Method for computer-assisted planning of path of C-arm in treatment room for patient, involves determining optimal set of paths corresponding to targets, where target is set as value of minimum total risk of collision

摘要

The method involves determining risk volumes for paths of a movable object. The volumes are provided with spatial expansions of a section between each activity volume and each transverse volume of the paths and a probability of occurrence of object types according to the activity volumes. A total risk of collision of a C-arm (1) with objects is determined in a spatial region (R) based on the volumes. An optimal set of paths corresponding to targets is determined using an optimizing process e.g. Newton process, where one of the targets is set as a value of minimum total risk of collision. An independent claim is also included for a computer program product comprising instructions for performing a method for computer-assisted planning of a path of a movable device.
