HIGH INTENSITY FOCUSED ULTRASOUND PATH DETERMINATION
First Claim
11. A system for high intensity ultrasound path determination, the system comprising:
- at least one therapy transducer operable to transmit high intensity focused ultrasound;
at least one imaging transducer operable to transmit acoustic energy for imaging; and
a processor operable to determine an origin of a beam of the high intensity focused ultrasound relative to a treatment region, the origin determined as a function of patient characteristics between origin options and the treatment region, and the processor being operable to determine the patient characteristics and origin as a function of data received with the imaging transducers.

Abstract
Paths are determined for high intensity focused ultrasound. A subset of possible paths is selected for the application of high intensity focused ultrasound. Obstructions (e.g., bone or metal), tissue characteristics (e.g., organ or tissue sensitivity to heat or attenuation characteristic), distance, or another factor are used to select the scan lines for high intensity focused ultrasound. The selection may be aided by ultrasound imaging data, such as data representing a volume. The response from different regions is used to identify the tissue characteristics or obstructions. The factors may also be used to determine a dose (power) and/or frequency of the high intensity focused ultrasound.
