Abstract
An ultrasound system comprises a transducer, a controller arranged to generate control signals arranged to control the transducer to generate pressure waves directed at a target volume, and sensing means arranged to sense cavitation in the target volume. The controller is arranged to receive sensing signals from the sensing means and to vary the control signals in response to the sensing signals thereby to control the cavitation.
Claims18
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, and at least one sensor arranged to sense cavitation in the target volume and output sensing signals, wherein the controller is arranged to receive the sensing signals from the at least one sensor and to vary the control signals in response to the sensing signals thereby to control the cavitation.
A method of controlling cavitation in a subject comprising generating pressure waves directed at a target volume to cause cavitation in the target volume, sensing changes in the cavitation in the target volume, and controlling the pressure waves in response to the changes thereby to control the cavitation.
A method of setting up a pressure wave control system comprising producing a control signal to control a pressure wave transmitter so as to produce cavitation in a subject, sensing the cavitation using at least one sensor arranged to output a sensing signal indicative of a parameter of the cavitation, varying the control signal so as to vary the cavitation, defining a sensing parameter of the sensing signal, measuring a controlled parameter of the cavitation which is to be controlled by the system, determining how the sensing parameter varies with variations in the controlled parameter, and selecting a target value of the sensing parameter corresponding to a target value of the controlled parameter.
