Methods and systems for generating thermal bubbles for improved ultrasound imaging and therapy
First Claim
1. A method of providing ultrasound treatment of a medium, the method comprising:
- a) coupling an acoustic source to a region of interest, the region of interest located at a surface of the medium or below the surface of the medium;
b) delivering a first acoustic energy from the acoustic source into the region of interest, the first acoustic energy configured to create thermal bubbles in the region of interest and form a boundary comprising the thermal bubbles, the boundary defining an inner portion of the region of interest surrounded by the boundary and an outer portion of the region of interest surrounding the inner portion and the boundary; and
c) delivering a second acoustic energy from the acoustic source into the inner portion of the region of interest, the outer portion of the region of interest, or the boundary.

Abstract
A method and system uniquely capable of generating thermal bubbles for improved ultrasound imaging and therapy. Several embodiments of the method and system contemplates the use of unfocused, focused, or defocused acoustic energy at variable spatial and/or temporal energy settings, in the range of about 1 kHz-100 MHz, and at variable tissue depths. The unique ability to customize acoustic energy output and target a particular region of interest makes possible highly accurate and precise thermal bubble formation. In an embodiment, the energy is acoustic energy. In other embodiments, the energy is photon based energy (e.g., IPL, LED, laser, white light, etc.), or other forms, such radio frequency electric currents (including monopolar and bipolar radio-frequency current). In an embodiment, the energy is various combinations of acoustic energy, electromagnetic energy and other energy forms or energy absorbers such as cooling.
