Description

  The present invention relates to a small-scale diagnosis support system that operates according to a diagnosis workflow in a small-scale medical institution.

  2. Description of the Related Art Conventionally, large-scale medical institutions such as hospitals have developed large-scale diagnosis support systems that support a series of workflows from accepting a patient to ending examination and diagnosis (see, for example, Patent Document 1). The workflow is, for example, in the order of (1) patient registration, (2) examination imaging, (3) imaging (confirming the image quality of the imaging image), (4) medical examination (interpretation of the imaging image), (5) accounting, etc. Each work is done in a different place. In the diagnostic system, (1) Patient information registration processing, (2) Digitization of captured images by examination imaging (console function), (3) Image processing for captured images, (4) Interpretation Processing functions corresponding to each work such as display processing (viewer function) of photographed images and (5) accounting processing are distributed to a plurality of terminals, and each terminal is connected to a network and linked.

In the above large-scale diagnosis support system, a plurality of patients are handled in parallel at a place where a plurality of persons such as doctors, engineers, reception operators, and the like are separated. Therefore, in order to prevent the patient and the captured image from being mistaken and to coordinate the work between the workers and the processing between the terminals, instruction information called imaging order information is generated in the step (1). ing. The imaging order information includes patient information related to the patient himself, imaging information related to imaging such as imaging date / time and imaging site, etc., and the patient to be imaged, imaging site, etc. are determined based on this imaging order information. Can do. Further, by storing the shooting order information in association with the shooting image data generated by shooting, each shooting image can be identified and managed comprehensively based on the shooting order information.

  However, in a small medical institution such as a practitioner, the above workflow is often performed by a small number of doctors, nurses, and the like, and a doctor alone often performs all the work. In that case, since the other patients are not handled until the examination is completed after receiving one patient, there is almost no possibility of mistaking the captured image for the patient. Even in such a situation, if the above-described large-scale diagnosis support system is applied as it is, a registration process for issuing imaging order information at the time of reception must be performed, which is complicated. In addition, since the installation space of the system is limited, the above-described large function distributed system is not optimal.

  Further, when treating patients one by one at a clinic or the like, since the captured images are continuously generated one by one, the captured images are sequentially obtained for each patient. Moreover, a doctor often observes a photographed image immediately after that. Therefore, as in the case of the large-scale diagnosis support system, rather than associating the patient with the captured image based on the imaging order information, the doctor associates the captured image with the patient manually while observing the captured image at the time of the examination. It is also possible that the efficiency is better.

  According to the first aspect of the present invention, the captured image can be managed based on the information on the recording time, and the recording data can be managed based on the information on the recording time. Generally, in small medical institutions, there are many cases that are operated in cooperation with a doctor in the examination room and an assistant in the radiography room, and the assistant finishes preparation for radiographing such as setting of the X-ray generator and patient positioning in the radiography room. The doctor tells the doctor in the examination room that X-ray bombing is possible, and the doctor listens to the voice of the assistant ready and pushes the switch for X-ray bombing. There are many styles. Therefore, among the plurality of captured images, when it is unclear when the inspection object is switched, the doctor can reproduce the recorded data at the recording time corresponding to the captured time of the captured image, so that the doctor It is possible to easily determine the timing at which the patient to be examined switches based on the sound.

  According to the second aspect of the present invention, the examination target information can be stored in association with the photographed image by inputting the examination target information for the examination target determined by the doctor, and the examination target information can be captured. Images can be managed.

  According to the third aspect of the present invention, the captured image can be managed by the identification information of the image generating means that generated the data, and the recorded data is identified by the image generating means in the shooting room that recorded the data.

A configuration may be adopted in which a fixed one is applied and wired to an external device via an I / F such as a USB to read data in the memory.

Next, the operation of the diagnosis support system 1 will be described together with a doctor's workflow.
First, referring to FIG. 6, the operation at the time of photographing will be described with a focus on the operations in the CR photographing device 2c and the control device 3, and then the photographed image and the inspection object information are associated with each other in the control device 3 with reference to FIG. The operation at that time will be described. FIG. 6 is a flowchart showing an operation when imaging for one patient is performed, and FIG. 7 is a flowchart showing an operation performed after imaging of all patients is completed.

An imaging assistant such as a nurse performs a recording start operation in order to start recording in the imaging room by the recorder 7 before starting the examination. The recording may be performed separately for the examination time such as the morning examination and the afternoon examination, but it is preferable to perform the recording continuously while the imaging is continuously performed. This is in order to match the shooting and recording time zones.
In the recorder 7, as shown in FIG. 6, the recording in the photographing room is continuously performed from the recording start operation to the recording end operation, and the recorded data is recorded in the memory (step S1).

  And when a patient visits for a medical examination, the reception process of a patient is performed in the reception apparatus 11a. An operator (recipient) hears the patient's name and the like and inputs it to the reception device 11a. The information input at this time is simple enough to identify the patient such as name and sex.

  In the diagnosis support system 1, an examination target list (see FIG. 3) indicating a list of accepted patients is created based on the patient examination target information input in the reception device 11 a. The created inspection target list is transmitted to the control device 3 via the network 6.

  In the control device 3, when the inspection target list is received, the inspection target list is displayed on the display unit 33 under the control of the control unit 31. In the examination object list, as shown in FIG. 3, the names of reception patients waiting for examination are listed together with the reception number. The reception number is a number issued by the reception device 11a for temporarily identifying the reception patient, and is sequentially assigned in the order of patient reception.

The doctor refers to the examination target list displayed on the control device 3 and confirms the first reception number 1, that is, the patient who first received the patient, guides the patient into the examination room, and performs the examination. In addition, the examination and imaging of other patients are not performed until the examination and imaging for one patient are completed.
Then, if there is a need for inspection imaging, the process proceeds to imaging operation in the image generating apparatus 2. Hereinafter, although the case where radiography is performed by the CR imaging apparatus 2c will be described, the same processing is performed when imaging is performed by the other ultrasonic imaging apparatus 2a and endoscope imaging apparatus 2b. Here, it is assumed that imaging of another patient is not performed until imaging of one patient is completed.

  In the control device 3, when receiving the examination target list, the control unit 31 assigns list numbers 1 to m in order from the first patient in the examination target list separately from the reception number. Then, the list number n indicating the current examination target (patient whose examination and examination order has been turned) is initially set to n = 1, and examination target information (patient name, reception number of the patient of the list number n) Information) is acquired from the inspection object list and transmitted to the CR imaging device 2c.

In the CR imaging device 2c, a patient notification screen is displayed based on the examination target information received from the control device 3, and the patient's name and reception number are displayed on the patient notification screen. It is shown that there is.
An imaging assistant such as a nurse confirms the patient to be examined on the patient notification screen, and guides the patient to be examined to the imaging room to perform the imaging operation. At this time, the radiographing assistant speaks, “Starts radiographing for Mr. A”, etc., and informs the doctor in the examination room of information related to the examination subject (the name of the patient to be examined and the fact that imaging is started). During this time, the recorder 7 records the voice of the assistant.

  Thereafter, in the CR imaging device 2c, radiation irradiation is performed according to the operation of the photographer, and radiation imaging is performed. When shooting multiple times, such as changing the shooting direction for one patient, the cassette is replaced and continuous shooting is performed. Thereafter, a plurality of cassettes used for photographing are sequentially loaded into the reading device 23 of the CR photographing device 2c, and reading is performed.

When the imaging work for one patient is completed in this way, the imaging assistant speaks out, "Mr. A's imaging has been completed", etc., and after conveying information about the examination subject to the doctor in the examination room, Guide the patient to the examination room. The recorder 7 records this utterance in the same manner as when shooting was started.
Then, the photographing assistant loads the cassette used for photographing into the reading device 23, and performs a reading start operation via the operation unit 232.

  In the reading device 23, when a captured image is read from the cassette and the data is generated (step S2), the current time is acquired by the control unit 231, and the device ID is read from the storage unit 235, and the image is captured. The time information and device ID information are appended to the generated captured image in the header area. The captured image data with the accompanying information is transferred to the control device 3 via the communication unit 234 (step S3). Since the CR imaging device 2c is configured separately from the imaging device 22 and the reading device 23, there is a time lag between shooting and image generation, but reading is generally performed without taking time after shooting. The CR imaging device 2c handles the image generation time as the imaging time.

In the control device 3, when a captured image is received, various image processes such as a gradation conversion process for adjusting contrast and a frequency enhancement process for adjusting sharpness are performed on the captured image, and then on the display unit 33. The captured image is displayed on the screen.
FIG. 8 shows an example of the display.
On the image confirmation screen d shown in FIG. 8, each captured image d1 subjected to image processing in the control device 3 and an operation bar d2 for performing an operation for changing the image processing conditions are displayed. In addition, input areas d3 to d5 are provided for inputting the receipt number, patient name, and imaging region of the patient who is the examination target of the displayed captured image. Further, a hold button d6 and an examination end button d7 are provided at the lower right of the screen.

The doctor checks the image quality by observing the photographed image and examines the patient. And when confirming each displayed captured image as the captured image of the patient, after inputting the information of the reception number, name, and imaging region by the operation unit 32 in the input areas d3 to d5, the examination end button d7 To operate.
In the control device 3, the inputted information on the patient name and the imaging region is attached to the imaging image as the inspection object information regarding the inspection object and transferred to the server 4 (steps S5; N, S7, S8). In the server 4, the patient name and device ID attached to the captured image are referred to, and the captured image data is stored in the database 5 based on the patient name and device ID.

It is also possible to hold the confirmation once and confirm the photographed image after the examination. In this case, the doctor presses the hold button d6.
In the control device 3, when the hold button d6 is pressed (step S5; Y), the displayed captured image is temporarily stored in the storage unit 35 as a hold image under the control of the control unit 31 (step S6). .

The above is the operation in the diagnosis support system 1 when imaging for one patient is performed.
Next, the operation of the control device 3 when performing the confirmation operation for the hold image will be described with reference to FIG.

When the examination for a certain unit time is completed, such as the morning examination time has ended, the photographer performs the recording end operation of the recorder 7. In the recorder 7, a recording end process is performed in response to the recording end operation.
Thereafter, the photographer extracts the memory in which the recording data is recorded from the recorder 7 and attaches it to the control device 3 or connects the recorder 7 to the I / F 37 of the control device 3 and transfers the data in the memory to the control device 3. Let Further, the device ID of the image generating device 2 in the photographing room where the recorder 7 is installed is input via the operation unit 32.

  In the control device 3, the recording data is read from the memory through the I / F 37 under the control of the control unit 31, and the information of the device ID input through the operation unit 32 is attached to the recording data and the server 4. (Step S11). In the server 4, the recording data is stored in a database and managed so that the recording data can be read based on the recording time and device ID information.

Thereafter, the doctor inputs the device ID of the image generation device 2 when performing a confirmation operation for the held image.
In the control device 3, the control unit 31 reads the data of the reserved image corresponding to the device ID input from the operation unit 32 from the storage unit 35, and displays the image on the image confirmation screen e as shown in FIG. 9 on the display unit 33. (Step S12).
On the image confirmation screen e, each captured image stored in the storage unit 35 as a hold image is switched and displayed one image at a time (an image indicated by reference sign e1 in the figure). At this time, the device ID and the shooting time information e2 and e3 are read from the incidental information of each shot image and displayed on the image confirmation screen e.

  If the doctor can identify the patient of the hold image e1 from the display information such as the imaging time e3 by collating with the examination target list on the image confirmation screen e, the doctor name, reception number, and imaging region are input in the input area e4. Input to e6.

  In the control device 3, when the patient name, the reception number, and the examination target information of the imaging region are input via the operation unit 32 (step S <b> 15), the control unit 31 adds the input information as the examination target information to the hold image e <b> 1. Is transmitted to the server 4 (step S16). In the server 4, the pending images are managed as a database based on the inspection target information.

However, depending on the interval of imaging for each patient, the number of times of imaging for one patient, etc., there are cases where it is not easy to determine the patient of the hold image. An example will be described with reference to FIG.
FIG. 10 is a diagram illustrating captured images continuously captured by the CR imaging device 2c with the device ID “03” for each imaging time in a certain examination time zone. In the figure, the numbers in parentheses indicate the shooting order of the shot images. Here, the shooting image g1 in shooting order 1 (shooting time 9:49:05) and the shooting image g2 in shooting order 2 (shooting time 10:05:30), or the shooting image g3 in shooting order 3 (shooting time 10: 12:00) and the captured image g4 in the imaging order 4 (imaging time 10:30:20) have an imaging interval of 15 minutes or more, so that it can be determined that the patient has been switched.

  However, the captured image g2 in the imaging order 2 (imaging time 10:05:30) and the captured image g3 in the imaging order 3 (imaging time 10:12:00) are taken twice for the same patient from the imaging interval. It is difficult to determine whether the patient is switched or the patient is switched, and the patients of the captured images g2 and g3 are unclear. In such a case, the patient reproduces the recorded data at the photographing time in the photographing room where the CR photographing device 2c having the device ID “03” is installed, and listens to the voice of the photographer in the photographing room. The switching timing can be confirmed. That is, when the patient is switched, the photographer speaks to the doctor in the examination room, the name of the patient to be examined, the start and end of imaging, and this sound should be recorded.

  Therefore, each captured image can be identified on a patient-by-patient basis by comparing the captured time of each captured image with the recording time at which the recording start sound and the recording end sound are recorded. It is also possible to specify the patient by the voice of the patient name. In FIG. 10, the time when there was a voice when shooting was started is indicated by a black arrow, and the time when there was a voice when shooting was finished is indicated by a white arrow. The captured image captured between the black arrow and the white arrow is a captured image for one patient, and the patient of the captured image is identified from the voice of the patient name recorded at the start and end of the imaging. Can do.

When reproducing the recorded data, the doctor operates the recording / reproducing button e7 on the image confirmation screen e. In the control device 3, an input screen for a search keyword for recording data such as the device ID, date, and time zone of the image generation device 2 is displayed in response to the operation of the recording / playback button e 7. The device ID, date, shooting time, etc. of the image generation device 2 that has been shot are input.
In the control device 3, the device ID corresponding to the input device ID, date, and photographing time and the recording data of the recording time are read from the server 4. Then, reproduction is performed by the sound reproduction unit 36 based on the read recording data (step S14).

By reproducing the sound of the recorded data, the doctor identifies the patient with respect to the hold image, inputs the examination object information (reception number, patient name, imaging region) on the image confirmation screen e, and then clicks an OK button e8 for instructing image confirmation. Press.
In response to these operations, the control device 3 associates the inspection object information input to the hold image and stores it in the server 4 (steps S15 and S16), and ends this processing. The hold state of the hold image is canceled by associating the inspection object information, and the server 4 manages the captured image based on the inspection object information.

  As described above, according to the present embodiment, information on the device ID and the photographing time is attached to the photographed image, thereby managing the photographed image. Further, the recording data recorded in the photographing room is attached with the device ID of the image generating apparatus 2 installed in the photographing room, and the recorded data is managed by the accompanying information.

  Then, when associating the examination target information with respect to the hold image, the doctor starts shooting of the photographer uttered at the time of shooting by reading and reproducing the recording data of the record time corresponding to the device ID of the hold image and the shooting time. In addition, it is possible to easily discriminate the timing at which the patient is switched from the sound at the end of imaging. Therefore, the doctor can discriminate the corresponding patient for each of the plurality of held images from the photographing time of the held image and the switching timing of the patient, and the association between the patient and the held image can be performed efficiently and easily. it can.

  Further, since the photographed image and the recorded data are managed by the device ID, the recorded data in the photographing room in which the image generating device 2 is installed can be specified and read by the device ID of the photographed image associated with the inspection target information. it can. Thus, even when the image generation apparatus 2 is distributed and installed in a plurality of imaging apparatuses, the doctor can listen to the sound at the time of capturing the captured image using the apparatus ID as a keyword.

  The recorded data can also be used as a shooting history in each shooting room.

  In the above-described embodiment, information such as the patient name and the imaging region is associated with the captured image as the examination target information. However, the present invention is not limited thereto, and the type of the image generation device 2 that has been imaged with the patient name and Names (for example, types such as “ultrasonic imaging device” and “CR imaging device”, model name “CRT2003”, etc.) may be associated with each other. In this case, a photographed image can be searched using the type and name of the image generation device 2 as keywords.

  Further, in the above description, the case where the name of the patient and the word of the assistant who tells the start and end of the imaging are recorded by the recorder 7 before and after the imaging for one patient is described. However, as shown in FIG. When taking multiple shots with different parts (for example, left breast, right breast), "B ready to take a picture of the left breast" and "Ready to take a picture of the right breast of B." In many cases, the photographed part is specified. In this case, by reproducing the recorded data, the doctor can grasp the patient's name, the start and end timing of imaging, and the imaging site.

  Furthermore, for a captured image obtained by each image generation device 2 in the case of using a plurality of types of image generation devices 2, such as imaging with a CR imaging device 2 c for one patient and then imaging with an ultrasonic imaging device 2 a Even when the inspection object information is associated with each other, accurate association is possible with the recorded data and the inspection object list. For example, consider a case where imaging is performed for patients A, B, and C as shown in FIG. Among these, if the examination target information is associated with the ultrasound image captured for the patient B, the doctor captures the patient B with the CR imaging device 2c by reproducing the recorded data corresponding to the device ID of the CR imaging device 2c. Know the end time. Next, the recorded data corresponding to the apparatus ID of the ultrasonic imaging apparatus 2a is reproduced, and the time when the start of shooting is made immediately after the shooting end time in the CR imaging apparatus 2c is confirmed. It can be determined that the ultrasound image at the imaging time close to the utterance time is an ultrasound image captured for the patient B after the CR imaging device 2c.
