Abstract
Abstract A booster for treatment of a disease, comprising: an ultrasound source producing ultrasound energy to a fluid that delivers the ultrasound energy to a selected body site; and a sufficient number of microbubbles with a size of 0.1 to 100 µm to reduce a cavitation energy threshold of at least a portion of the fluid and provide a cavitation therapeutic effect.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
61 words
A booster for treatment of a disease, comprising: an ultrasound source producing ultrasound energy to a fluid that delivers the ultrasound
energy to a selected body site; and a sufficient number of microbubbles with a size of 0.1 to 100 µm to reduce a cavitation
energy threshold of at least a portion of the fluid and provide a cavitation therapeutic effect.
Claim 2
Dependent Claim
18 words
