Real time autofocusing hardware for ultrasonic imaging with interfaces

A hardware architecture for fast imaging (multi-beamforming) with auto-focusing capabilities is presented. Auto-focusing is carried out without the knowledge of probe-part geometry, which is obtained by ultrasound measurements. The proposed technique and hardware achieves a high throughput that allows autofocus in real-time (for instance, in part scanning applications). The paper yields some figures of performance and other preliminary results.
