Title:
ULTRASONIC DIAGNOSTIC EQUIPMENT
Document Type and Number:
Japanese Patent JP3302936
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To reduce the number of transmission drivers without damaging a form of an input beam.
SOLUTION: Inserting switches (diodes) 51-66 between transmission drivers 31, 33, 35, 37 enables one driver to drive a plurality of oscillators and to process independently each oscillator's signal at the time of receiving it. As a result, it is possible to obtain images with less degradation in image quality by use of a few drivers.
