Abstract:
1. An ultrasound system comprising a transducer, a controller arranged to generate control signals arranged to control the transducer to generate pressure waves directed at a target volume thereby to generate cavitation at a position in the target volume, and at least one sensor arranged to sense the cavitation and to output sensing signals, wherein the controller is arranged to: define a parameter of the sensing signals which is dependent on the position of the cavitation; define a target range of the parameter corresponding to a target range of the position; receive the sensing signals from the at least one sensor; measure a value of the parameter for the received sensing signals; determine whether the value is outside the target range and to change the control signals in response to the parameter being outside the target range thereby to maintain the position of the cavitation within the target range.
