Abstract
Various approaches for delivering ultrasound energy to a target region during a therapeutic or diagnostic procedure includes implementing an adjustment mechanism having a machine-learning model that has been trained, based on input vectors corresponding to a difference and/or a ratio of parameter values between multiple transducer elements, to generate, for each of the transducer elements, one or more parameter value to compensate for expected beam aberration resulting for an intervening tissue; and activating the transducer elements in accordance with the corresponding parameter values so as to generate an optimized focal zone at the target region during the therapeutic or diagnostic procedure.
Claims34
A system for delivering ultrasound energy to a target region during a therapeutic or diagnostic procedure, the system comprising:
- an ultrasound transducer comprising a plurality of transducer elements, at least some of the transducer elements being designated as active during the therapeutic or diagnostic procedure;
- an adjustment mechanism comprising a machine-learning model that has been trained on input vectors;
- wherein the input vectors are constructed from at least one of a difference or a ratio of parameter values between a plurality of the transducer elements, the adjustment mechanism being configured (i) to receive numeric quantities characterizing tissue intervening between the active transducer elements and the target region and (ii) to generate, based on the input vectors and for each of the active transducer elements, at least one parameter value to compensate for expected beam aberration;
- and
- a controller configured to activate the active transducer elements in accordance with the corresponding parameter values so as to generate an optimized focal zone at the target region during the therapeutic or diagnostic procedure.
