Abstract
A system and method are presented for treating targeted tissue using cryoablation. A linear endobronchial ultrasound (EBUS) device is positioned adjacent the targeted tissue and is used to guide a percutaneously inserted cryoprobe into the targeted tissue. The EBUS device is partially rotated in order to create multiple image slices that are combined together. To overcome the acoustic shadow created by the ice ball, a 3D model is created of the ice ball based on the locations identified on visible portion of the ice ball's peripheral surface. These locations are mirrored across an axis defined for the cryoprobe to define an approximate location for the hidden, non-visible periphery. This model is then displayed along with the location of the targeted tissue and an indication of the killing zone of the ice ball defined by a selected isotherm.
