Abstract:
A system for performing a therapeutic procedure in a target region of a patient using focused ultrasound, comprising:a transducer array comprising a plurality of sub-arrays, each sub-array defining an acoustic emission surface and including one or more transducer elements configured for emitting acoustic energy from the acoustic emission surface, each sub-array being independently movable with respect to one another about at least two respective axes of rotation; drive circuitry coupled to the transducer elements, the drive circuitry configured for providing respective drive signals to the transducer elements, whereby the transducer elements may emit acoustic energy from their respective acoustic emission surfaces; and a mechanical controller coupled to the sub-arrays and configured for moving the sub-arrays about the at least two respective axes of rotation to adjust an orientation of the acoustic emission surfaces of respective sub-arrays to facilitate focusing of the acoustic energy emitted by the transducer elements towards the target region.
