Methods and systems for coupling and focusing acoustic energy using a coupler member
First Claim
1. A system for coupling acoustic energy to a region of interest comprising:
- a crystallized gel comprising water in an amount of from about 10% to about 90% mass, and polyvinyl alcohol in an amount of from about 2% to about 30% mass;
a lens shaped into the crystallized gel;
an ultrasound transducer integrated into the crystallized gel and positioned to emit ultrasound energy through the lens, wherein the crystallized gel is configured to at least one of raise and lower an attenuation of the ultrasound energy;
at least one acoustic impedance matching layer positioned in a path of the ultrasound energy;
an enclosure coupled to the crystallized gel;
at least one of a power supply within the enclosure, the power supply coupled to the ultrasound transducer and configured to provide power to the ultrasound transducer to emit the ultrasound energy;
a controller within the enclosure, and configured to control power and frequency of the ultrasound energy;
a sensor in communication with the controller and configured to communicate a condition of the ultrasound energy; and
an indicator displaying the condition of the ultrasound energy.

Abstract
An exemplary system for coupling acoustic energy using an encapsulated coupler member comprises a display or indicator, a control system, a probe, and a coupler member. This invention provides a coupler member adjustably configured to perform at least one of (i) providing a standoff, (ii) focusing or defocusing energy, and (iii) coupling energy. An exemplary gel coupler member is configured to hold the shape of a lens geometry. In one aspect of the present invention, gel coupler member comprises water, glycerol, and polyvinyl alcohol, and exhibits an increased desiccation time and shelf life when compared to the prior art. The probe can comprise various probe and/or transducer configurations. In an exemplary embodiment, the probe delivers focused, unfocused, and/or defocused ultrasound energy to the region of interest. Imaging and/or monitoring may alternatively be coupled and/or co-housed with an ultrasound system contemplated by the present invention.
