ULTRASONIC DIAGNOSTIC EQUIPMENT

摘要

PROBLEM TO BE SOLVED: To provide ultrasonic diagnostic equipment which can increase the level of amplitude of a higher harmonic component which can be accumulated in reflected ultrasonic signals.

SOLUTION: The ultrasonic diagnostic equipment includes: a transmission means provided with a piezoelectric part to transmit ultrasonic signals to a subject; a reception means provided with a piezoelectric part to receive reflected ultrasonic signals generated by reflection of ultrasonic signals in the subject to covert the ultrasonic signals to electric signals; an image processing part to generate the ultrasonic image inside the subject from the electric signals; and a higher harmonic extracting part for extracting higher harmonic components included in the reflected ultrasonic signals. The ultrasonic signals include a basic wave and an n-order higher harmonic component having a phase to offset the n-order harmonic wave included in the reflected ultrasonic signals.
