Abstract:
1. A planning system for planning a cryosurgical ablation procedure, comprising: (a) a first imaging modality for creating digitized preparatory images of an intervention site; (b) a three-dimensional modeler for creating a three-dimensional model of said intervention site, said three-dimensional model being based on said digitized preparatory images and optionally being further based on first operator input identifying selected tissues within said three-dimensional model; and (c) a simulator for simulating a cryosurgical intervention, which simulator comprises: (i) an interface useable by an operator for inputting second operator input specifying operator-specified loci for insertion of simulated cryoprobes into a space defined by said three-dimensional model, said interface being further useable by said operator for specifying operator-specified operational parameters for operation of said simulated cryoprobes for cryoablating tissues; and (ii) a displayer for displaying in a common virtual space an integrated image comprising a display of said three-dimensional model of said intervention site and a virtual display of said simulated cryoprobes inserted at said operator-specified loci.
