Abstract
Official abstract text for this publication.
An ultrasound treatment includes applying ultrasound at a first energy level to a region of interest in a subject for activating a cavitation nucleation agent during a first portion of a treatment cycle. Ultrasound at a second energy level is applied to the region of interest during a second portion of the treatment cycle for implementing a desired thermal therapy in the presence of the cavitation nucleation agent activated during the first portion of the treatment cycle. The second energy level is at an energy level different from the first energy level.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of ultrasound treatment comprising the acts of: applying first ultrasound at a first energy level to a shielding location outside a region of interest in a subject for activating a cavitation nucleation agent at the shielding location during a first portion of a treatment cycle, wherein the activated cavitation nucleation agent creates a shielding layer at the shielding location to shield structures outside the region of interest; after the…
