Such settings can be acquired from the table as shown in FIG. 6C, for example.

In step S407, the CPU 201 of the medical image processing apparatus 101 acquires patient information such as the patient name, patient ID, examination date, date of birth, age, and sex from the DICOM accompanying information of the medical image data designated in step 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 is performed so that a PDF-format electronic document that can display a three-dimensional organ model is output.
Although the example in which the surface shape data, the layer name, and the layer display color are acquired separately has been shown here, they are output as a file in advance and a digital document is generated from the file and the DICOM incidental information. You may make it used when it is performed. For example, the IDTF format or the VRML format can be used as the format of the file output as a unit.

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