摘要
The present invention relates to systems and methods for rendering visible to a cryosurgeon an estimated border of a cryoablation volume, thereby facilitating accurately delimited cryoablation of pathological tissues. More particularly, the present invention relates to systems and methods for reading temperature and location information from images provided by imaging modalities and optionally from thermal sensors, inferring from that information the three-dimensional shape and position of a volume of tissue considered reliably cryoablated, and presenting this shape and position information to a cryosurgeon by integrating a visual model of that information with one or more images derived from standard imaging modalities, and displaying for a cryosurgeon that integrated image. Preferred embodiments include systems and methods for MRI-guided cryosurgery and for automatic control of elements of cryoablation procedures.
