Description

  The present invention relates to an output device, a method thereof, a program, and a recording medium, and more particularly to a diagnosis support technique for creating a medical document such as a medical record (medical record) and an image diagnosis report. In particular, the present invention relates to an output technique of a schematic diagram (schema) showing a positional relationship between a human body structure drawn by a doctor on a medical document and a diseased part.

  Before medical documents such as medical records and diagnostic imaging reports were digitized, doctors drawn hand-drawn schemas (schematic diagrams showing the relationship between the human body structure and diseased parts) on medical documents made of paper. It was. In recent years, with the spread of medical information systems such as hospital information systems (HIS) and image storage communication systems (PACS), the digitization of medical documents is gradually progressing. That is, a diagnostic support device is used that can electronically create and display medical documents such as medical charts and diagnostic imaging reports that have been created by a doctor by hand using an information device and can communicate with other medical information systems. I'm starting. HIS is an abbreviation for Hospital Information System, and PACS is an abbreviation for Picture Archiving and Communication System.

  When a medical document is electronically created, a character string can be input relatively easily using a keyboard. On the other hand, in order to draw a figure of an arbitrary shape, a locus drawn by the input device can be input as line drawing information by operating an input device such as a mouse or a tablet. However, in creating a schema, it is necessary to accurately draw a human body structure having a complicated shape. Therefore, it is not easy to draw a figure that satisfies the necessary requirements by a drawing method using a mouse or a tablet.

  Therefore, Patent Document 1 discloses a configuration in which a plurality of schema templates (hereinafter referred to as basic schemas) are stored in advance in the apparatus, and a doctor selects a desired basic schema. By using this configuration, a doctor selects a basic schema and then draws a simple figure indicating a diseased part on the basic schema, thereby drawing a schema (hereinafter, a figure showing a diseased part on the basic schema). , Called schema).

  A configuration is also known in which a desired schema is displayed on a monitor from a plurality of schemas created in this way. Patent Document 2 describes a configuration in which shortcuts such as disease names and syndromes are provided on a screen of an electronic medical record, and a doctor can acquire desired information by selecting these shortcuts.

  However, the conventional configuration has the following problems.

  The configuration described in Patent Document 2 calls a schema diagram from a shortcut associated with a disease name or the like. In order to call a desired schema diagram from a plurality of schema diagrams, a doctor designates a disease name or the like. There must be. Here, since there are many disease names that can be specified, in the conventional configuration, it is troublesome to call a schema diagram by specifying a disease name.

  Further, in the case of a schema having time-dependent information or dynamic information, when displaying the schema on the monitor, the information can be switched and displayed, so that the doctor can confirm a plurality of information. However, since there are many schemas to be displayed, it is troublesome for a doctor to select a schema to be displayed.

<< First Embodiment >>
(Medical diagnosis support system)
FIG. 1 is a diagram illustrating a device configuration example of the medical diagnosis support system according to the first embodiment. In FIG. 1, the (medical) diagnosis support apparatus 1 includes a control unit 10, a monitor 104, a mouse 105, a keyboard 106, and a printer 107. The control unit 10 includes a central processing unit (CPU) 100, a main memory 101, a magnetic disk 102, and a display memory 103. Then, when the CPU 100 executes the program stored in the main memory 101, various controls such as communication with the medical imaging device 5 and the database 3 and overall control of the medical diagnosis support apparatus 1 are executed.

  As shown in FIG. 1, the medical diagnosis support apparatus 1 is connected to a medical image imaging apparatus 5 that can capture an image of a subject. Examples of the medical image capturing apparatus 5 include an X-ray CT apparatus, an MRI apparatus, a US apparatus, an X-ray apparatus, and a nuclear medicine apparatus. The medical diagnosis support apparatus 1 is connected to a medical image database 3 for storing medical images captured by the medical image capturing apparatus 5 and medical examination data including information necessary for diagnosis support processing. It may be configured to acquire a medical image or the like.

  The CPU 100 mainly controls the operation of each component of the medical diagnosis support apparatus 1. The main memory 101 can be realized by a RAM (Read Only Memory), stores a control program executed by the CPU 100, and provides a work area when the CPU 100 executes the program. The magnetic disk 102 stores an operating system (OS), device drivers for peripheral devices, various application software including programs for performing diagnosis support processing, which will be described later, and the like. The display memory 103 temporarily stores display data to be displayed on the monitor 104. The monitor 104 is, for example, a CRT monitor or a liquid crystal monitor, and displays an image based on data from the display memory 103. The mouse 105 and the keyboard 106 are used for a pointing input and a character input by the user, respectively. The printer 107 prints sentences and images. The above components are connected to each other via a common bus 108 so that they can communicate with each other.

  In the present embodiment, the medical diagnosis support apparatus 1 can read medical image data and the like from the medical image database 3 via the LAN 4. Alternatively, a storage device such as an FDD, CD-RW drive, MO drive, ZIP drive or the like may be connected to the medical diagnosis support apparatus 1 so that medical image data or the like is read from these drives. Alternatively, a medical image or the like may be acquired directly from the medical image capturing device 5 via the LAN 4.

(Diagnosis support processing)
Next, how the control unit 10 controls the medical diagnosis support apparatus 1 will be described with reference to the flowchart of FIG. FIG. 2 is a flowchart showing the flow of the diagnosis support process executed by the diagnosis support apparatus 1. 2 is realized by the CPU 100 executing the program stored in the main memory 101. Hereinafter, the flow of processing when medical image data including a captured image of a diseased part or the like is read, the user creates a schema, and prints the electronic medical record on which the schema is described will be described. Hereinafter, a case where a doctor operates this configuration as a user will be described.

  In step S <b> 201, the CPU 100 performs processing for inputting desired medical image data to the medical diagnosis support apparatus 1 in accordance with an input from the mouse 105 or the keyboard 106. Hereinafter, the medical image data input in step S201 is referred to as a diagnostic image. In the image data input process, for example, as described above, the CPU 100 receives the medical image data as a diagnostic image from the medical image database 3 that stores the captured medical image data via the LAN 4. Alternatively, the CPU 100 reads image data as a diagnostic image from a storage device connected to the medical diagnosis support apparatus 1, for example, various storage media such as an FDD, a CD-RW drive, an MO drive, and a ZIP drive.

  In step S <b> 202, in accordance with a doctor's command input, the CPU 100 reads into the main memory 101 a medical document in which a medical image, supplementary information, a medical examination progress, and the like are described. The reading of the medical image and the accompanying information can be realized by the CPU 100 communicating with the medical image database 3 via the common bus 108 and the LAN 4 and receiving the desired medical image and the accompanying information. Alternatively, the CPU 100 can be realized by reading a desired medical image and supplementary information from an external storage device connected to the diagnosis support apparatus 1.

  Here, the supplementary information is information indicating, for example, the type and imaging conditions of the imaging device that captured the medical image, the human body part that is the imaging target, and the like, and can be provided in a text format, for example. This supplementary information is generated by the medical image capturing device 5 and is stored in the medical image database 3 in association with the medical image simultaneously with the image capturing.

  Regarding the handling of this information, standardization of a communication protocol dedicated to medical image data that enables interconnection of image diagnostic apparatuses and medical information servers manufactured by different manufacturers, as well as a medical information viewer, has been carried out. For example, the DICOM (Digital Imaging and Communications in Medicine) standard has been established.

  Reading of the medical document can be realized by the CPU 100 communicating with the medical document database 2 via the common bus 108 and the LAN 4 and receiving a desired medical document. Here, the received medical document is the last saved medical document for the follow-up patient at the time of the previous diagnosis, and for the new patient a new patient attribute such as the patient's name, gender and date of birth is entered. It is a medical document.

  The CPU 100 reads the read diagnostic image and medical document from the main memory 101 and outputs them to the monitor 104.

  In step S203, a schema creation selection is received from the doctor. If the doctor selects creation of a schema (YES in step S203), the process proceeds to step S204, and the CPU 100 presents a basic schema selection list to the doctor. If the doctor does not select creation of the schema (NO in step S203), the process proceeds to step S206.

  In step S204, selection of a basic schema is received from a doctor. The CPU 100 reads a large number of basic schemas stored in the magnetic disk 102 and displays a schema list as a list on the monitor 104.

  The basic schema stored in the magnetic disk 102 is assigned a basic schema group and an identification name and an identifier that can identify each basic schema. Here, the basic schema group is divided into units such as head / neck, lung, heart / circulatory organ, digestive system, bone, ear / nose / throat. The groups are hierarchical. For example, in the case of lungs, the groups are further divided into units such as lungs (front) and lungs (sides). The identification name is for the doctor to distinguish the type of basic schema, and is the names “lung (front)” and “head (left side)”. The identifier is for the CPU 100 to identify the type of basic schema, and is represented by bits such as “100000000001” and “001000100100”. Using this identifier, the CPU 100 identifies the basic schema group and type. Here, the identifier is not limited to the number of bits or the bit expression, as long as the CPU 100 can distinguish the type of basic schema.

  The schema list output to the monitor 104 may be a list in which identification names of basic schemas are listed, or a list in which thumbnail images (reduced images having a size suitable for list display) of basic schemas are listed. . Alternatively, the schema list may be grouped hierarchically and displayed sequentially from the list of the highest hierarchy. When the doctor selects a desired basic schema from the schema list displayed on the monitor 104, the CPU 100 reads the selected basic schema into the main memory 101.

  In addition, as a basic schema selection method, the CPU 100 automatically selects basic schema candidates from the DICOM standard read in step S202, presents the candidates to the doctor, and the doctor selects from the candidates. May be. For example, the CPU 100 reads information related to the imaging device and the imaging region from the DICOM standard. When the imaging device is CT and the imaging site is the chest, as shown in FIG. 3, the basic schema candidates are coronal images 31 to 33, axial images 34 and 35, and sagittal image 36, which are orthogonal three cross-sectional images. Basic schemas with different degrees are candidates. When the imaging device is a simple X-ray, the basic schema candidates are the front images (coronals) 31 to 33. FIG. 3 is a diagram illustrating an example of basic schema candidates.

  Next, in step S205, the doctor performs a process of inputting a point of interest on the diagnostic image to the basic schema. That is, a process of receiving a setting of a point of interest on the diagnostic image in the basic schema from the doctor is performed.

  In this process, for example, a doctor uses a mouse 105, a keyboard 106, a pen tablet (not shown), or the like to designate a place where a disease is suspected on a diagnostic image as a basic schema, and inputs the information to the diagnosis support apparatus 1. This can be realized by performing processing. The point of interest can be specified by, for example, selecting a method of inputting image coordinates as points, a method of inputting a set of image coordinates or information replacing the region information on the image, or selecting a large number of templates stored on the magnetic disk 102. It can be executed by the method of inputting the Further, the point of interest designated by the doctor is not limited to one point for the diagnostic image, and inputs such as a plurality of points or a plurality of regions may be received for the basic schema. For example, there may be a case where a part that is considered to be a primary disease of a certain disease and a part that is suspected to be metastasized are designated as attention parts. In this case, it is possible to perform a process of sequentially storing a plurality of designated attention points so that the doctor can input a command indicating that the input of the attention points has been completed.

  As shown in FIG. 4, the locations designated as the basic schema are stored separately in layers 41 to 43 by date or operation. FIG. 4 is a diagram for explaining the basic schema and layers. A layer means a transparent image provided virtually. In this embodiment, a schema is created by superimposing a layer drawn by a doctor on a basic schema. For example, when a new schema is created, the CPU 100 creates a layer simultaneously with the reading of the basic schema 32 and stores a point of interest designated by the doctor on the layer. Similarly, when a new point of interest is designated for an existing schema created in the past, the CPU 100 creates a layer simultaneously with the reading of the existing schema and stores the point of interest designated by the doctor on the layer. To do. By combining these basic schema 32 and layers 41 to 43, a schema 45 can be created.

  A layer may be created not only when a basic schema is read and when an existing schema is read, but a new layer may be explicitly added at an arbitrary time desired by a doctor. Thereby, a plurality of different information can be stored on one basic schema.

  In the present embodiment, an example of processing in which selection of a basic schema is received in step S204 and a point of interest is specified for the basic schema selected in step S205 has been described. However, the method of designating a point of interest for the basic schema is not limited to this. For example, the CPU 100 may automatically select and display the basic schema in response to the doctor specifying the attention location on the diagnostic image, and the doctor may specify the attention location on the basic schema. . Alternatively, the CPU 100 automatically selects a basic schema in response to the doctor designating a spot of interest on the diagnostic image, and the CPU 100 automatically designates the spot of interest on the basic schema. Good. At that time, the CPU 100 aligns the diagnostic image with the basic schema, and associates the attention location designated by the doctor on the diagnostic image with the attention location designated in the basic schema.

  In step S <b> 206, the selection of the schema output format is received from the doctor, and the CPU 100 selects the schema to be output in the output format selected by the doctor and outputs it to the monitor 104. In this process, selection of whether to output a plurality of schemas statically or dynamically is accepted. In addition, when outputting a plurality of schemas statically, the display area of the monitor 104 is divided and a plurality of schemas are displayed at the same time. When dynamically outputting, the schema to be displayed is automatically displayed at a predetermined timing. Switch to display one by one.

  When statically outputting a plurality of schemas to the monitor 104, a screen configuration to be displayed is selected as shown in FIG. FIG. 5 is a diagram illustrating an example of display screen division. Thereby, the maximum display number m of the schema can be set. Here, (a) is a one-screen display, (b) is a divided display, and (c) is an example in which one-screen display and other candidates are displayed as thumbnails. In the case of (c), the schema displayed on one screen and the schema displayed on the thumbnail can be controlled so as to be interchangeable by a drag-and-drop process using the mouse 105.

  A specific processing procedure of step S206 will be described in detail with reference to FIGS. FIG. 6 is a flowchart for explaining the detailed flow of the process in step S206.

  First, in step S601, it is determined whether the same patient has a plurality of schemas. Hereinafter, the number of schemas of the same patient is referred to as the number of schemas. Then, the schema created in the past and the number of layers included therein are counted from the chart information read in step S202. At this time, schemas created for each department such as surgery, internal medicine, and ophthalmology are counted separately. The number of schemas created in the currently diagnosed department is n ′. In step S204 and step S205, the newly created schema and the number of layers included in the schema are counted and totaled with the number of schemas n ′ created in the past. Thereby, the number n of schemas (including the number of layers) created for the same patient can be acquired. In this case, for example, when one layer is included on one basic schema, the count of the number of schemas is 1. When three layers are included on one basic schema, the count is 3. Thus, it can be determined whether or not the same patient has a plurality of schemas. If there are a plurality of schemas for the same patient (YES in step S601), the process proceeds to the next step S602.

  In step S602, the CPU 100 groups a plurality of schemas created for the same patient based on the identifier. Since an identifier is assigned to the basic schema, a group of already created schema image data groups such as lung-lung (front) and lung-left lung (side) are grouped based on the identifier. Can be divided into

  Next, in step S603, the selection of whether to output the schema statically or dynamically is received from the doctor. Then, the CPU 100 branches the process depending on whether the schema is output statically or dynamically. If the schema is output statically (YES in step S603), the process proceeds to step S604, and if it is output dynamically (NO in step S603), the process proceeds to step S606. When the schema is output statically, the setting of the maximum display number m to be output to the monitor is further accepted. First, processing in the case of outputting a schema statically, that is, steps S604 and S605 will be described.

  In step S604, the CPU 100 compares the number of schemas n created for the same patient with the maximum display number m for outputting the schema. The schema number n is acquired in step S601, and the maximum display number m is set in step S603. If the schema number n is larger than the maximum display number m (YES in step S604), the process proceeds to step S605. If the schema number n is less than or equal to the maximum display number m (NO in step S604), the flow in FIG. 6 ends, and the process proceeds to step S207.

  In step S605, the CPU 100 selects m schemas from the n schemas. As a method for selecting m schemas, for example, a schema related to a diagnostic image currently displayed on the monitor 104 can be selected. For example, as shown in FIG. 7, when a chest CT image 71 is being diagnosed, a lung or heart / circulatory system schema related to the chest is selected from a plurality of schema image data groups and displayed. be able to. FIG. 7 is a diagram illustrating an example of schema selection. At this time, since the diagnostic image has DICOM information and the basic schema has an identifier, the CPU can display a schema related to the diagnostic image displayed on the monitor 104 by the doctor. Here, together with the schema, a medical image corresponding to the schema, or a partial area image of a variable portion in the medical image may be selected and displayed simultaneously. Then, the process of FIG. 6 is terminated, and the process proceeds to step S207 of FIG.

  Next, a case where a plurality of schemas are dynamically output in step S606 will be described. As a dynamic output method, for example, a case where a spot of interest is specified in a schema related to the chest and a spot of interest is also specified in a detailed schema of the lung in order to describe more detailed information will be described. First, the entire region image relating to the chest is displayed to show the entire image, and the display is switched to the partial region image of the lung so as to zoom up.

  When there are a plurality of layers on one basic schema, as shown in FIG. 8, the CPU 100 rearranges the schema groups classified in step S602 in time series and displays them on the monitor 104 in the schema groups. Select the schema associated with the diagnostic image. FIG. 8 is a diagram illustrating an example in which a plurality of schemas are dynamically output. Then, the CPU 100 outputs the selected schema to the monitor 104 by switching the layers in time series on the basic schema 32 at a predetermined time interval t as shown in FIG. Then, the date and time when the point of interest is designated for the layer is output together with the layer. Thereby, even if the coordinate position of the attention location is the same region on the layer, the change in the disease is explicitly expressed as to when the change has occurred.

  In addition to displaying only one group in the schema group in time series, not only the schema group created in the same family but also a plurality of schema groups included in the same part are displayed in time series in the hierarchical relation order. You may do it. The same part corresponds to the highest hierarchy in the basic schema list shown in step S204, such as the head / neck, lungs, heart / circulatory organ, digestive system, and the like. For example, regarding the schema group of the abdomen, even if it is a schema created separately by multiple doctors by switching and displaying schema groups created in multiple departments such as internal medicine and digestive organ department, Confirmation can be performed in time series.

  Here, in the above case, selection of a medical image corresponding to the schema or a partial region image of a variable part in the medical image may be received and displayed together with the schema. With the processing described above, the selection of the schema output format is received from the doctor, and the CPU 100 selects the schema for output in the output format selected by the doctor and outputs it to the monitor 104. Then, the process of FIG. 6 is terminated, and the process proceeds to step S207 of FIG.

  Returning to the description of FIG. When the process of step S206 described in detail with reference to FIG. 6 ends, in step S207, a selection as to whether or not to perform schema print processing is accepted from the doctor. When the printing process is performed (YES in step S207), the process proceeds to step S208. When the printing process is not performed (NO in step S207), the process ends.

  In step S208, the CPU 100 determines the output format of the schema and performs print settings. Here, the specific processing procedure of step S208 will be described in detail with reference to FIG. FIG. 9 is a flowchart showing the flow of processing when printing a schema.

  First, in step S901, the CPU 100 determines whether the schema displayed on the monitor is being dynamically output. If it is dynamically output (YES in step S901), the process proceeds to step S902. If it is not dynamically output (NO in step S901), the process proceeds to step S903.

  In step S902, the CPU 100 statically expands the dynamically output schema image data group and selects a schema to be output from the expanded schema image data group. For example, the CPU 100 selects a combination of a basic schema and a layer for each date, and arranges and outputs them in chronological order.

  Alternatively, the CPU 100 may superimpose a plurality of layers on the basic schema and output them in chronological order. For example, the overlapping of a plurality of layers is performed when the exclusive OR A′xorB ′ of the area A ′ of the variable area and the area B ′ of the variable area specified for the layers A and B is equal to or less than a certain threshold T. The layers are displayed on the same basic schema. This may be repeated in chronological order, and if there is a layer N that exceeds the threshold T, the layer N may be displayed superimposed on the new basic schema. Alternatively, the CPU 100 may select and display only a specific schema.

  As a method for selecting a specific schema, an image analysis unit can perform image analysis on a diagnostic image, select a schema created when the amount of change in the fluctuation region is maximum, and output the selected schema together with the diagnostic image. Or as selection of a specific schema, CPU100 may measure the time when the doctor was displaying the schema on the monitor 104 at the time of diagnosis, and may select a schema based on the length of display time.

  In step S903, the CPU 100 displays the schema image selected to be printed on the monitor 104 as a preview screen so that the doctor can check it.

  In step S <b> 904, the CPU 100 reads out the electronic medical record together with the schema from the main memory 101, and transmits the data to the printer 107. In response to this, the printer 107 prints the schema together with the print electronic chart.

  As described above, in the first embodiment, an output device (diagnosis support device) that outputs a schematic diagram (schema) indicating a position of a diseased part in a human body structure to an output unit such as a monitor (display device) or a printing device, A reading process for reading a schematic diagram output from the storage means is performed. Further, the read schematic diagram is selected based on the output format set by the user. Thus, when a plurality of schemas are included in the same patient, a doctor automatically selects a schema according to an output format, so that a doctor can display a desired schema without a troublesome operation, such as a display device or a printing device. Can be output to output means.

In the present embodiment, the display formats that can be set by the user include
A first output format (static output) in which an output area is divided and a plurality of schematic diagrams are output simultaneously.
A second output format (dynamic output) in which a plurality of schematic diagrams are automatically switched at a predetermined timing and sequentially output one by one.
Is included. For this reason, according to the configuration of the present embodiment, it is possible to display a plurality of schemas on an output area with a limited area in an appropriate manner desired by a doctor.

  In the configuration according to the present embodiment, a schematic diagram related to a diagnostic image selected by a user (such as a doctor) is read from the storage unit and output to the output unit. For this reason, according to the configuration of the present embodiment, a doctor selects only one desired diagnostic image, and automatically selects and outputs a plurality of related diagnostic images, thereby favorably examining the doctor. Can help.

  Further, in the configuration of the present embodiment, when selection of the first output format is accepted, several schematic diagrams of predetermined divisions of the output area are read from the storage means and displayed. For this reason, according to the configuration of the present embodiment, it is possible to display a plurality of schemas by utilizing the limited output area of the output unit such as a display device or a printing device.

  In the configuration of the present embodiment, when the selection of the second output format is accepted, a plurality of schematic diagrams are output to the output unit in the order of the imaging time. For this reason, according to the configuration of the present embodiment, the doctor can easily grasp the progress of the diseased part using a monitor with a limited output area.

<< Second Embodiment >>
In the second embodiment, a configuration will be described in which step S605, step S606, and step S902 are changed in the processing procedure in the first embodiment, and a schema is selected based on patient history information.

  In the first embodiment, in step S605, the schema selected in response to the selection of the schema related to the diagnostic image displayed on the monitor 104 is displayed. In step S606, selection of one of the schema groups or a plurality of schema groups included in the same part is accepted. In step S902, selection of a dynamically output schema image data group is accepted by a combination of a basic schema and a layer for each date. However, the embodiment of the present invention is not limited to this form. For example, a schema to be read may be selected based on patient history information. Here, the patient history information is at least one of a diagnosis history, a medication history, and a treatment history.

  In step S605, when selecting an image based on the diagnosis history, the reading unit reads the medical document read in step S202 from the main memory 101, recognizes the words described in the medical document, and acquires the diagnosis history. To do. For example, in the case of follow-up observation, it can be determined that the lesion is progressing when words such as “progress”, “enlargement”, “hypertrophy”, “metastasis” are detected. Further, when the words “reduction”, “recovery”, “decrease”, etc. are detected, it can be determined that the lesion has recovered. When the lesion is progressing, the schema at the time of change (if the basic schema is the same, the layer at that time) is selected. Alternatively, when the lesion has metastasized, the schema before the lesion metastasis and the schema after the metastasis (if the basic schema is the same, the layer at that time) are selected. Here, as shown in FIG. 10, the partial region images 1001 to 1007 of the variable portion on the diagnostic image may be selected and displayed together with the schema. FIG. 10 is a diagram illustrating an example of a schema image to be selected based on a patient's diagnosis history information and a partial region image of the diagnosis image. The partial area images of the diagnostic image may be partial area images 1001 to 1005 with the same modality over time, or may be partial area images 1006 and 1007 captured by a plurality of medical image capturing devices 5 in the same part.

  Further, when selecting an image based on the medication history and treatment history, the CPU 100 reads the medical document read in step S202 from the main memory 101 as shown in FIG. The treatment histories 113 and 114 are acquired. FIG. 11 is a diagram illustrating an example of a partial region image of a schema image and a diagnostic image selected based on patient medication history and treatment history information. The CPU 100 detects the change point of the medication history and the treatment history from the history information. Then, the schema when the medication history or treatment history is changed is detected from the date information, and if there is a schema at the time of change, the schema 1102 at that time and the schemas 1101 and 1103 before and after that are selected. Then, the type of medicine and the treatment method before and after the change are displayed on the monitor 104 together with the schema.

  In step S606, the CPU 100 may acquire not only a plurality of schema groups included in the same site but also the disease name of the site where the disease is detected. Then, a schema of a site where the possibility of metastasis or a causal relationship can be considered may be selected. At that time, it is desirable for the CPU 100 to switch and display the schema in the order of causality. The order of the causal relationship is, for example, when a primary tumor is detected in the chest and then metastasis is detected in the abdomen, as shown in FIG. 12, from the schema 1201 in which the tumor is described in detail in the chest. The display is switched to a schema 1202 in which metastasis is described in the abdomen. FIG. 12 is a diagram illustrating an example of a schema image selected based on patient diagnosis history information.

  In step S902, when the schema image data group that is dynamically output is statically converted and several schemas are selected therefrom, the schema is also selected based on the history information of the patient as in step S605. select.

  As described above, in the present embodiment, the schematic diagram to be read is determined based on the patient history information stored in the storage unit in association with each schematic diagram (schema). As described above, according to the present embodiment, an appropriate schema can be automatically selected according to the patient's medical history, so that the time and effort of the doctor can be greatly reduced. The history information includes information indicating at least one of a patient diagnosis history, a medication history, and a treatment history.

  Moreover, in this embodiment, based on historical information, it determines as a schematic diagram which reads several schematic diagrams which show a series of progress of a disease. For this reason, according to the configuration of the present embodiment, the doctor can check the progress of the patient's disease by browsing the automatically selected schema.
