ULTRASONIC DIAGNOSIS APPARATUS, ULTRASONIC DIAGNOSIS SYSTEM AND ULTRASONIC DIAGNOSIS PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an ultrasonic diagnosis apparatus which can continuously provide a highly precise ultrasonic image, even if it has worked for a long time to deteriorate the function of an organic piezoelectric element; an ultrasonic diagnosis system therefor; and an ultrasonic diagnosis program therefor. SOLUTION: The ultrasonic diagnosis apparatus utilizes the relationship in correspondence between the working record and the deterioration in function of an organic piezoelectric element to change an amplification rate, at which a received electric signal converted by the organic piezoelectric element is amplified by an amplifier in accordance with the working record.
