FIG. 5C is an example in which the position and range of each anatomical part for each body type are indicated by relative positions with respect to height. FIG. 5 (c) shows the relative positions of the start position and end position of each anatomical region with respect to the height in the direction from the top of the head to the tip of the foot, but the direction from the tip of the foot to the top of the head is used as a reference. It may be a relative position. Note that both the direction from the top of the head toward the tip of the foot and the direction from the tip of the foot toward the top of the head are referred to as a head-to-foot direction. As described above, the body shape data may indicate each anatomical region relative to the height by the body shape type. Moreover, you may show by absolute positions, such as the length of the head-and-foot direction of an anatomical site | part for every body type. The relative position and the absolute position of the anatomical site may be an average value or a median value, respectively. In addition, organs included in each anatomical region such as the head and chest may be relatively indicated with reference to the length of the head and chest in the direction of the head and feet. For example, regarding the brain that is an organ included in the head, when the head occupies a range of 20 cm and the brain is in the range of 1 cm to 10 cm from the top of the head, the brain is at a relative position of 1% to 50% with respect to the head. Will be shown.
(2) Operation

  FIG. 6 is a flowchart illustrating an example of the operation of the medical image display apparatus 100 according to the embodiment.

  ST101 in FIG. 6 shows processing in which the image storage unit 21 acquires image data to be displayed on the medical image display device 100 from the medical image management server 200 or the modality device 300.

  ST103 of FIG. 6 shows a process in which the patient information acquisition unit 23 acquires patient information of a patient corresponding to the image data acquired from the electronic medical record server 600. The incidental information of the image data includes the patient management number of the imaged patient. The electronic medical record server 600 is inquired based on the patient management number, and corresponding patient information is acquired. The patient management number may be directly input by the user using the input unit 50.

  ST105 in FIG. 6 shows a process in which the region specifying unit 25 searches the disease-related information database based on the acquired patient information. The disease related information database 63 stores a disease related information table corresponding to patient information. The user may select the disease related information table directly using the input unit 50.

  FIG. 7 is a diagram illustrating an example of a disease-related information table constituting the disease-related information database 63 of the medical image display apparatus 100 according to the embodiment.

  FIG. 7A shows an inquiry table, which is obtained when the inquiry information or the inquiry questionnaire information is selected as the patient information. The inquiry questionnaire information is information acquired in a group medical examination or a medical examination, and is included in the examination information. In the example of the inquiry table shown in FIG. 7 (a), a place where a disease is statistically likely to occur is shown as an anatomical alert part from a lifestyle such as smoking and drinking by sex and age. Therefore, in addition to drinking alcohol and smoking, information such as the anatomical alert part of the large intestine is also included in the inquiry table when the eating habits are mainly carnivorous.

  FIG. 7B shows a case table, which is a table acquired when the inquiry information or the inquiry questionnaire information is selected as the patient information. The case table shows a place where a disease is likely to occur statistically as an anatomical alert part depending on the sex and age, and symptoms such as cough and sputum. Here, the symptom is information based on the patient's physical findings and the patient's complaint. In addition to cough and sputum, blood pressure, pain, bleeding, and the like also correspond to the symptom. The case table includes information for identifying an anatomical alert site from these symptoms.

  FIG. 7C shows a pathological examination table, which is obtained when pathological examination information is selected as patient information. The pathological examination table indicates a site to be an anatomical alert site when abnormal cells or tissues are observed as a result of examining cells and tissues obtained in various organs. For example, as shown in the table of FIG. 7C, the smear test is a test for checking whether the cancer is cervical cancer based on the type and number of abnormal cells contained in the acquired smear. If there are abnormal cells in this test, the anatomical alert site is the uterus.

  FIG. 7D shows a biochemical examination table, which is obtained when biochemical examination information is selected as patient information. The biochemical examination table indicates that, for each examination item such as blood, urine, stool, etc., if an observation is found, it is regarded as an anatomical alert site. For example, as shown in the table of FIG. 7 (d), in the urinalysis, when a finding is found in the amount of protein, the kidney becomes an anatomical alert site.

  FIG. 7E shows a history table, which is acquired when history information is selected as patient information. A medical history is medical history information including a disease that the patient has previously suffered or is currently being treated. The past history table is an anatomical alert part where a disease is likely to occur statistically for a patient suffering from a certain disease, or where a metastasis is likely to occur statistically due to cancer of a certain organ.

  FIG. 7F shows another modality table, which is a table acquired when examination information in another modality apparatus is selected as patient information. The other modality table indicates a part to be an anatomical guard part when a finding is found in the examination image acquired by each modality. For example, as shown in FIG. 7 (f), when findings are found in the lung X-ray examination, it is necessary to examine the lung and bronchus as a close examination. As described above, the other modality table is a table showing, as an anatomical alert part, a place where an observation is found in another modality or a place to be confirmed as a close examination.

  The location to be recognized as an anatomical warning site varies depending on the examination policy or user of each hospital. In addition, statistical information varies depending on academic research. Therefore, the contents of the disease related information table can be updated according to the situation.

  In addition, the patient information includes the same items as the respective items in the corresponding disease-related information table, except for the item indicating the anatomical alert site.

  ST 107 in FIG. 6 compares each row of the disease-related information table corresponding to the patient information retrieved from the disease-related information database 63 with the content of the patient information in the site specifying means 25, and determines the corresponding anatomical alert site. The process to extract is shown.

  FIG. 8 is a diagram illustrating a method for extracting an anatomical alert part from patient inquiry information of the medical image display apparatus 100 according to the embodiment. The image data shown in FIG. 8A is multi-slice image data. In multi-slice image data, the shaded portion indicates supplementary information, and the other portions indicate a plurality of slice images. The incidental information includes a patient management number, body shape information, and imaging conditions. In the part specifying means 25, an extraction process of an anatomical alert part is first performed using the patient information acquired in ST103 of FIG. “XXXX” is stored in the patient management number surrounded by a thick frame shown in the upper part of FIG. The patient management number is assigned a different number for each patient by a combination of numbers and alphabets. This patient management number is transmitted to the electronic medical record server 600, and corresponding patient information is acquired.

  FIG.8 (c) has shown the method of extracting an anatomical alert part from inquiry information, and as shown in FIG.8 (b), the acquired patient information is inquiry information. On the other hand, FIG. 8C shows a disease-related information table stored in the disease-related information database. Since the patient information is inquiry information, the disease related information table to be searched is an inquiry table. In the example of FIG. 8B, the inquiry information includes information on gender (male), age (44 years old), smoking (none), and alcohol consumption (present). The row of the inquiry table corresponding to this information is the second row, and “liver” is described in the column of the anatomical alert part. Therefore, in the multi-slice image data shown in FIG. 8A, the anatomical alert part extracted by the part specifying means 25 is “liver”.

  ST109 to ST113 in FIG. 6 show processing in which the vigilance site determination unit 27 determines in which position and range of the image data the anatomical vigilance site extracted by the site identification unit 25 is projected.

  ST109 in FIG. 6 shows processing for searching the body shape database 61 using the body shape information of the patient included in the incidental information of the image data.

  ST111 in FIG. 6 shows a process of acquiring body shape data that matches the patient body shape information from the body shape database 61. FIG.

  FIG. 9 is a diagram for explaining a method of extracting body shape data corresponding to patient body shape information from the body shape database 61 of the medical image display apparatus 100 according to the embodiment. FIG. 9A shows multi-slice image data of a patient. The table surrounded by the thick frame in the upper part of FIG. 9A shows the patient's body shape information included in the supplementary information of the multi-slice image data. The body shape information of the patient can be acquired from the patient management information included in the patient information based on the patient management number. An inquiry is made to the body shape database 61 using the patient body shape information, and first, the body shape information corresponding to the patient body shape information is searched. The patient's body shape information indicates a height of 170 cm, a weight of 62 kg, an age of 44 years, and a gender indicating male. It can be determined that the body type corresponding to this information corresponds to the body type “2” shown in the upper part of FIG. Furthermore, as the body shape data corresponding to the body shape type “2”, a table showing the relative positions of the respective anatomical sites with respect to the height can be referred to.

  For example, as shown in FIG. 8, when the anatomical alert part is the liver, the body position data corresponding to the body type “2” is used as the relative position of the liver, the start position is 35.3% and the end position. Information of 44.1% can be acquired.

  ST113 in FIG. 6 is a process in which the vigilance site determination means 27 uses the body shape data selected from the body shape database 61 to determine in which position and range of the patient's multi-slice image data the anatomical vigilance site exists. Show. The warning site determination means 27 determines whether the anatomical warning site is a multi-slice from the relative position of the body shape data of the body shape database to the height of the anatomical warning site and the imaging conditions acquired from the incidental information of the patient's multi-slice image data. It is determined which slice image of the image data is projected.

  FIG. 10 is a diagram illustrating a method for determining a slice image corresponding to an anatomical alert site from a multi-slice image of a patient of the medical image display apparatus 100 according to the embodiment. FIG. 10A shows multi-slice image data of a patient, and a table surrounded by an upper thick frame shows imaging conditions. In the example shown in FIG. 10A, the imaging conditions are slice thickness (5 mm), slice interval (2.5 mm), number of slices (680), insertion direction (up and down), start position (top), This is the end position (toe). Here, the slice thickness indicates an imaging range when one slice image is captured. The slice interval is a length between start positions of consecutive slice images. The insertion direction is information regarding the direction in which the slice image is captured. For example, when the patient is inserted from the top of the head, information such as up and down direction, and vice versa, information such as down and up direction is represented. The start position and the end position can be represented by a body part, a distance from the top of the head or the toes, and the like. In the example of FIG. 10, there are a start position (the top of the head) and an end position (toes), which indicate multi-slice image data obtained by whole-body imaging.

  FIG. 10B shows an example in which “liver” is extracted from the disease-related information table as an anatomical alert part. In this case, the alert part determination means 27 receives the input information that the anatomical alert part is “liver”, and acquires the relative position with respect to the height of “liver” from the body shape data that matches the body shape information of the patient.

  FIG. 10C shows a method of determining which position and range of the multi-slice image data corresponds to the slice image of the liver from the relative position with respect to the height of the “liver”. As shown in the lower part of FIG. 10C, the total number of multi-slice image data of the patient is 680. Multiplying the total number by the ratio indicating the start position 35.3% and the end position 44.1% relative to the height of the liver, respectively, the number of slice images onto which the liver is projected is 240 to 300. Numerical values can be calculated.

  When the slice interval indicates a value smaller than the slice thickness, the slice interval is set so that the slices overlap. In such a case, the total number of slices to be apportioned when calculating the anatomical alert site can be determined using the slice thickness and the slice interval. In addition, when the position and range of the anatomical part is indicated by an absolute position such as the length in the cranio-foot direction, the position and range of the anatomical part are determined from the slice thickness and the slice interval of the multi-slice image data. It can be converted.

  ST115 in FIG. 6 shows a process in which the display image generation unit 41 generates display image data that distinguishes the slice image determined by the warning part determination unit 27 from other slice images, and displays the display image data on the display. .

  ST117 of FIG. 6 shows processing in which the data storage unit 65 stores the display image data generated by the display image generation unit 41. The display image data may be stored in the medical image management server 200, the external storage device 500 shown in FIG. 1, or the internal storage device 60 shown in FIG.

  FIG. 11 is a diagram for explaining a method of extracting an anatomical alert part from the patient's past history of the medical image display apparatus 100 according to the embodiment. Similarly to FIG. 8B, FIG. 11A shows patient information acquired by the part specifying means 25. As shown in FIG. 11A, the part specifying unit 25 acquires the past history information as patient information from the patient management number. Using the past history information, the disease related information database 63 is searched, and a past history table which is a corresponding disease related information table is acquired. The acquired history table is compared with the history information of the patient information, and the corresponding row is extracted.

  FIG. 11A shows an example in which the history 1 has high blood pressure and the history 2 has lung cancer. In this case, the past history 1 indicated by a thick frame in FIG. 11A corresponds to the last row of the past history table in FIG. 11B, and “brain, heart” is extracted as an anatomical alert part. The Further, the history 2 shown by the broken line in FIG. 9A corresponds to the first line of the history table in FIG. 11B, and “lung, pharynx” is extracted as an anatomical alert part. . As described above, there may be a plurality of anatomical guard parts selected from the patient information. As described above, even when there are a plurality of anatomical warning parts, the warning part determination means 27 acquires the relative position of each anatomical warning part with respect to the height from the body shape data, and these anatomical warning parts are obtained. The position and range of the slice image on which the warning site is projected can be specified.

  FIG. 12 is a diagram illustrating a first display example of the medical image display apparatus 100 according to the embodiment. FIG. 12 shows a display D1 generated by the display image generating means 41 when the liver is a warning site. The display D1 has a portion for displaying a slice image to be interpreted and a portion for displaying other images. When the slice image to be displayed corresponds to the warning site, a display indicating that the slice image is displayed is output to the portion where the slice image is displayed. The display showing the anatomical warning site enables a user such as a doctor who interprets the image to understand that it is necessary to read the image with caution compared to a location other than the anatomical warning site. Moreover, the user can grasp the progress status by displaying the number of the slice images being displayed out of the total number.

  In a portion where an image other than the slice image to be interpreted is displayed, a reduced image (hereinafter referred to as a thumbnail image) of all slice images is displayed. Each thumbnail image is linked to a corresponding slice image, and by pressing the thumbnail image, the slice image can be displayed in a portion where the slice image to be interpreted is displayed. Also, the thumbnail of the slice image being displayed is distinguished from other thumbnails in which the slice image is not displayed, such as inactivating the link. Further, the thumbnail image of the slice image corresponding to the anatomical alert part is displayed separately from the thumbnail image of the slice image not corresponding to the alert part by providing a frame or the like. In this way, by distinguishing slice images that do not correspond to the anatomical alert part and the anatomical alert part from the thumbnail, it is possible to check how many anatomical alert parts exist as a whole, and the user who performs the interpretation Can do work estimates. In addition, since the thumbnail image is linked to the slice image, it is possible to select and concentrate the interpretation of the anatomical alert part.

  FIG. 13 is a diagram illustrating a second display example of the medical image display apparatus 100 according to the embodiment. FIG. 13 shows the display D2 generated by the display image generation means 41 when the liver is an anatomical alert part, as in FIG. The difference from FIG. 12 is that the display range of the thumbnail image is not the whole but for each part. As in the example shown in FIG. 5C, the body shape data stored in the body shape database 61 includes information on the positions and ranges of all anatomical parts. Therefore, it is possible to calculate which position and range of the multi-slice image other than the anatomical alert part belongs, and thus it is possible to display a thumbnail image for each anatomical part. This display enables interpretation by anatomical part, and reduces oversight by intensively observing specific lesions in the organ corresponding to the anatomical alert part projected on one slice image. be able to.

  In addition, in FIG. 12, it is necessary to search for a warning part from the entire thumbnail image, but in FIG. 13, a list of warning parts is displayed, and the user can grasp at a glance where the warning part is. FIG. 13 shows an example in which lungs and livers are extracted as anatomical alert parts. The display showing the lungs and livers which are anatomical guard parts is displayed in a list, and by linking these displays with the corresponding slice images, interpretation can be started from the selected anatomical guard part. Since it is possible to know the number of anatomical alert parts, it is possible to estimate the amount of work and the time. Furthermore, by displaying a schematic diagram of the whole body and pressing an anatomical part where interpretation is to be started on the schematic diagram, it is also possible to select a body part where interpretation is to be started. In the schematic diagram of the whole body, the range corresponding to the anatomical part being interpreted and the anatomical part not being interpreted can be distinguished and displayed so that the range of the whole anatomical part being interpreted can be grasped. it can. In this way, if the anatomical part to be interpreted can be selected, the work can be performed with inflections on the anatomical warning part that must be interpreted more finely and the anatomical part that roughly confirms the whole. , Can be interpreted efficiently.
