Preliminary
results from a pig model suggest that it is feasible to create volumetric
thermal lesions within in-vivo tissue using dynamic movement of the focal
point of a High-Intensity Focused Ultasound beam with real-time multi-slice
monitoring, and feedback control. The
measured thermal dose diameters and lengths correspond closely with planned
dose diameters for treatment cell sizes ranging from 4-16 mm in diameter.
