A Low Cost Compact 512 Channel Therapeutic Ultrasound System For Transcutaneous Ultrasound Surgery

A low cost 512 channel therapeutic ultrasound system was designed and tested with a 2D array transducer. The system was optimized for high energy, low duty cycle pulsing applications (cavitation mediated therapy), but is also folly compatible with continuous wave applications. The effective steering range was measured to be 40 mm FWHM over a 3D volume. Well defined volumes of liver tissue were disrupted with high energy cavitation generating ultrasound pulses in ex‐vivo liver experiments.
