Description

  The present invention relates to the creation of a schema for a medical information system, and in particular, a system for supporting creation of a radiological interpretation report.

The radiation interpretation report is created by a radiologist with reference to an image taken by a radiologist. In the radiogram interpretation report, a line drawing (schema) indicating an organ or the like may be used to indicate a location that is noticed or has a finding at the time of interpretation.
In the conventional radiation interpretation report creation support system, a schema of several patterns is prepared in advance and a means for allowing the operator to select from among them is prepared, or a function for allowing the operator to draw a schema is provided. The solution is to provide both functions.

  For example, Patent Document 1 describes that a schema can be easily created without using a liquid crystal pen tablet and preparing a special graphic creation device. However, the point that depends on the operator's drawing ability to draw a schema is not considered, and the patent is limited to a patent that improves the operation efficiency of an operator having a certain drawing ability.

Patent Document 2 describes that it is possible to easily select a schema prepared in advance or draw a schema using a means for inputting directly with a pen on a display. However, in order to express an interpretation image from an arbitrary angle or viewpoint, it is necessary to prepare a large number of schemas prepared in advance, and a function for searching for necessary ones from a large number of schemas is necessary. The solution is not listed. Further, although the function of drawing an arbitrary schema on the display is described, the same thing as the above-mentioned Patent Document 1 can be said.

Radiation interpretation report is a diagram that expresses the target part and position with schema as auxiliary means to help understanding because there is a possibility that the contents expressed only by sentences describing the findings etc. may not be transmitted accurately to the interpretation requester May be attached.
When operating on paper, such as when an interpretation report is written on paper, drawing a schema on a margin of the report paper with a hand-drawn or schema-shaped stamp has been conventionally performed.
When introducing a report creation support system, a schema should be registered in advance and selected by an interpreting physician, or a drawing input device such as a tablet should be prepared and a schema drawn on the screen. Is common.

However, in this case, the pre-registered schema may differ from the drawing from the direction that the interpretation doctor wants to express, and there is a possibility that sufficient information for the reference doctor who is the purpose cannot be provided. . In general, use the same perspective direction or tomographic position schema as the image to be interpreted, and comment on it, making it easier to understand the correspondence between the captured image and the report, and the reference doctor's understanding is accurate and efficient I think I can do it.
Moreover, even if input devices such as tablets are enriched, the current situation is that it has not yet provided a schema drawing function that is sufficiently usable as compared to paper operation.

  In order to achieve the object, a storage device for storing 3D schema information generated by a predetermined method, means for creating a 2D schema from surface information or tomographic plane information of the stored 3D schema information, A schema creation device comprising means for transmitting the created two-dimensional schema information to an interpretation report creation support system.

  The apparatus further comprises means for deforming a three-dimensional schema, wherein the creating means creates the two-dimensional schema by deforming the three-dimensional schema information stored in the storage means by the deforming means. 1. The schema creation device according to 1.

  In addition, when creating a 2D schema from 3D schema information, it further comprises means for moving the viewpoint with respect to the 3D schema, the creating means from any direction from the 3D schema information stored by the storage means 2. The schema creation device according to claim 1, which creates a two-dimensional schema.

  When creating a 2D schema from 3D schema information, the image processing apparatus further comprises means for moving a tomographic plane relative to the 3D schema, and the creating means uses an arbitrary tomographic plane from the 3D schema information stored by the storage means. 2. The schema creation device according to claim 1, which creates a two-dimensional schema.

According to the present invention, it is possible to draw a schema from a direction in which an interpreting doctor can easily make a comment, and it is possible to create a report that helps the referring doctor understand.
In addition, according to the present invention, a desired schema can be obtained with a simple operation, and an improvement in report creation efficiency can be expected. In addition, an improvement in service to patients and an improvement in medical quality can be expected.

Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 shows a system configuration diagram of an embodiment of the present invention. In the figure, 101 is a position information input device, 102 is a two-dimensional schema information storage device, 103 is a central processing unit, 104 is a display device, 105 is a schema processing instruction device, and 106 is a report creation support system.

  Fig. 2 shows an example of a schema often used in the interpretation report of X-ray images of digestive system. It is a schema representing the stomach and duodenum and represents the appearance of the digestive organs. In addition to this, a schema that expresses the substance in the organ is also used for an apparatus for taking a tomographic image such as CT or MR.

  FIG. 3 shows the schema change. Change the vertical and horizontal size of the 3D cuboid in which the 3D schema resides, and transform the internal 3D schema. The purpose of this is to make a change suitable for the shape of the organ when the shape of the organ varies depending on the individual difference of the subject.

  FIG. 4 shows a conceptual diagram of creating a two-dimensional schema from various angles of an organ represented by the three-dimensional schema by changing the viewpoint of the three-dimensional schema. In FIG. 3, three types of arrows for viewing the three-dimensional schema are shown as an example.

  FIG. 5 shows an example of creating a two-dimensional schema not only from the outer shape of the three-dimensional schema but also from its tomographic image. Move the tomographic plane and create a tomographic image. This is mainly used to express the substance of the organ. When expressing a CT tomogram of the liver, a schema like such a tomogram is used.

FIG. 6 shows a processing flow of this embodiment. 3D schema information is read from the 3D schema information storage device 102 to the central processing unit 102. On the central processing unit 102, the three-dimensional schema information is developed on the internal memory.
Inside the central processing unit 102, the change in the three-dimensional structure accompanying the change in the aspect ratio is expressed, and the result is reflected on the display device 104 to prompt the operator to confirm. Instruction information such as the degree and direction of deformation is performed from the position information input device 101.

Further, the position information input device 101 moves the viewpoint with respect to the three-dimensional schema to generate a two-dimensional image for viewing the three-dimensional schema from various angles, and the result is reflected on the display device 104 to prompt the operator to confirm.
Further, the position information input device 101 can move the tomographic plane for generating a two-dimensional tomographic image of the three-dimensional schema. The generated tomographic plane is displayed on the display device 104 to prompt the operator to confirm.
Whether the position information input device represents the vertical / horizontal change value, the viewpoint movement, or the movement of the tomographic plane depends on the output of the schema processing instruction device 105.
The generated two-dimensional schema is output to the report creation support system 106, and a system attached to the report can be constructed.
