Description

  The present invention relates to a medical information processing apparatus and a program.

  In the medical field, digitization of medical images taken of patients has been realized. Digitized medical images are generated by various image generation apparatuses (modalities) such as a CR (Computed Radiography) apparatus, a CT (Computed Tomography) apparatus, and an MRI (Magnetic Resonance Imaging) apparatus. And the medical image produced | generated by these modalities is utilized according to the various uses of a medical field. For example, the generated medical image is stored in a PACS (Picture Archiving and Communication System for medical application) database, or displayed on a predetermined terminal and used for interpretation diagnosis by a doctor.

By the way, the medical image generated by the above-described modality is generated based on order information registered by RIS (Radiological Information System) or HIS (Hospital Information System). Of the order information, various information that is preferably associated with the medical image is attached to the medical image, and the medical image is transmitted to the PACS or the like together with the additional information.
The order information is medical information composed of patient information related to a patient scheduled to be imaged and examination information related to an examination. The patient information includes a patient ID, name, sex, etc. for identifying the patient to be examined. The examination information includes modality information (for example, CR device), imaging information (for example, X-ray simple imaging), and the like.

  The medical image generated by the modality will be used for storage in the PACS or interpretation by the doctor as described above, but all the generated medical images are necessarily used or optimal for use. Not necessarily. For example, when the modality is a CT apparatus, the number of generated medical images may range from several hundred to 1,000. In such a case, it is not necessary to save and view all the generated medical images in the PACS, and it is more efficient to save and view only the images required for interpretation in the PACS. In this case, in a diagnosis flow in which a large amount of medical images are generated as in the case of a CT apparatus, an extraction operation for extracting medical images necessary for interpretation among the generated medical images is required.

  Even when the number of generated medical images is about several, such as a CR device having a small number of images, the medical images are rarely stored in the PACS immediately after the images are captured. An engineer or the like performs a consistency check as to whether or not the generated medical image is based on the order information, and further performs image processing such as extraction of a medical image necessary for interpretation and gradation processing. In this way, a process for performing a predetermined check and processing on a medical image before interpretation and improving the efficiency of interpretation is called image inspection. Through this image inspection process, a medical image optimal for interpretation is stored in the PACS.

In order for a doctor to perform interpretation efficiently, it is important to quickly process the above-described image inspection. As an apparatus for performing such image detection processing, for example, Patent Document 1 discloses an image detection apparatus that facilitates a series of operations from inspection to diagnosis.
JP 2006-94957 A

By the way, imaging is an important process for improving the efficiency of diagnosis, but it is nevertheless an intermediate process and the contents of the imaging process are shown for medical images stored in PACS or the like. History information is not incidental. Therefore, when a doctor wants to confirm what kind of image processing has been performed on an already-examined medical image, he / she cannot confirm from the already-examined medical image, but has to contact the examiner directly. . However, even if it is attempted to make an inquiry to the imager, the doctor cannot specify who the imager to be inquired of, so that the confirmation work becomes more complicated and the interruption of interpretation becomes longer.
In this case, even if the image inspection is processed quickly, if the subsequent interpretation is hindered, the efficiency of the entire interpretation cannot be improved.

  An object of the present invention is to provide a medical information processing apparatus and a program that can facilitate confirmation of information related to imaging.

  Hereinafter, the configuration and operation of an optimal embodiment of the medical information processing apparatus according to the present invention will be described in detail with reference to the drawings. In this embodiment, an example in which the medical information processing apparatus according to the present invention is applied to an imaging apparatus will be described below. However, the present invention is not limited to this, and may be applied to a terminal such as a PACS or an image display apparatus. .

  FIG. 1 shows a system configuration of a medical image system 100 including an imaging device according to the present embodiment. As shown in FIG. 1, a medical image system 100 includes a RIS 1, a modality 2 (2a to 2c), an image detection device 3, a PACS 4, and an image display device 5 such as a LAN (Local Area Network) and a WAN (Wide Area Network). The communication network N is connected so that data can be transmitted and received mutually.

Hereinafter, each device constituting the medical image system 100 will be described.
The RIS1 is a radiology information system that manages information in the radiology department. When there is no RIS1 or when connection with the RIS1 is not possible, an order system for managing order information may be provided.
The RIS 1 receives the registration of the order information by the operator, generates the order information, and manages the order information with an inspection ID serving as identification information. The order information includes one patient information and examination information related to one or a plurality of examinations. For example, when the examination to be performed on a certain patient is imaging of the chest position by the CT apparatus 2a and imaging of the front of the chest position by the CR apparatus 2b, the examination information included in the order information is two. The RIS 1 transmits the generated order information to the modality 2 specified by the modality information included in the order information, and also transmits it to the imaging device 3.

  In this embodiment, the order information generated by the RIS 1 is transmitted to the modality 2 and the image inspection device 3. However, the order information is generated by the receiving terminal that receives and receives the order information, and the modality 2 and the verification information are received. You may make it transmit to the image apparatus 3. FIG.

  The modality 2 is a medical image generation apparatus that images a patient and generates a medical image and accompanying information. In the present embodiment, the medical image system 100 includes a CT apparatus 2a, a CR apparatus 2b, and an MRI apparatus 2c as modalities 2, but there are various types such as an endoscope apparatus and an ultrasonic diagnostic apparatus. A modality for generating a medical image can be applied.

  The modality 2 captures the patient and generates a medical image thereof according to the order information generated by the RIS1. Then, the modality 2 adds the examination ID, patient information, and examination information of the order information received from the RIS 1 as incidental information to the generated medical image and transmits it to the imaging apparatus 3.

  The medical image and supplementary information transmitted from the modality 2 to the imaging device 3 are transmitted as, for example, a DICOM file having an image part and a header part. A medical image is written in the image part of the DICOM file, and additional information (examination ID, patient information, examination information, etc.) related to the medical image is written in the header part.

  The imaging device 3 receives the order information transmitted from the RIS 1 and also receives the medical image generated by the modality 2. The image inspection apparatus 3 displays the received medical image and accompanying information. Note that items displayed by the imaging device 3 at this time include, in addition to the medical image and the accompanying information described above, a consistency check result between the imager registration unit and the order information and the accompanying information (FIG. 6). reference).

  FIG. 2 shows the internal configuration of the image inspection device 3. As shown in FIG. 2, the image detection apparatus 3 includes a control unit 31, an input unit 32, a display unit 33, a communication unit 34, a RAM 35, a storage unit 36, and the like, and each unit is connected by a bus 37. ing.

  The control unit 31 includes a CPU (Central Processing Unit) (not shown) and the like, reads various programs such as a system program and a processing program stored in the storage unit 36, develops them in the RAM 35, and cooperates with the program. Centralized control of processing operations.

  The input unit 32 includes a keyboard having cursor keys, numeric input keys, various function keys, and the like, and a pointing device such as a mouse, and includes a key pressing signal pressed by the keyboard and an operation signal by the mouse. Is output to the control unit 31 as an input signal.

  The display unit 33 includes, for example, a monitor such as a CRT (Cathode Ray Tube) or an LCD (Liquid Crystal Display), and displays various screens according to instructions of display signals input from the control unit 31.

  The communication unit 34 includes a network interface and the like, and transmits and receives data to and from an external device connected to the communication network N. The communication unit 34 is used to receive the order information from the RIS 1 and the medical image from the modality 2 and transmit the imaged medical image to the PACS 4 or the image display device 5.

  The RAM 35 temporarily stores a work area for temporarily storing various programs, input or output data, parameters, and the like that can be executed by the control unit 31 read from the storage unit 36 in various processes controlled by the control unit 31. Form.

The storage unit 36 includes an HDD (Hard Disc), a semiconductor nonvolatile memory, or the like. The storage unit 36 includes various programs such as a system program executed by the control unit 31, a processing program related to generation of imager information, a processing program related to generation of history information, and data processed by each program, etc. Is memorized.
Note that the imager information is information for specifying the operator, that is, for specifying the imager, and is identification information unique to the imager input by the imager via the input unit 32. As an example of the examiner information, for example, the “name” of the examiner can be cited. The history information is information related to the contents of the image inspection process performed on the generated medical image. Examples of the information related to the contents of the image inspection process include incidental information correction history, image order change history, image detection range extraction history, NG image designation history, image processing history, etc. (see FIG. 4). The history information includes information recorded as the examiner change history even when the examiner is changed in addition to the above.
The storage unit 36 stores a history file. The history file is a file that collectively manages the above-described history information, and is a file that stores all history information generated by a series of image inspection processes.

  The PACS 4 includes an image DB (Data Base) (not shown), and stores the medical image transmitted from the image inspection device 3 and its accompanying information in the image DB. In some cases, the medical image generated by the modality 2 is directly stored in the image DB without using the imaging device 3. Further, in response to a request from the image display device 5, a medical image is read from the image DB and distributed to the requesting image display device 5.

  The image display device 5 is a terminal device such as a PC (Personal Computer) installed for the purpose of displaying a medical image distributed by the doctor from the imaging device 3 or the PACS 4 and performing diagnostic interpretation.

Next, a general operation will be described.
FIG. 3 shows the overall processing flow between the devices constituting the medical image system 100. First, RIS1 registers order information and generates it as an order file (step S1).
In addition, the RIS 1 transmits the generated order information to the modality 2 and the image detection device 3 that are designated for imaging in the order information (steps S2 and S3).

When the modality 2 receives the order information from the RIS1, the modality 2 performs imaging of the imaging region of the patient based on the received order information, and generates a medical image (step S4).
Further, the modality 2 attaches patient information and examination information to the header portion of the generated medical image based on the order information acquired from the RIS 1 (step S5), and the medical image with the accompanying information attached thereto is the imaging device 3. As a DICOM file (step S6).

Upon receiving the order information from the RIS 1 and the medical image from the modality 2, the image inspection device 3 stores the received medical image in the storage unit 36 and displays a list of medical images waiting to be stored in the storage unit 36. (Step S7). The list to be displayed includes incidental information of the received medical image, for example (see FIG. 6).
Then, the image inspection device 3 performs image detection processing in accordance with the image inspection operation of the image examiner (step S8).

Here, with reference to FIG. 4, an image detection process performed by the image detection apparatus 3 will be described. Note that it is not always necessary to perform all of the image inspection processing described below, and only necessary processing is appropriately performed according to the medical image. Further, the image inspection apparatus 3 generates history information when performing an image inspection process described later, and attaches it to each medical image that has been processed. On the other hand, the imaging device 3 also saves the history information in a history file.
The processing described below is performed by the control unit 31 in cooperation with a predetermined program stored in the storage unit 36.

The control unit 31 performs a consistency check between the order information received from the RIS1 and the supplementary information of the medical image received from the modality 2, and displays the result on the display unit 33 (step S41). Based on the result of the consistency check, the control unit 31 confirms the presence or absence of an inspection omission, or performs an operation for correcting incidental information related to patient information and inspection information.
When this processing is performed, the control unit 31 generates history information (information on supplementary information correction history in this processing), and attaches the information on supplementary information correction history to the medical image that has been processed. The incidental information correction history is a history about the correction contents of the incidental information. In addition, the control unit 31 saves the information on the incidental information correction history in the history file.

The control unit 31 performs a browsing order change process so as to facilitate interpretation (step S42). In the modality 2 that generates a plurality of medical images, there are cases in which medical images cannot be generated in the order of easy interpretation in a series of photographing operations. For example, when photographing a total of four medical images of the chests 1 and 2 and the abdominal parts 3 and 4, the order in which they are easy to interpret is as described above. However, for convenience of photographing operation, the photographing order (generation order) may be chest 1, abdomen 3, abdomen 4, and chest 2.
As described above, when the generated order is not suitable for interpretation, the doctor must reorder the received medical images for interpretation, which does not contribute to quick diagnosis. Therefore, the control unit 31 rearranges the medical images so that the order is suitable for interpretation, and changes the order after the rearrangement to the generation order and attaches it to the medical image.
When this processing is performed, the control unit 31 generates history information (image order change history information in this processing), and attaches image order change history information to the processed medical image. The image order change history is a history indicating how the medical image generation order has been changed. In addition, the control unit 31 saves the image order change history information in a history file.

The control unit 31 determines an image detection range for image processing by extracting only medical images necessary for interpretation from among a large number of generated medical images (step S43).
When this processing is performed, the control unit 31 generates history information (in this processing, information on the imaging range extraction history), and attaches information on the imaging range extraction history to the medical image that has been processed. The image inspection range extraction history indicates the presence / absence of extraction processing, and if extracted, is a history regarding the range. In addition, the control unit 31 stores the information on the image detection range extraction history in a history file.

Further, the control unit 31 determines a medical image (hereinafter referred to as an NG image) that is not necessarily required for image interpretation within the imaging range (step S44). The NG image is within the inspection range and is transmitted to the PACS 4, but is not displayed when browsing. The doctor performs a predetermined operation from the image display device 5 when it is deemed necessary to view the NG image. In response to this operation, the PACS 4 transmits an NG image to the image display device 5.
When the control unit 31 selects and sets a medical image that is truly necessary for interpretation, the doctor who has received the imaged medical image can omit complicated work related to interpretation and can efficiently interpret the image.
When this process is performed, the control unit 31 generates history information (in this process, information on the NG image designation history), and attaches the information on the NG image designation history to the medical image that has been processed. The NG image designation history is a history indicating the presence / absence of an NG image. In addition, the control unit 31 saves the information on the NG image designation history in the history file.

Then, the control unit 31 performs image processing such as gradation processing on the selected medical image (step S45).
When this process is performed, the control unit 31 generates history information (image processing history information in this process), and attaches the image processing history to the processed medical image. The image processing history is the history indicating the presence or absence of image processing, for example, the contents of various image processing such as gradation processing and rotation processing. In addition, the control unit 31 saves this image processing history in a history file.
When the control unit 31 performs the above-described image inspection processing and history information generation and storage processing, this processing ends.

Returning to FIG. 3, the processing after step S9 will be described.
After the imager completes the image detection operation, the image detection device 3 associates the imaged medical image (including supplementary information) and the history file with the inspection ID or the like and transmits it to the PACS 4 or the image display device 5 ( Step S9, Step S10).

The PACS 4 stores the medical image received from the image inspection device 3 in the image DB (step S11).
The image display device 5 displays the medical image stored in the PACS 4 or the medical image transmitted from the imaging device 3 on a display unit (not shown) (step S12). The doctor makes an image interpretation diagnosis for the displayed medical image (step S13).

  Here, when a doctor performs an interpretation diagnosis, it may be necessary to make an inquiry to the examiner about the received medical image. For example, the image inspection apparatus 3 extracts only a medical image required for interpretation and transmits it to the PACS 4 or the image display apparatus 5. However, extraction of a medical image required for interpretation is performed by an image examiner, and is not performed by a doctor who actually performs interpretation. Therefore, when the number of medical images necessary for interpretation is not extracted in the imaging apparatus 3 as instructed by the doctor, the doctor makes an inquiry to the examiner and extracts and transmits the medical image necessary for interpretation again. You need to ask them to do it.

  Therefore, in the present embodiment, as shown in FIG. 5, in addition to the history information generation process, the examiner information generation process is executed. Then, the image inspection device 3 transmits history information and image examiner information to the doctor side (PACS 4 or image display device 5) together with the imaged medical image. Thereby, the doctor can easily confirm the contents related to the image inspection processing and the image examiner, and can improve the efficiency of the entire interpretation flow.

Hereinafter, with reference to FIG. 5, a history information generation process executed by the image inspection device 3 will be described. This process is executed in cooperation with the control unit 31 and a predetermined program provided in the storage unit 36.
Further, as a premise of this processing, the imaging apparatus 3 is in a state where it is supplied with power and is in operation and is capable of sequentially receiving order information from the RIS 1 and medical images from the modality 2. A person must log in in order to perform an imaging operation.

  The control unit 31 receives the order information transmitted from the RIS1 and the medical image transmitted from the modality 2 and stores them in the storage unit 36 (step S51). At this time, the control unit 31 stores the order information received first and the medical image received later in association with each other based on the examination ID.

The control unit 31 displays a login screen for inputting login information on the display unit 33, and it is necessary for the examiner to input login information via the input unit 32 when performing image inspection. In the image examination act, the examination contents can be confirmed and corrected, and at the same time, the patient's personal information can be viewed. Therefore, for security reasons, it is preferable that only a specific person (an imager) who is permitted to perform an image inspection can log in to the image inspection device 3.
The login information may be unique identification information that can identify the imager such as the name and ID of the imager. In the present embodiment, the login information is the name of the person who logs in.

  Until the login information is input via the input unit 32, the control unit 31 permits reception of data such as order information and medical images, and prohibits display of the examination screen (step S52; No). When login information is input via the input unit 32 from this state (step S52; Yes), the control unit 31 stores the login information in the storage unit 36 (step S53), and displays an image inspection screen on the display unit 33. (Step S54).

  Here, FIG. 6 shows an example of an imaging screen. When the login information is input, the control unit 31 causes the display unit 33 to display an imaging screen shown in FIG.

In the image examination list portion L, incidental information (examination ID, patient information, examination information, etc.) of the received medical image is displayed. Further, the consistency check result between the order information and the supplementary information of the medical image is also displayed in the imaging list portion L. In the present embodiment, the supplementary information whose consistency check result is inconsistent is added with a color and displayed so that it can be easily visually recognized by the examiner. However, the present invention is not limited to this, and for incidental information whose consistency check results do not match, an identifiable symbol or the like may be added to the head of the list. The image examiner can scrutinize the medical image before being used for interpretation, such as the presence or absence of inspection omission and correction of inconsistencies with the accompanying information based on the consistency check result.
In the image inspection list portion L, an NG list Q for displaying the presence / absence of NG images and the number of NG images is displayed. Thereby, even for an examination that is not displayed in the thumbnail portion T, which will be described later, the doctor can easily grasp the presence and number of NG images. In addition, an imager name list for displaying an imager name may be displayed on the image detection list part L.

In the thumbnail portion T, received medical images are displayed as thumbnails. The images displayed as thumbnails can be selected by the examiner clicking on the supplementary information displayed in the list in the detection list portion L with a mouse or the like. In addition, when the imager performs image processing such as gradation processing on the medical image displayed as a thumbnail, the medical image may be displayed on the full screen by double-clicking the medical image of the thumbnail with a mouse or the like. Then, it may be displayed on the full screen in response to an operation such as double clicking on the incidental information with a mouse or the like. The mode of full screen display displayed at this time will be described later in the description of FIG.
In addition, the NG image P displayed on the thumbnail portion T is displayed with a browsing prohibition display on the NG image P. Such an identification display is not limited to an NG image, and a display such as OK indicating browsing permission may be attached to a browseable image.

  The imager registration unit R displays each unit of an imager fixing / interlocking switching unit R1, an imager name input unit R2, and a photographer name display unit R3. When the examiner changes the examiner to an examiner different from the login information described above, the examiner may input or select identification information such as the name and ID of the examiner from the examiner registration unit R. it can. In the present embodiment, the identification information input or selected by the examiner in the examiner registration unit R is the name of the examiner. Any unique identification information may be used.

The examiner fixing / interlocking switching unit R1 is used to switch between the examiner fixing mode and the examiner interlocking mode.
The examiner fixing mode is a mode in which the examiner can input or select the name of the examiner in the examiner name input unit R2 for registering the name of the examiner. This mode is used when the examiner and the photographer are different persons. When the examiner selects to switch to the examiner fixed mode, the name of the examiner is automatically displayed on the examiner name input unit R2. The name of the examiner displayed at this time is the above-described login information input by the examiner at the time of login. Note that the control unit 31 may default display a preset name of the examiner in the storage unit 36.
The examiner interlocking mode is a mode in which the photographer name is automatically displayed on the examiner name input unit R2. In this mode, the names displayed on the examiner name input unit R2 and the photographer name display unit R3 are the same. The name of the photographer and the name of the examiner displayed at this time are extracted from the supplementary information of the medical image and displayed by the control unit 31.

The examiner name input unit R2 is used to input or select the name of the examiner. The examiner can input the name of the examiner by double-clicking on the examiner name input unit R2 with a mouse or the like, for example. The examiner can click on a predetermined location on the examiner name input unit R2 using a mouse or the like to open a pull-down menu and select the examiner name. The name of the examiner displayed so as to be selectable at this time may be identification information preset in the storage unit 36 in addition to the login information.
When the examiner inputs or selects a new examiner name in addition to the displayed examiner name, the control unit 31 inputs authentication information to the examiner in steps S57 and S58 described later. Request (password authentication).

  In the photographer name display portion R3, the name of the photographer who has photographed with the modality 2 is displayed. The control unit 31 extracts the photographer information from the supplementary information attached to the medical image and displays it on the photographer name display unit R3.

The transmission button S is used when the medical image selected by the examiner is transmitted to the PACS 4 or the image display device 5. The examiner can select the transmission destination of the medical image from the pull-down menu on the transmission button S, and can output the film to an imager (not shown).
Hereinafter, returning to FIG. 5, processing after the examiner registration unit R is displayed on the image examination screen will be described.

  If the person who logged in to the image examination apparatus 3 is the same as the image examiner who is currently examining the image, that is, if the image examiner has logged in (step S55; Yes), the examiner inputs the name of the examiner. The image inspection operation is performed without changing the name (login information) displayed in the part R2. Therefore, the control unit 31 specifies the examiner from the login information and generates the examiner information (step S56).

  On the other hand, when the person who has logged in to the image examining apparatus 3 is different from the image examiner who is currently examining the image (Step S55; No), the name of the examiner is entered from the examiner name input unit R2. Will be entered or selected. At this time, the control unit 31 requests the image examiner to input a password by displaying a password input screen (step S57). The image examiner inputs the requested password via the input unit 32.

When the control unit 31 determines that the password input by the examiner and the password preset in the storage unit 36 are the same (step S58; Yes), the control unit 31 inputs or selects at the examiner name input unit R2. The examiner is identified from the name of the examiner and the examiner information is generated (step S59).
The control unit 31 generates the imager information and performs various types of image processing according to the operation of the imager, and attaches the history information to the medical image to be imaged for each image processing ( Step S60). The contents of the image inspection process and the accompanying history information are as described above with reference to FIG.

  The control part 31 preserve | saves each log | history information of each image detection process (refer FIG. 4) performed by step S60 to the log | history file stored in the memory | storage part 36 (step S61). Then, an image inspection process is performed for a medical image whose image has not been processed (step S62; No).

  When the control unit 31 completes the image inspection process for the received medical image (step S62; Yes), the transmission button S is pressed by the image examiner. When the transmission button S is pressed (step S63), the control unit 31 attaches the examiner information generated in step S56 or step S59 to the medical image that has been subjected to the above-described processing. (Step S64). When the control unit 31 performs the process in step S64, history information and examiner information are attached to the imaged medical image in addition to patient information and examination information.

Then, the control unit 31 transmits the imaged medical image together with the history file to the PACS 4 and the image display device 5 (step S65), and this process ends.
In the present embodiment, the control unit 31 attaches history information to an already-examined medical image and further saves the history information in a history file. However, the present invention is not limited to this. It is good also as saving to a history file, without attaching to.

  Here, FIG. 7 shows an example of a screen of an imaged medical image displayed on the image display device 5. In the present embodiment, the screen example shown in FIG. 7 has the same configuration as when the medical image is displayed on the full screen in the image detecting device 3.

The image display device 5 displays the imaged medical image received from the image examination device 3 on a display unit (not shown). Then, a display indicating the name of the examiner and the presence / absence of the NG image P is overlaid on the displayed medical image. The overlay display indicating the presence / absence of the NG image P indicates that the medical image for which the NG image is designated in the image detection apparatus 3 is not set to display.
Note that other image contents may be displayed in the same manner. For example, the image display device 5 can display the presence / absence of image order change and the presence / absence of gradation processing (image processing) in an overlay manner. In addition, when two or more pieces of inspection contents are displayed in an overlay at the same time, the image display device 5 may display different colors depending on the inspection contents. As a result, the operator can easily grasp the contents of the image inspection process when browsing the medical image on the image display device 5.

FIG. 8 shows the imaging menu J. The above-described overlay display ON / OFF can be switched from the imaging menu J. The image display device 5 pulls down the imaging history I by an operator's operation, for example, clicking on the imaging menu J with a mouse or the like. When the imaging history I is further clicked by the operator, the image display device 5 opens the display switching menu K, and the operator displays whether or not to display the name of the imager and the content of the image overlay on the medical image. Can be switched.
The display switching menu K includes, for example, “analyzer” for displaying the name of the examiner in an overlay, “order history” for displaying the change history of the image order, “NG image” for displaying the presence / absence of the NG image P, gradation And “image processing” for displaying the presence or absence of image processing. When the “original” button is pressed by the operator, the image display device 5 displays the medical image returned to the initial state before the image processing is performed by the image inspection device 3. As a process at this time, a control unit (not shown) of the image display device 5 reads and displays initial settings such as gradation from the incidental information or the history information in the history file.

As described above, according to the present embodiment, the medical image is transmitted with the history information attached to the imaged medical image. Alternatively, the history file is transmitted together with the imaged medical image. As a result, the doctor who has received the imaged medical image can easily confirm the contents of the image examination processing and the image examiner from the accompanying information or the history file. By making these easy to check, doctors can smoothly make inquiries about received medical images and re-request image processing to the examiner, saving labor and efficiency of the overall interpretation workflow. Can be achieved.
In addition, since the contents of the image inspection process can be easily confirmed, the doctor can grasp the experience and tendency of the image examiner. As a result, the imager who performs image inspection in accordance with the doctor's request will gain the trust and high evaluation from the doctor. As a result, the image examiner can perform more rapid and appropriate image detection, and can improve the quality of the image content.

  Further, according to the present embodiment, the NG list Q (see FIG. 6) is displayed on the image detection screen of the image detection apparatus 3. Furthermore, when the medical image is displayed on the full screen by the image inspection device 3 and the image display device 5, an overlay display indicating the presence or absence of the NG image P is displayed on the medical image. Thus, by displaying the history information on the screen, the examiner can grasp the presence or absence of the history information at the time of browsing, and can easily recognize the contents of the history information.

  Further, according to the present embodiment, when the examiner logs in to the image sensing device 3, it is requested to input login information. As a result, only a specific person (an imager) who is permitted to perform image inspection can perform the image inspection operation, and security can be improved. When the input login information is changed and new imager information is input, the authentication information (password) is requested to be input, and further security improvement can be achieved. In this way, it is possible to appropriately update the image examiner who has actually imaged, and this change operation is recorded as history information together with the image sensing process. With the history information that can be confirmed about the information before and after the change operation, the doctor can easily grasp the entire information related to the imaging process.
