ULTRASONIC IMAGING DEVICE

摘要

An ultrasonic imaging device having refraction correction delay data creating means for creating a delay time for focusing the transmitted or received wave in consideration of the effect of refraction of ultrasonic wave by an ultrasonic propagation medium between arrayed vibrators and the preset focal point and supplying the delay time to delay control means so as to create an excellent ultrasonic image while preventing any focal shift of the ultrasonic wave transmission/reception due to refraction of the ultrasonic wave caused at the interface between a lens layer of an ultrasonic probe and the fat layer of the subject and at the interface between the fat layer and the biological tissue present under the fat layer.
