Patent ID: 7630750

Claim:
A method of computer aided treatment planning, performed on a computer system, the method comprising: acquiring a set of 2D images of a region of a patient to be treated; converting said 2D images to a voxel based dataset of the region; storing at least a portion of the voxel based dataset in a partitioned dataset as a binary space partitioning tree having a plurality of leaf nodes; generating a three dimensional image of the region of the patient to be treated from the voxel based dataset, the region including at least one anatomical structure for which treatment is contemplated; identifying the leaf nodes which are effected by the application of a virtual intervention; applying said intervention to the effected leaf nodes and re-generating the portions of the three dimensional image associated with the effected leaf nodes; determining the effect of said intervention; modifying the intervention for improved treatment results; and navigating within the three dimensional image in the area where the intervention is applied to visualize the results of the intervention.
