] In such a system, the locations responsible for each of the above roles are often located in large hospitals, such as the reception floor on the first floor and the radiation department in the basement, etc. , Multiple patients, multiple technicians simultaneously using multiple imaging devices The scene is steady, and multiple patients are always staying in each process, so an ID is assigned to each work in each process so that there is no mistake in the correspondence between the generated image and each patient. , HIS (Hospital Information System) and RIS (Radiology Information System) are associated with each other (for example, see Patent Document 2 and Patent Document 3).

[0006] For example, at the 1F reception desk, the examination content (imaging content) is determined based on the patient's chief complaint, and registered along with the patient name. As a result, a patient list as shown in FIG. 10 (a) is created. The above patient list is added at any time and displayed on the first-floor reception workstation (hereinafter referred to as “WS”). At the same time, the above patient list is stored in the radiology department of B 1 via a network such as RIS / HIS (here, `` console '' is in the radiology department, setting radiography conditions and RIS / HIS This is a workstation that displays radiographing order information and images of patients. In order to increase the efficiency of distributed processing, multiple consoles are usually provided. These consoles are also connected to each other via a network, and a predetermined inspection ID can be selected on any console. In order to prevent duplicate imaging among multiple technicians, a method of notifying the patient list that processing is in progress (e.g. changing the flashing display or color or specifying the same examination gives a beep warning) ) Is used.

[0007] The radiology engineer selects the examination ID to be taken from the displayed patient list using the console at his / her immediate vicinity, and sets the ID (force setting ID) of the CR plate (cassette) to be used. sign up. As a result, the force set ID registered in the “force set ID” field of the patient list is displayed as shown in FIG. 10 (b). For example, the technician moves to the radiology room with three force sets and takes the patient. Thereafter, the captured force set is read by a reading device. The reading device reads the force set ID affixed to the inserted force set, attaches it to the image data, transmits the force set ID, and finally generates the test ID (patient ID) and the generated image data. The correspondence of is attached. The generated image data is sent to the console where the technician has selected the examination ID and displayed on the console. At this stage, the imaging positioning is confirmed, and if the positioning is poor, re-imaging is performed, and it is also determined whether to apply density or contrast correction or frequency enhancement processing. After that, the image Save (waiting for diagnosis) to the server. An interpreting physician extracts and displays an image related to a predetermined patient from an image stored on the interpretation waiting server on a workstation in the interpretation room (often equipped with a high-definition monitor for the view function). Perform (diagnosis).

[0008] And, in a system used in such a large-scale facility, for example, information that affects insurance score calculation, such as whether imaging performed on a patient is simple imaging or contrast imaging. By registering the patient's examination ID, force set ID, etc., and associating the patient with the captured image, all information can be linked and managed in a centralized manner on the RIS / HIS server etc. It is summer.

However, according to the investigation by the inventors of the present application, in the case of a relatively small medical facility (hereinafter referred to as a small-scale facility) such as a medical practitioner or a clinic, the number of installed image generating devices There are many cases where a few assistants perform patient positioning, and when the assistant is informed of the positioning completion, the doctor controls the X-ray exposure switch, or the doctor himself performs all operations including patient positioning. Les.

[0010] In addition, for example, in the case of a large-scale facility, it is assumed that the patient may have to travel between multiple floors in the facility after taking a picture until receiving a doctor's diagnosis. In the case of facilities, because the facilities are small, the distance traveled by the patient after taking a picture until receiving a doctor's diagnosis is short.

[0011] Under such circumstances, it is difficult to think of mistakenly taking a captured image with that of another patient. Using a system similar to a large-scale facility, imaging order information that begins with the input of the patient's name Generation work is required, and the procedure is rather complicated and the medical efficiency is poor.

[0012] In addition, in order to generate imaging order information such as patient information and examination information of a patient in advance and associate the imaging order information with a captured image, each network is compatible with a core system such as RISZHIS. A system for connecting devices is required. However, there is a problem that it is expensive to construct such a system, which is a burden for small-scale facilities. In addition, even if the number of devices is reduced while maintaining the configuration concept for large-scale facilities described above, it is not optimal for small-scale facilities.

[0013] Therefore, Patent Document 4 discloses an information input / output device arranged in an examination room and a radiological image information reading device in a radiographing room as systems for small-scale facilities such as practitioners and clinics. The patient ro information and imaging information input by the doctor from the information input / output device are transmitted to the radiological image reading device, and the I image of the patient to be imaged is displayed on the display unit of the radiographic image reading device. A system for displaying blueprints and shooting information is described.

[0014] Further, in Patent Document 5, information related to imaging such as patient information and examination information is sequentially input, information related to multiple imaging is stored in the input order, and information related to imaging is stored in the stored order. When a medical terminal that sends images to the radiation reader and a recording medium that has been imaged are set according to the order received from the medical terminal, the radiographic image recorded on the recording medium is read to generate image data. In addition, there is described a system including a radiation image reading device that associates generated image data with information related to imaging and transmits the information to a medical terminal. Further, Patent Document 5 does not have a function of associating scanned image data with information related to imaging in the radiation image reading device, and the radiation image reading device stores the read image data in the medical terminal. The image data received and received from the radiation image reading device is stored in the memory in association with the time data in the medical terminal, and the operator confirms the time when the image data was received, and the image data And a radiographic imaging system that associates patient information, examination information, and the like.

Even in this case, it is not possible to take a picture without waiting for the doctor to input the picture information. In particular, when doctors are examining other patients, nurses and radiographers cannot enter the room from the viewpoint of personal information protection, and it is difficult to request the issuance of radiographing information. That is not preferable. [0016] Further, Patent Document 5 includes both the radiation image reading device in the former system and the radiation image reading device in the latter system configuration, and the latter radiation image reading device is used in an emergency. However, it is necessary to provide separate radiological image readers for emergency and other systems, and the above problem cannot be solved by a single radiographic image reader.

When a plurality of photographings are performed on a single patient under a plurality of photographing conditions, steps S4 to S6 are repeatedly executed, and a plurality of pieces of photographing order information are generated. The imaging order information storage unit 333 stores imaging order information in association with the input order.

[0068] In the reading device 202, when the imaging unit information is received from the control device 3 by the communication unit 24, the received imaging order information is associated with the number indicating the reception order and the imaging order information storage unit A photographic order information screen 231 that is stored in 261 (step S7) and displays the received photographic order information is displayed on the display unit 23 (step S8).

FIG. 7 shows an example of a shooting order information screen 231 that displays shooting order information. On the screen 231, the shooting order information associated with the head order in the shooting order information storage unit 261 is displayed. Since the imaging order information includes patient information, imaging region, and the like, the imaging operator can grasp the imaging target patient and imaging region to be performed next on the screen.

[0070] According to the imaging order information displayed on the display unit 23, the imaging operator performs imaging of the patient in the imaging apparatus 201, attaches the already-captured force set to the reading apparatus 202, and inserts the cassette. The radiographic image information recorded in is read.

[0071] In the reading device 202, when an imaged force set is attached (step S9), the image generation unit 27 reads the radiation image information recorded on the attached force set, and image data is read. Is generated (step S10), and the reduced image is based on the scanned image. A (thinned image) is generated and displayed on the display unit 23 (step SI 1). When the photographer confirms the image and the NG button on the operation unit 22 is pressed due to improper positioning (step S12; NO), the process returns to step S8, and re-shooting is performed. Steps S8 to S11 are executed. When the OK button on the operation unit 22 is pressed (step S12; YES), the captured order information displayed in step S8 is associated with the read image data (for example, written in the header portion of the image data). (Step S13), the data is transmitted to the control device 3 via the communication unit 24 (Step S14).

In control device 3, when image data is received via communication unit 36, the received image is stored in temporary storage unit 331 (step S15).

In the reading apparatus 202, when transmission of the generated image data is completed, the imaging order information stored in the imaging order information storage unit 261 in the first order is deleted (step S16). . In the next step, it is determined whether or not there is information stored in the imaging order information storage unit 261. If it is determined that it is stored (step S17; YES), the process returns to step S8. Shooting is performed according to the next shooting order information. If there is no information stored, the process ends.

When the imaging is completed, the patient moves to the examination room 13. By operating the input unit 34 of the control device 3, the doctor displays an image search screen (not shown) on the display unit 35 and inputs the patient information of the target patient. In the control device 3, an image search screen is displayed according to the operation of the input unit 34, and patient information input is received via the input unit 34. When an image search screen is displayed and patient information is input from this screen via the input unit 34 (step S18), image data associated with imaging order information including the patient information of the input patient is temporarily stored. The image data extracted from the unit 331 is subjected to image processing such as gradation processing and frequency emphasis processing, and a thumbnail image is generated by reducing the image processed image data. This is displayed on screen 352 (step S19).

FIG. 8 shows a display screen example of the photographed image display screen 352 displayed on the display unit 35. As shown in FIG. 8, the photographed image display screen 352 has image display fields 352a to 352d for displaying a list of extracted images. When any one of the image display fields 352a to 352d is selected by the mouse or the like of the input unit 34, the selected image is displayed alone in the life size. Using this single display image, the doctor can observe the details of the image and make an interpretation diagnosis. Further, an image processing adjustment field 352e is provided in the upper right of the screen, and the doctor can adjust the density and contrast by operating the image processing adjustment field 352e with a mouse or the like. By pressing the 〇K button 352h displayed corresponding to each image, the displayed image can be confirmed as an image to be stored in the image DB 40. The captured image display screen 352 is provided with a patient information display field 352f for displaying patient information included in the imaging order information associated with the displayed captured image.

[0076] After image processing adjustment and image confirmation are performed from the captured image display screen 352 via the input unit 34 (step S20), the diagnosis end button on the captured image display screen 352 is pressed by the input unit 34. Thus, when the end of the diagnosis is instructed (step S21; YES), the image data corresponding to the displayed image and the imaging order information are transmitted to the server 4 via the communication unit 36, and are stored in the image DB 40. Is performed (step S22). The image data written in the image DB 40 of the server 4 is deleted from the temporary storage unit 331 (step S23).

[0077] As described above, in the small-scale diagnosis system 1, when the doctor inputs the imaging order information in the control device 3, the imaging order information is transmitted to the reading device 202 and displayed on the display unit 23. The The shooter performs shooting according to the shooting order information displayed on the display unit 23 and attaches the force set that has been shot to the reader 202. In the reading device 202, an image is read from the attached force set and image data is generated, and the generated image data is associated with the imaging order information displayed on the display unit 23, and is transmitted to the control device 3. Sent. In the control device 3, the received image data is displayed and image diagnosis is performed and stored in the server 4.

Note that, in a case where imaging is crowded, imaging order information may be transmitted from the control device 3 while imaging is being performed on the previous patient by the reading apparatus 202. In such a case, the received imaging order information is stored in the imaging order information storage unit 261 in association with a number indicating the reception order. The display unit 23 displays the shooting order information stored in the first order among the shooting order information stored in the shooting order information storage unit 261, and performs shooting according to the displayed shooting order information. When the force set that has been photographed is attached to the reader 202, the force set is read and the image data is read. Data is generated, and the generated image data is stored in the first order, and is transmitted to the control device 3 in association with the imaging order information. When the image data is transmitted to the control device 3, the first imaging order information displayed on the display unit 23 is deleted from the imaging order information storage unit 261, and the next imaging order information is displayed on the display unit 23. . In this way, photographing and reading are sequentially performed. In the control device 3, the image data transmitted by the reading device 202 is displayed and used for diagnosis by a doctor.

[0079] In the normal processing flow described above, a reception device is used for shooting and reading.

It is necessary to issue the acceptance input in 5 and issue of imaging order information by the doctor in the control device 3. However, in the normal processing flow, even in the case of an urgent patient, or in the case of a re-photographed patient who can take the same image as the previous one without having to consult a doctor. Even if there is, we can't take a picture without waiting for the doctor to issue the order information. In particular, if the doctor is examining another patient, the nurse will not be able to enter the room from the viewpoint of personal information protection, and it will be difficult to request an imaging order, which will cause the patient to wait. It is not preferable.

Therefore, in the present embodiment, the reading device 202 controls the reading of the attached force set by the reading control process shown in FIG. 9, so that even when there is no shooting order information, Alternatively, photographing and reading can be performed by interruption. When the interrupt button is pressed, ON is set in the interrupt flag area 251 of the RAM 25, and the reading of the next force set attached to the reader 202 is performed in the interrupt mode.

Hereinafter, a reading control process executed by the CPU 21 of the reading device 202 will be described. This process is a process realized by software processing by the cooperation of the CPU 21 and the storage unit 26.

[0082] When a force set is attached to the image generation unit 27 (step S101; YES), the imaging order information storage unit 261 is referred to and it is determined whether or not imaging order information is received from the control device 3. . When it is determined that the imaging order information received in the imaging order information storage unit 261 exists (stored) and the imaging order information is received from the control device 3 (step S102; YES), the interrupt flag Area 251 is referenced and interrupt mode is set It is determined whether or not it has been done. If it is determined that the interrupt mode is not set (step S103; NO), the radiographic image information recorded on the attached force set is read to generate image data (step S104). The thinned image is thinned and displayed on the display unit 23 (step S105). If the photographer confirms the image displayed on the display unit 23 and the NG button is pressed due to improper positioning (step S106; NO), this process ends. On the other hand, when the ◯ K button is pressed (step S106; YES), the imaging order information stored in the imaging order information storage unit 261 in the head order in the header part of the generated image data (that is, the reception order) Is captured first), the image data is associated with the image order information (step S107), and the image data associated with the image capture order information is associated with the image data. Is transmitted to the control device 3 by the communication unit 24 (step S108). Then, the image data stored in the first order in the photographing order information storage unit 261 is deleted (step S109), and this process ends.

On the other hand, if the received imaging order information is not stored in the imaging order information storage unit 261 in step S102, that is, if it is determined that the imaging order information has not been received from the control device 3 (step S102). ; NO), or if it is determined that the interrupt mode is set (step S103; YES), the flow after step S110 is executed. That is, the radiographic image information recorded on the attached force set is read to generate image data (step S110), and the generated image is thinned and displayed on the display unit 23 (step S111). When the photographer confirms the image displayed on the display unit 23 and the NG button is pressed (step S112; NO), this process ends.

On the other hand, when the OK button is pressed (step S112; YES), information indicating that the image data has been read without shooting order information in the header portion of the generated image data (for example, a specific code such as 9999). Is written, the image data is associated with information indicating that it has been read without photographing order information (step S113), and stored in the HDD 28 (step S114). When the transmission button of the operation unit 22 is pressed and transmission of image data is instructed (step S115; YES), the process proceeds to step S117. On the other hand, if the send button is pressed, it will be incorrect (step S115; N〇), and the reference time set in advance after being saved. It is determined whether or not the interval has elapsed, and if it is determined that a preset reference time has elapsed (step S116; YES), the process proceeds to step S117. In step S116, the image data stored in the HDD 28 is transmitted to the control device 3 by the communication unit 24 (step S117), the interrupt flag area 251 is initialized (step S118), and the process is terminated. End.

In control device 3, when image data associated with information indicating that the image has been read without photographing order information is received from reading device 202, the image data is stored in unregistered data storage unit 3 32. Temporarily saved. Here, since imaging order information is not associated with image data, that is, patient information is not associated, it is desirable to associate image data with patient information immediately after reception. The correspondence between the image data and the patient information is performed according to the operation by the doctor, so it is necessary to send it when the doctor is not diagnosing another patient and is ready to perform the matching operation. There is. Therefore, the radiographer inquires the doctor of the transmission timing of the image data and presses the transmission button of the operation unit 22 to transmit the image data. In the case of a small-scale medical facility, the examination time for a single patient is limited and does not exceed a certain time (reference time). Therefore, this reference time is set in the reader 202 in advance, and the HDD 28 The image data may be automatically transmitted to the control device 3 when a reference time or more has elapsed since being stored in the control device 3.

The control device 3 performs the diagnosis of the image data captured without the imaging order information and the association of the patient information as follows, for example.

When display of image data stored in unregistered data storage unit 332 is instructed by input unit 34, captured image display screen 353 (not shown) is displayed. The captured image display screen 3 53 is stored in the unregistered data storage unit 332 in a field corresponding to the force image display field 3 52a to 352d, which is substantially the same screen as the captured image display screen 352 shown in FIG. The captured image of the image data is displayed, and the column corresponding to the patient name column 352f is an input column (patient information input column) for inputting the patient name corresponding to the displayed captured image. On this screen, input patient information, make image adjustments, confirm the image, perform image diagnosis, and then press the diagnosis end button to display the image displayed on the screen. The patient information is attached to the header area of the image data of the shadow image, and the image data attached with the patient information is transmitted to the server 4 and stored in the image DB 40. The image data transmitted to the server 4 is deleted from the unregistered data storage unit 332.

[0087] As described above, according to the reading device 202 of the small-scale diagnosis system 1, the image generation unit

When the force set is attached to 27, it is determined whether or not the imaging order information is received from the control device 3. If it is determined that the imaging order information is received, the interrupt flag area 251 is referred to. It is determined whether or not the force for which the interrupt mode is set (the switch signal is output). If it is determined that the interrupt mode is not set, the radiographic image information recorded in the attached cassette is read to generate image data, and the imaging order is added to the header of the generated image data. The imaging order information stored in the information storage unit 261 in the head order is associated by being written, and image data associated with the imaging order information is transmitted to the control device 3 by the communication unit 24. On the other hand, when it is determined that the received imaging order information is not stored in the imaging order information storage unit 261, or when it is determined that the interrupt mode is set, it is recorded in the attached force set. Radiation image information is read to generate image data, and information indicating that the image data has been read without imaging order information is written in the header portion of the generated image data so that the image data is stored in the HDD 28. The The image data stored in the HDD 28 is transmitted to the control device 3 when the transmission button is pressed or after a certain time has elapsed since the storage.

Therefore, the imaging order information is input by the control device 3 provided in the examination room and transmitted to the radiographic image reading apparatus, and the radiographic image reading apparatus associates the read image data with the order of reception of the imaging order information. In the small-scale diagnostic system 1 to be transmitted to the medical device, when the imaging order information from the control device 3 has not been received, the image data read from the force set obtained by radiography should be stored in the HDD 28. Therefore, it is possible to start shooting and reading quickly without waiting for input of shooting order information from the control device 3 in an emergency or the like.

[0089] Even when radiographing order information is received from the control device 3, image data read from a radiographically-set force set is received by pressing the interrupt button. The operation to transmit to the control device 3 in association with the current imaging order information can be switched to the operation to save in the HDD 28 without associating with the imaging order information. It is possible to start shooting and reading quickly without waiting for the input or order of shooting order information.

[0090] When storing image data in the HDD 28, information indicating that the image data is read without shooting order information is stored in association with the image data read without the shooting order information. It becomes possible to identify something.

Note that the description in the above embodiment is a preferred example of the small-scale diagnosis system 1 according to the present invention, and the present invention is not limited to this.

For example, in the above embodiment, the case where an HDD is applied as a storage means has been described as an example. However, the present invention is not limited to this, and any storage device that can read and write image data can be used.

In addition, the detailed configuration and detailed operation of each device constituting the small-scale diagnosis system 1 can be changed as appropriate without departing from the spirit of the present invention.
