HIGH INTENSITY FOCUSED ULTRASOUND ENHANCED BY CAVITATION

摘要

A medical apparatus (600, 700, 800, 900) comprising a high intensity focused ultrasound system (602) configured for generating focused ultrasonic energy (612) for sonicating within a target volume (620) of a subject (601). The high intensity focused ultrasound comprises an ultrasonic transducer (606) with a controllable focus (618). The apparatus further comprises a memory (634) containing machine executable for controlling the medical apparatus and a processor (628) for executing the instructions. Execution of the instructions causes the processor to cause (100, 200, 300, 400, 502) ultrasonic cavitations at multiple cavitation locations (622, 1002) within the target volume using the high intensity focused ultrasound system. Execution of the instructions further cause the processor to sonicate (102, 206, 306, 402, 504) multiple sonication locations (1004) within the target volume using the high intensity focused ultrasound system. The multiple sonication locations and the multiple cavitation locations are targeted by adjusting the controllable focus.
