ULTRASONIC SYSTEM FOR PICKING-UP IMAGE OF SCATTERED OBJECTS IN MEDIUM AND ULTRASONIC DIAGNOSTIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an improved ultrasonic diagnostic system. SOLUTION: The system is provided with a probe 203 for transmitting ultrasonic wave and detecting ultrasonic echoes reflected from ultrasonic scattered objects. The probe is provided with a first group of conversion elements labeled with a transmission group T so as to transmit ultrasonic wave and the other second group of conversion elements labeled with a reception group R so as to detect the ultrasonic echoes which are reflected against the ultrasonic scattered objects. The system is also provided with respective transmission and reception means which are connected to the probe to supply encoding signals to the transmission group T and to receive signals from the reception group R, with a processing system which comprises a transmission beam generating means for focusing ultrasonic wave on a focus line, a reception beam generating means for generating a reception signal being the sum of beams from the signal received from the focus line and a processing means for processing the reception signal being the sum of the beams in order to generate a decoding signal and with a means for displaying an image being the function of the decoding signal.
