Abstract
A system to apply ultrasound energy to a region surrounding blood flow in a blood vessel from a position outside a patient includes: a therapeutic ultrasound transducer comprising a plurality of transducer elements; and a processor configured to control the plurality of transducer elements; wherein the processor is configured to change phase inputs to the transducer elements to move a focus of the transducer at least 1 cm in a first plane which is substantially along a plane of the transducer elements of the therapeutic ultrasound transducer and at least 1 cm in a second plane orthogonal to the first plane; and wherein the processor is further configured to position the focus of the transducer in sequential positions offset from the blood flow in the blood vessel according to a pattern pre-determined by an operator of the system.
