摘要： 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.

摘要： A method and apparatus is disclosed for determining the success of a proposed HIFU Treatment, of an ongoing HIFU Treatment, and/or of a completed HIFU Treatment. An energy density of a given HIFU Treatment may be used as a comparison factor between the given HIFU Treatment and other HIFU Treatments and as a predictor of the success of the given HIFU Treatment. One exemplary energy density is the amount of energy deposited in the treatment region divided by the volume of the treatment region. Another exemplary energy density is the amount of energy deposited in the treatment region divided by the pre-treatment mass of the treatment region. A method and apparatus is disclosed to detect the presence of focal hyperechoic features and non-focal hyperechoic features. A method and apparatus is disclosed to detect the presence of an acoustic obstruction.
