SURGERY ASSISTANCE DEVICE AND SURGERY ASSISTANCE PROGRAM

摘要

A personal computer (1) comprises a tomographic image information acquisition section (6), a memory (9), and a volume rendering computer (13). The tomographic image information acquisition section (6) acquires tomographic image information. The memory (9) is connected to the tomographic image information acquisition section (6) and stores voxel information related to tomographic image information. The volume rendering computer (13) is connected to the memory (9), samples voxel information in a direction perpendicular to the sight line on the basis of voxel information, and sets a restricted display area and an endoscopic display area acquired by the endoscope and produced by the volume rendering computer (13), and displays these on a display (2).

主权项

1. A surgery assistance device configured to display a simulation image during surgery performed by inserting an endoscope into the interior of a surgical instrument, the surgery assistance device comprising:
a tomographic image information acquisition section configured to acquire tomographic image information; a memory that is connected to the tomographic image information acquisition section and configured to store voxel information related to the tomographic image information; a volume rendering computer that is connected to the memory and configured to sample voxel information in a direction perpendicular to the sight line on the basis of the voxel information; and a display controller configured to set a first display area acquired by the endoscope and produced by the volume rendering computer, and a second display area in which display is restricted by the surgical instrument during actual surgery, and display the first and the second display areas on a display section.
