Systems and Methods for Simultaneously Treating Multiple Target Sites
First Claim
Patent Images
1. A system for delivering acoustic energy to a plurality of target sites within a patient, the system comprising:
- a transducer array comprising a plurality of transducers each transmitting acoustic energy to a respective focus, the foci being discontiguous and forming a pattern of target sites;
a processor coupled to the array for establishing targeting criteria corresponding to the pattern; and
a controller coupled to the processor and the transducers, the controller driving the transducer elements based at least in part on the targeting criteria.

Abstract
The emission intensities of groupings of transducer elements of an ultrasound transducer array are controlled based on targeting criteria in such a manner as to simultaneously create multiple discontiguous foci, each corresponding to one of a plurality of target sites.

18. A method for simultaneously delivering focused ultrasound to a plurality of discontiguous target sites, the method comprising:
-
providing an ultrasound transducer array comprising a plurality of transducer elements; determining one or more targeting criteria for each element with respect to the target sites; determining element groupings based on the targeting criteria; and driving the transducer elements based upon the respective element groupings to simultaneously focus acoustic energy transmitted by the transducer elements at the plurality of target sites. - View Dependent Claims (19, 20, 21, 22, 23, 24)
