Description

The present invention relates to a diagnostic system mainly used in a small medical facility.

  Conventionally, an image of a patient to be examined can be provided for diagnosis by a technician using an image generation device such as a CR (Computed Radiography) device or an FPD (Flat Panel Detector) device. A diagnostic system is known in which image processing such as gradation processing is performed so that an image processed image is output and provided for interpretation by a doctor.

  Such a diagnostic system was able to receive the patients who came to the hospital and issue the imaging order (acceptance), actually take the patient in the imaging room and generate the image data (engineer), the gradation, etc. Responsible for determining the availability of image diagnosis, and in some cases, responsible for correcting contrast and density (such as an engineer appointed from a general engineer), and interpreting in charge of determining (diagnosing) the presence or absence of disease based on images ( A plurality of persons in charge, such as doctors, share roles and diagnoses are advanced.

  In a large-scale medical facility (hereinafter referred to as a large-scale facility) where application of a conventional diagnosis system is assumed, there are a plurality of image generation apparatuses and engineers who operate the image generation apparatus. A console for operation and a viewer for checking image data by a doctor or the like are also provided separately with respective roles. For this reason, there is a possibility that the patient and the image data are 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, patents). Reference 1).

  In such a system, the locations in charge of each of the above roles are often located in large hospitals such as the reception floor 1F and the radiology department underground, and multiple patients within the radiology department. The situation where a plurality of engineers use a plurality of imaging devices to perform imaging simultaneously is stationary, and a plurality of patients are constantly staying in each process, and the generated images and individual patients are In order to ensure that there is no mistake in the mapping, an ID is assigned to each work in each process, via a network of HIS (Hospital Information System) or RIS (Radiology Information System) The association is performed (see, for example, Patent Document 2 and Patent Document 3).

  For example, at the 1F reception desk, the photographing content is determined based on the patient's main complaint and registered together with the patient name. Thereby, a patient list as shown in FIG. 10A is created. The above patient list is added at any time and displayed on the 1F reception workstation (hereinafter referred to as “WS”). At the same time, the above patient list is stored in a console in the radiology department of the basement via a network such as RIS / HIS (here, “console” is in the radiology department, setting radiography conditions, and taking radiography orders of RIS / HIS). This is a workstation that displays information and images of patients. In order to increase the efficiency of distributed processing, a plurality of consoles are usually provided, but these are also connected to each other via a network, and a predetermined shooting ID is selected at an arbitrary console. In order to prevent duplicate shooting among multiple technicians, a method of notifying that the patient list is being processed (flushing display, changing color, or beep warning if the same examination is specified, etc.) Used.

  A radiology engineer uses a console close to him / her, selects an imaging ID to be imaged from the displayed patient list, and registers an ID (cassette ID) of a radiation image conversion medium (cassette) to be used. As a result, the cassette ID registered in the “cassette ID” field of the patient list is displayed as shown in FIG. An engineer, for example, takes three cassettes and moves to the imaging room to take an image of the patient. Thereafter, the photographed cassette is read by a reader. The reading device reads the cassette ID attached to the inserted cassette, attaches it to the image data, transmits the cassette ID, and finally the correspondence between the imaging ID (patient ID) and the generated image data is attached. . The generated image data is transmitted to the console where the technician has selected the photographing ID and displayed on the console. At this stage, the imaging positioning is confirmed. If the positioning is poor, the imaging is performed again, and it is also determined whether or not to apply density and contrast correction and frequency enhancement processing. Thereafter, the image is stored in a server waiting for interpretation (waiting for diagnosis). An image interpretation doctor extracts and displays an image related to a predetermined patient from an image stored in the image interpretation waiting server on a workstation in an image reading room (often equipped with a high-definition monitor for a viewer function). (Diagnosis) is performed.

In a system used in such a large-scale facility, for example, whether the imaging performed on the patient is a simple imaging or a contrast medium imaging, the information that affects the insurance score calculation, such as the imaging ID of the patient By registering a cassette ID or the like and associating a patient with a captured image, all information can be linked together and managed in a RIS / HIS server or the like. In general, DICOM (Digital Imaging and Communications in Machine) is adopted as a standard protocol for linking information between a plurality of apparatuses in a hospital. DICOM defines the format (format) of data to be transmitted and received, and when a device that does not support DICOM is connected to a network in a hospital, it is converted to DICOM format by a conversion device. (For example, refer to Patent Document 4).

  However, according to the present inventors' investigation, 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, in many cases, a doctor who examines a patient is alone. Yes, the number of installed image generation devices is also small. In many cases, the assistant positions the patient, and the doctor controls the X-ray exposure switch in response to the positioning completion from the assistant, or the doctor himself performs all operations including the patient positioning.

  Also, for example, in the case of a large-scale facility, it is assumed that the patient has to travel between multiple floors in the facility after taking a picture until receiving a doctor's diagnosis. In some cases, since the facilities are small, the distance traveled by the patient after taking a picture until receiving a doctor's diagnosis is short.

  Under such circumstances, it is difficult to consider that the captured image is mistaken for that of another patient. If a system similar to that of a large-scale facility is used, the procedure becomes complicated and the medical efficiency is poor.

  In addition, in order to generate imaging order information such as patient information and imaging condition information of a patient in advance and associate the imaging order information with a captured image, each device is connected to a basic system such as RIS / HIS. However, it is costly to construct such a system, and means to ensure data consistency with the core system is necessary, which is a burden for small-scale facilities. There is also a problem.

In the present embodiment, the inspection device 4 is a device compliant with the DICOM standard, and transmits inspection data to the control device 3 in the DICOM format.
For example, the inspection device 4 attaches the above-described UID to the acquired inspection data.
Although not shown, the inspection apparatus 4 is also provided with input operation units each including a keyboard, a touch panel, and the like. The input operation unit is a device for inputting patient information of a patient to be examined. When the patient information is input from the input operation unit, the inspection device 4 adds the input patient information to the inspection data together with the above-described UID, and transmits it to the control device 3. Note that the configuration of the input operation unit is not limited to that shown here. For example, a card reader that reads information written on the card by inserting a card or a barcode reader that reads a barcode may be used. .

The reception device 5 is a computer device for performing registration, accounting, insurance score calculation, etc. of patients who come to the hospital. , A display unit configured by a CRT, an LCD, and the like, and a communication unit (none of which is shown) that controls communication with each device connected to the network 6. When the reception device 5 is instructed to display the reception input screen from the input unit, the reception device 5 displays a reception input screen (not shown) on the display unit by software processing in cooperation with the CPU and the program stored in the storage unit. When reception information (reception number + patient name) is input by the input unit via the reception input screen, a patient information list of the received patients is created (updated) and stored in the storage unit. It transmits to the control apparatus 3 by a communication part according to a patient list transmission request.
In the control device 3, the patient information list transmitted from the receiving device 5 is displayed, and the patient information is input by clicking and selecting the patient targeted by the doctor from the patient information list with the mouse or the like of the input unit 34. It is possible. This simplifies the input operation by the doctor, prevents typing errors and shortens the time compared to the unfamiliar keyboard input operation by the doctor, and improves the data consistency and diagnostic efficiency of the entire small-scale facility. It becomes possible.

At the time of the patient visit, the reception device 5 receives the reception number and the patient name, but at the time of the end of the medical treatment (end of the reception process), the reception device 5 also provides information such as sex, date of birth, and age. As a result, the information is input, and this information is used for management of patients who are examined at a small-scale facility.
For example, it is possible to reduce the load on a doctor who is unfamiliar with keyboard operation by using it for patient information input by a doctor by displaying the patient list described above. The image data generated by the image generation device 2 and the inspection data acquired by the inspection device 4 are also associated with the patient information input at the reception device 5 and managed.
Although patient information can be input also in the image generation apparatus 2 and the inspection apparatus 4, the input patient information is simple information such as a reception number and is not used for the management described above.

  Next, the flow of diagnosis for one patient in a small-scale facility to which the small-scale diagnosis system 1 is applied will be described.

  When the patient comes to the hospital, a reception number tag is given to the patient at the reception 11, and the reception device 5 receives patient information such as the patient reception number and patient name (reception input) received by the operation of the input unit. Done. In the reception device 5, when a patient reception number and patient information are input, a list of patient information (patient information list) is generated (updated) and stored in a predetermined area of the RAM. The patient information list is generated, for example, when the first patient of today is received and input, stored in a predetermined area of the RAM, and updated to a new patient information list every time the next patient is received and input.

  When the patient to whom the reception number is assigned moves to the examination room 13, an inquiry is performed by a doctor, and imaging and examination to be performed are determined.

  When it is determined that the affected area needs to be imaged by the interview, the imaging operator who performs imaging such as a radiographer or nurse takes the image generation apparatus 2 (ultrasound diagnostic apparatus 2a, endoscope) The patient is taken in front of the mirror device 2b or CR device 2c), and the patient's diagnosis target part is imaged as a subject, and image data of the captured image is generated. For example, when the image generating device 2 is the CR device 2c, the photographing device 22 performs photographing, the cassette that has been photographed by the photographing device 22 is set in the reading device 23, and the radiation image recorded in the cassette is read. In the image generation device 2, patient information is input, imaging, and image data are generated in accordance with the operation of the imaging operator, and incidental information including the patient information input to the generated image data and the above-described UID is included. It is attached and transmitted to the control device 3. Note that it is preferable that the patient information input by the imaging operator from the image generating apparatus 2 is not a name but a reception number that is individually assigned to each patient because the input operation of the imaging operator is simplified.

  For example, when it is determined by an inquiry that blood pressure, body temperature, an electrocardiogram or the like is necessary, a doctor or a nurse performs an examination on the patient with the examination apparatus 4. In the inspection apparatus 4, patient information is input and inspected according to the operation of the doctor or nurse, and the incident information including the patient information input to the obtained inspection data and the above-mentioned UID is attached to the control apparatus. 3 is transmitted. In addition, it is preferable that the patient information input by the doctor or nurse from the inspection apparatus 4 is not a name but a reception number that is individually assigned to each patient because the input operation is simplified.

  When the imaging and the examination are completed, the doctor displays and references the photographed image received from the image generation device 2 and the examination result received from the examination device 4 in the control device 3 to diagnose the patient.

  The above is a rough flow when examining one patient. The image data generated by the image generation device 2 and the inspection data acquired by the inspection device 4 are associated with patient information in the control device 3. Here, the control device 3 is for the doctor to display the patient's captured image and the examination result for diagnosis, so during the patient's examination, the past or today's captured image regarding the patient to be examined And inspection results are displayed.

  For example, the captured images and the examination results acquired today regarding the patient to be examined are displayed on a medical summary screen 351, a captured image display screen 352, and the like.

  FIG. 4 shows an example of the medical summary screen 351. The medical treatment summary screen 351 is a screen that displays a list of photographing and examinations performed on a patient in time series when patient information of a patient to be examined is input by the input unit 34. The medical summary screen 351 includes patient information 351a, a time axis 351b, a medical summary display area 351c, an up scroll button 351d, a down scroll button 351e, and the like. In the medical summary display area 351c, thumbnail images A1 of images taken for the patient to be examined are classified and displayed for each image generation device 2 in correspondence with the time axis 351b. In addition, an icon (hereinafter referred to as a test icon) A2 indicating that a test result has been acquired is displayed at the position corresponding to the date on which the test data on the time axis 351b is acquired in the medical care summary display area 351c. Each item is classified and displayed. The information on the screen shown in FIG. 4B is information that follows the information on the screen of FIG. 4A, and the down scroll button 351e is pressed a predetermined number of times (predetermined time) from FIG. 4A. Is displayed. When the thumbnail image A1 is pressed by the input unit 34, a captured image display screen 352 for displaying a captured image corresponding to the pressed thumbnail image is displayed. When the inspection icon A2 is pressed by the input unit 34, the inspection data corresponding to the pressed inspection icon can be reproduced.

  FIG. 5A shows an example of the captured image display screen 352. The captured image display screen 352 is a screen for a doctor to perform image diagnosis. In the present embodiment, one thumbnail image of the thumbnail images A1 of the captured images displayed on the medical summary screen 351 is an input unit. This is a screen that is displayed when it is selected (pressed) by the button 34.

  Here, the doctor inputs the patient information of the patient to be examined in the control device 3 at the time of the inquiry and displays the patient's medical summary screen 351 and the photographed image display screen 352, and the past photographed image, the examination result, and the current patient. Since the number of shots, the shooting direction, and the like are determined based on the state of the camera, the shooting person is requested to take a picture or the examination is performed. A patient (that is, a patient for whom patient information is input) and the patient of the received image data or examination data must be matched.

  Therefore, the control device 3 executes the patient information associating process shown in FIG. 6, and the patient information (the medical summary screen 351 and the image data received from the image generation device 2 and the examination device 4 is input). The patient information input to display the captured image display screen 352 is automatically associated with the image and stored. As a control mode at this time, the control device 3 has a first control mode and a second control mode. The first control mode is a mode in which all the image data received from the image generation device 2 after the patient information is input is stored in the image DB 38 in association with the input patient information. The second control mode determines whether or not it is possible to associate the received image data with the input patient information based on the incidental information of the image data received from the image generation device 2 after the patient information is input. In this mode, the received image data is stored in the image DB 38 in association with the input patient information only when it is determined that the association is possible.

  The control mode can be set by the user via a mode setting screen 353 displayed by a predetermined operation of the input unit 34. As shown in FIG. 7, the mode setting screen 353 displays a button 353a for instructing the setting of the first control mode and a button 353b for instructing the setting of the second control mode. Yes. When the button 353a is pressed with the mouse or the like of the input unit 34, the CPU 31 sets the first control mode as the control mode. When the button 353b is pressed with the mouse or the like of the input unit 34, the CPU 31 sets the second control mode as the control mode. The control mode setting information is stored in the storage unit 33. That is, a mode setting unit is realized by the input unit 34 and the mode setting screen 353.

  In addition, in the control apparatus 3, after completion | finish of a diagnosis, the association | correlation offline which performs the correlation with the data received manually and patient information is also possible. For example, an offline association can be set by clicking and checking the “offline” check box 353c of the mode setting screen 353 with the mouse of the input unit 34 or the like. If the offline association is set, the patient information association process shown in FIG. 6 is not executed, and the image data and examination data received from the image generation apparatus 2 and the examination apparatus 4 are stored in the temporary storage unit 331. The

  Hereinafter, the patient information association processing will be described with reference to FIG. The process is stored in the CPU 31 and the storage unit 33 when a predetermined operation for instructing display of a patient information input screen (not shown) for inputting patient information of a patient to be examined is input. This process is realized by software processing in cooperation with a patient information association processing program. The control means is realized by executing the processing.

  First, a patient information list transmission request is transmitted to the accepting device 5 via the communication unit 36, and the patient information list data is acquired from the accepting device 5. Based on the acquired data, the patient information is input to the display unit 35. A screen is displayed (step S1). Here, although not shown, the patient information input screen displays a list of patient information received today, and the doctor clicks and selects the patient information of the patient to be examined by the mouse of the input unit 34 or the like. Thus, patient information of a patient to be examined can be input. That is, a patient information input unit is realized by the input unit 34 and the patient information input screen. The patient information input screen may be configured to input patient information directly from the keyboard. However, as described above, the configuration in which the patient information is selected from the patient information list is preferable because input errors can be prevented and time can be reduced. .

  When patient information of a patient to be examined is input from the patient information input screen by the input unit 34 (step S2), 0 is set to the count value n indicating the number of data reception in this process (step S3), and the image DB 38 The image data stored in association with the patient information input in is extracted, and the examination data stored in association with the patient information input in the examination information DB 39 is extracted and extracted to the display unit 35. A medical treatment summary screen 351 on which the thumbnail image A1 of the extracted image data and the examination icon A2 of the extracted examination data are displayed is displayed. When a display instruction for the captured image display screen 352 is further input from the medical treatment summary screen 351 by the input unit 34, the captured image display screen 352 is displayed on the display unit 35 (step S4).

  After the medical summary screen 351 or the captured image display screen 352 is displayed, the communication unit 36 receives image data from the image generation device 2 or the I / F 37 receives inspection data from the inspection device 4 and receives it. When the received data (received image data or inspection data) is stored in the received data storage unit 321 (step S5; YES), the count value n is incremented by 1 (step S6). In step S5, when data is not received (step S5; NO), the process proceeds to step S14.

  Next, the setting information in the storage unit 33 is referred to, and it is determined whether the control mode is set to the first control mode or the second control mode. If it is determined that the control mode is set to the first control mode (step S7; first control mode), if the received data is image data, the image data is input in step S2. In the case where the received data is examination data, the examination data is saved in the examination information DB 39 in association with the patient information input in step S2 (step S12). ), The process proceeds to step S14. In step S12, for example, the patient information (aaa) in the incidental information of the received data is overwritten with the input patient information (AAA), so that the received data is associated with the input patient information. . When the medical summary screen 351 is displayed on the display unit 35, the thumbnail image A1 of the received image data or the examination icon A2 of the received examination data is generated and the position corresponding to the time axis of the medical examination summary screen Is displayed.

  On the other hand, if it is determined that the control mode is set to the second control mode (step S7; second control mode), the count value n is referred to, and the received data is input with the patient information in step S2. Whether the data is received for the first time after that (the count n value is 1) or not is determined. If it is determined that the received data is data received for the first time after the patient information is input in step S2 (step S8; YES), the incidental information of the received data is stored in the RAM 32 as preceding incidental information (step S8). S9) If the received data is image data, the image data is stored in the image DB 38 in association with the patient information input in step S2, and if the received data is examination data, The examination data is stored in the examination information DB 39 in association with the patient information input in step S2 (step S12), and the process proceeds to step S14.

  If it is determined that the received data is not data received for the first time after the patient information is input in step S2 (step S8; NO), the data is input in step S2 based on the incidental information of the received data. It is determined whether or not the patient information can be associated (step S10). For example, the incidental information of the received data previously associated with the inputted patient information (preceding incidental information stored in the RAM 32) and the incidental information of the data received this time are compared, and they match. If it is determined that they match, it is determined that the received data can be associated with the patient information input in step S2. If it is determined that the incidental information of the received data does not match the preceding incidental information, it is determined that the association is impossible.

  If it is determined that the received data can be associated with the patient information input in step S2 (step S11; YES), if the received data is image data, the image data is stepped. If the received data is examination data in association with the patient information input in S2, and the received data is examination data, the examination data is saved in the examination information DB 39 in association with the patient information input in step S2. Then (step S12), the process proceeds to step S14.

  If it is determined that the received data cannot be associated with the patient information input in step S2 (step S11; NO), the received data is temporarily stored in association with the number indicating the reception order. The data is temporarily stored in the unit 331 (step S13), and the process proceeds to step S14.

  In step S14, if the instruction to end the patient examination of the patient information input from the input unit 34 in step S2 is not input (step S14; NO), the process returns to step S4. When an instruction to end the input examination of the patient is input from the input unit 34 (step S14; YES), this process ends.

For example, when the control mode is set to the first control mode, as shown in FIG. 8 (a), the received data D1 to D4 are all associated with the patient information AAA input in step S2, It is stored in the image DB 38.
On the other hand, when the control mode is set to the second control mode, as shown in FIG. 8 (b), the data D1 received first and the data D2 attached with the same patient information aaa as the data D1, D4 is associated with the patient information AAA input in step S2, and is stored in the image DB 38. The data D3 in which the imaging operator forgets to input patient information and patient information is not attached (null) is temporarily stored in the temporary storage unit 331 without being associated with the input patient information AAA. In addition, even when patient information (for example, bbb) of another patient photographed by an emergency patient interrupt is attached to the received data, it is stored in the temporary storage unit 331 without being associated with the input patient information AAA. Temporarily saved.

  In this way, if the first control mode is set, all of the image data and examination data received after the input of patient information is automatically stored in association with the input patient information. When there is only one image generating apparatus 2 or when the operation is not performed in parallel for a plurality of patients, it is possible to associate the received data with the patient information. On the other hand, if the second control mode is set, only the data that has been determined to be able to be associated with the patient information that is input based on the incidental information among the received data is input. Since the patient information is associated with the patient information, for example, the patient information that is different from the patient information of the data received in advance, such as when the imaging operator leaks the patient information or when another patient is imaged by the emergency patient interrupt, etc. Corresponding data is not associated with the same patient information, and association errors can be suppressed.

  The image data and examination data stored in the temporary storage unit 331 are associated with patient information displayed by pressing the “untitled” button B7 displayed on the medical summary screen 351 or the captured image display screen 352. On the screen 354, it can be associated with patient information. FIG. 9 shows an example of the patient information association screen 354. As shown in FIG. 9, the patient information association screen 354 includes thumbnail images generated based on image data and examination data stored in the temporary storage unit 331 and examination icons for examination data, and the accompanying information. Correspondingly, the images are displayed in the order of acquisition (imaging) time (time portion of UID), and a patient information list is displayed. In addition, you may arrange and display not the time when these data were acquired (photographing) but the order received by the control apparatus 3 side. Select a thumbnail image or examination icon from the screen, select patient information corresponding to the selected thumbnail image or icon from the patient information list, and press the “Register” button to correspond to the selected thumbnail image The image data to be stored is stored in the image DB 38 in association with the selected patient information, and the inspection data corresponding to the selected icon is stored in the inspection information DB 39 in association with the selected patient information. This also applies to offline association.

  As described above, according to the control device 3 of the small-scale diagnosis system 1, when patient information to be examined is input by the input unit 34, image data stored in association with the input patient information, A medical treatment summary screen 351 or a captured image display screen 352 displaying the examination data is displayed on the display unit 35. When image data or examination data is received by the communication unit 36 after the patient information is input, it is determined whether the control mode is set to the first control mode or the second control mode. When the first control mode is set, all received data is stored in association with the inputted patient information, and if it is determined that the second control mode is set, the reception is performed. Based on the incidental information of the received data, it is determined whether or not the received data can be associated with the input patient information, and the received data is input only when it is determined that the association is possible Stored in association with the patient information.

  Therefore, image data and examination data received when a doctor inputs patient information and sees past images and examination results of the patient to be examined can be automatically associated with the patient information of the patient. Thus, it becomes possible to efficiently associate the patient data with the image data generated by the image generation device 2 and the inspection data acquired by the inspection device 4. In addition, by setting the second control mode, the correspondence between the received image data and examination data and the input patient information is based on the incidental information attached to the received image data and examination data. Since it is determined whether or not attachment is possible and association is performed only when it is determined that association is possible, association errors can be suppressed.

  Further, in the second control mode, the image data and examination data that are not associated with the input patient information are collectively stored in the temporary storage unit 331, so that it is easy to associate the patient information with the image data later. It becomes.

  In addition, the description content in the said embodiment is a suitable example of the small-scale diagnosis system 1 which concerns on this invention, and is not limited to this.

  For example, when it is determined whether or not the received data can be associated with the input patient information based on the incidental information of the received data, the patient information and the preceding incidental information included in the incidental information of the received data It may be determined whether or not the patient information included in the data matches, and if they match, it may be determined that the received data can be associated with the input patient information.

  In the above embodiment, the image generation apparatus 2 has been described as an ultrasonic diagnostic apparatus, an endoscope apparatus, and a CR apparatus. However, the image generation apparatus 2 is not limited to this, and for example, an external appearance of a CT apparatus or a body such as skin. It is good also as a digital camera etc. which image | photographs.
