A derating method for therapeutic applications of high intensity focused ultrasound

Nonlinear derating of high-intensity focused ultrasound beams using Gaussian modal sums.

A method is introduced for using measurements made in water of the nonlinear acoustic pressure field produced by a high-intensity focused ultrasound transducer to compute the acoustic pressure and temperature rise in a tissue medium. The acoustic pressure harmonics generated by nonlinear propagation are represented as a sum of modes having a Gaussian functional dependence in the radial directio...

High-Intensity Focused Ultrasound –

High intensity focused ultrasound (HIFU).

INTRODUCTION Curative treatments for localized prostate cancer, from least invasive to most invasive, include brachytherapy, cryosurgery, three-dimensional conformal radiation therapy, external beam radiation therapy, and radical prostatectomy. A patient with localized, low risk or intermediate risk prostate cancer who is diagnosed at an early age and receives one of these treatments has only a...
