An ultrasonic volumetric scanner for image-guided surgery

Abstract The design of a two-dimensional ultrasonic array for providing real-time volumetric imaging during minimally invasive surgery is presented. The array is fully populated with capacitive micromachined ultrasonic transducers. A custom-designed experimental system is used to capture A-scans from the transducers. Pulse-echo images from a 16-element 1D array have been constructed. Point spread functions have been simulated for both 1D and 2D arrays.
