Claim Text:
1. A system for facilitating administration of a High Intensity Focused Ultrasound (HIFU) beam relative to a target area, the system comprising; a. a HIFU capable transducer; b. a diagnostic imaging probe; and c. a processor in communication with the HIFU capable transducer and diagnostic imaging probe, wherein the processor, HIFU capable transducer, and diagnostic imaging probe are configured to perform the processes of (i) dynamically determining a desired treatment location of the target area, wherein the step of dynamically determining includes detecting and localizing a site for treatment using 3D Doppler ultrasound based techniques, and (ii) cyclically repeating a tracking and guiding of a HIFU beam therapy before the HIFU beam therapy commences and recommences to create a dynamically self-correcting system, the tracking and guiding being applied to reorient and refocus the HIFU capable transducer, and wherein the diagnostic imaging probe is adapted to obtain a first set of imaging data for the target area, wherein the HIFU capable transducer is adapted to induce a radiation force relative to the target area using low power sonication, wherein the diagnostic imaging probe is further adapted to obtain a second set of imaging data for the target area after the radiation force has been induced, and wherein the processor is adapted to compare the first and second sets of imaging data to determine a focal position for the HIFU capable transducer relative to the target area, the processor further adapted to adjust an orientation and focus of the HIFU capable transducer such that the adjusted orientation and focus of a new focal position of the HIFU capable transducer substantially matches the desired dynamically determined treatment location of the target area.
