ABERRATION CORRECTIONS FOR DYNAMICALLY CHANGING MEDIA DURING ULTRASOUND THERAPY

원문 (중국어)

Various approaches to delivering ultrasound energy to a target region include, prior to delivery of the ultrasound energy, populating a data structure relating multiple real-time parameter values to corresponding correction values for one or more ultrasound parameter values associated with one or more transducer elements for generating a focal zone of acoustic energy in at least the first portion of the target region; and during the treatment, (i) predicting or causing measurement of at least one of the real-time parameter values in the second portion of the target region or the non-target region; (ii) based at least in part on the predicted or measured real-time parameter value(s) and contents of the data structure, determine the correction value(s) for the ultrasound parameter value(s); and (iii) activate the transducer element(s) based at least in part on the determined correction value(s) for the ultrasound parameter value(s) so as to generate the focal zone in the second portion of the target region.
