Abstract
In an ultrasonic inspection and imaging instrument, a pulse generator and a burst wave generator are provided in association with the activation of an ultrasonic probe by the pulse generator and in response to a measurement value obtained from a signal reception circuit portion. A first gate position is obtained with regard to an inspection portion in a sample, and then a second gate position for a burst wave measurement is set by correcting the first gate position. The burst wave measurement is performed by activating the burst wave generator.
