ULTRASONIC RECEIVER AND RECEIVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a means of forming beams and processing signals including CW process in a completely digital domain. SOLUTION: An ultrasonic receiver which processes the images including CW Doppler in a digital domain. This ultrasonic receiver is consisting of a converter having a plurality of converting elements and an ultrasonic receiver having a plurality of channels (305) that receive analog echo signals (electric signal) and has a dynamic range of at least 154 dB/sqrt Hz, outputting the digitized analog echo signals using an A/D converter (320) that can convert signals.
