Abstract
Methods and apparatuses are disclosed to optimize an acoustic transducer, such as an ultrasound transducer, for use in a therapy application, such as high intensity focused ultrasound. In one example, the thickness of a matching layer applied to a face of a transducer member is altered to optimize the transducer for high intensity focused ultrasound operation at a desired frequency based on total power measurements as a function of acoustic frequency and lapping iterations.
