Claim:
1. A non-transitory computer readable recording medium having a trocar port position determination aiding program stored therein, the trocar port position determination aiding program causing one or a plurality of computers to execute: a first setting instruction of setting a point within a three dimensional region represented by the volume data, which are obtained by imaging a subject and are stored in a storage device, as a target point; a second setting instruction of 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 generating and displaying instruction of 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 displaying the plurality of projected images such that they are arranged on a screen in an arrangement that corresponds to the positional relationships among the line of sight vectors, wherein the first setting instruction further comprises: wherein the displaying instruction displays projected images generated for line of sight vectors which have been judged to pass through the obstacle regions or the vicinities thereof in a visually distinguishable manner from projected images generated for line of sight vectors which have been judged to not pass through the obstacle regions or the vicinities thereof, wherein the visually distinguishable manner comprises at least one of emphasizing and marking.
