Specifically, start analysis software such as "heart analysis software" and "liver analysis software" in which organ extraction conditions and layer display conditions are set, and analysis software such as free analysis software in which none of the conditions are set. be able to.

In S202, the CPU 201 of the medical image processing device 101 accepts the designation of the medical image data to be displayed from the user. As described above, the medical image data is generally stored on the PACS (image server), so that the medical image processing device 101 is not limited to the data stored in the medical image processing device. Data stored in an external PACS (image server) or the like can also be specified. Although the example in which the medical image data is specified after the analysis software is started is shown here, the present invention is not limited to this, and the analysis software may be started with the medical image data specified.

In S203, the CPU 201 of the medical image processing device 101 acquires the medical image data specified in S202 from the storage means in which the medical image data is stored.
In S204, it is determined whether the analysis software started in S201 has layer conditions such as organ extraction conditions and display conditions set. If it is set, the process proceeds to S205 to S207, the area is extracted according to the set extraction conditions and set as a layer (S205), and the layer name is set according to the set display conditions (S206) and set. Set the layer display color according to the display conditions.

On the other hand, if it is not set, the process proceeds to S208 to S210, the user accepts the setting of the layer area (S208), the user accepts the layer name setting (S209), and the user sets the layer display color. Accept (S210).

The layer may be extracted automatically, and the name of the layer and / or the display color of the layer may be set by the user. In addition, setting the layer name and setting the layer display color is not indispensable, and if it is not set, the information is not reflected in the output electronic document.

Specifically, it can be determined whether or not the surface shape data is stored in the preset storage means.

When it is determined in S402 that the surface shape data has been created in the past, the process proceeds to S404 without performing the creation process again, and when it is determined in S402 that the surface shape data has not been created in the past. The CPU 201 of the medical image processing apparatus 101 creates surface shape data for each layer set in S205 or each layer set in S208, and stores the surface shape data in a preset storage means location, similarly to S302. By doing so, when the surface shape processing has been performed in the past, the surface shape processing can be omitted at the time of creating the 3DPDF, and the time required for creating the electronic document can be shortened.

In S405, the CPU 201 of the medical image processing apparatus 101 acquires the layer name set in S206 or S209 of the layer displayed by the display button 501. In S406, the CPU 201 of the medical image processing apparatus 101 acquires the layer display color set in S207 or S210 of the layer displayed by the display button 501. Such settings can be obtained from, for example, a table as shown in FIG. 6 (c).

In S407, the CPU 201 of the medical image processing device 101 acquires patient information such as a patient name, a patient ID, an examination date, a date of birth, an age, and a gender from the DICOM incidental information of the medical image data specified in S202.
In S408, the CPU 201 of the medical image processing apparatus 101 uses the surface shape data acquired in S404, the layer name acquired in S405, the layer display color acquired in S406, and the patient information acquired in S407. Control so that an electronic document in PDF format that can display a three-dimensional organ model is output.
Although an example of acquiring the surface shape data, the layer name, and the layer display color separately is shown here, an electronic document is generated from the file and DICOM incidental information by outputting these as a group file in advance. It may be used when it is done. For example, the IDTF format or the VRML format can be used as the format of the file output as a group.

By the above operation, the user can create an electronic document corresponding to the desired medical image data. As a result, the user can confirm the three-dimensional state of the organ even in an operating room where a high-performance computer is not installed, which can be useful for treatment and diagnosis.

In the three-dimensional organ model 905 of the electronic document 902 of FIG. 10, the region of the heart is hidden. Further, the three-dimensional organ model 905 is generated so as to have a set display color for each organ region corresponding to the layer. In this way, by providing the display / non-display for each layer so that the display / non-display can be switched, the user can specify and display or hide only the desired organ model on the electronic document.

The patient information acquired in S407 is displayed in the patient information column 903. By displaying the patient information corresponding to the three-dimensional organ model 905 in this way, it is possible to easily determine which patient's electronic document is.
