Abstract

Over the last few years, improvements in electronic focusing techniques and electronic steering of the acoustic beam have resulted in the very rapid development of apparatus using arrays of piezo-electric transducers. Such instruments, whether they use linear or sectorial electronic scanning, make real-time exploration of organs possible, supplying images with excellent resolution. One can therefore by using linear scanning with 5 MHz frequency probes, visualize surface vessels with a lateral resolution at 6 dB better than 1 mm.
