APPARATUS, AND METHOD FOR AIDING DETERMINATION OF A TROCAR PORT POSITION, AND MEDIUM HAVING A TROCAR PORT POSITION DETERMINATION AIDING PROGRAM STORED THEREIN

摘要

A point within a three dimensional region represented by volume data is set as a target point. A three dimensional angular range having the target point as its apex is set, and a plurality of line of sight vectors directed toward the target point are set within the three dimensional angular range. A plurality of projected images are generated by projecting the three dimensional region onto projection planes perpendicular to the line of sight vectors for each of the line of sight vectors. The generated projected images are arranged and displayed on a screen.

1. A trocar port position determination aiding apparatus, comprising:
a volume data storing section for storing volume data obtained by imaging a subject; a target point setting section for setting a point within a three dimensional region represented by the volume data as a target point; a line of sight setting section for setting a three dimensional angular range having the target point as an apex and for setting a plurality of line of sight vectors within the three dimensional angular ranges directed toward the target point; and a projected image display section for generating a plurality of projected images by projecting the three dimensional regions onto projection planes perpendicular to each of the plurality of line of sight vectors, and for displaying the plurality of projected images such that they are arranged on a screen.
