2019-116 - Focused Ultrasound Transducer with Electrically Controllable Focal Length

Description:

Market Opportunity

Focused ultrasound (FUS) has a wide application potential in imaging, tumor treatment, neuron stimulation and other areas. Previously designed transducers are of a fixed focal length, with no electrical controllability for focal length, and are incapable of dynamically changing the focal spot without moving the transducer.

USC Solution

USC researchers have designed a new device with a tremendous degree of operating freedom by enabling the electrical controllability of the focal length. By using the new design, a real-time, fast-response, on-demand changing of focal length can be achieved. Electrical controlling of the focal length is achieved by selecting a group of electrodes to actuate so that the acoustic waves generated from those selected electrodes will arrive at the desired focal length in-phase, interfere constructively, and create a high acoustic intensity focal spot.

Value Proposition

  • On-demand focal adjustment with sub-millimeter focal spot precision
  • Electrical tuning of the focal length in real time
  • Accelerate throughput in therapeutic and imaging workflows, lowering setup time and enhancing precision
