Abstract
In an ultrasonic imaging apparatus, when a sampling time space determined corresponding to the respective phases of receiving signals from transducer elements adjacent to each other is shorter than the settling time of sample and hold circuits, these receiving signals are sampled at the same time. Noise is prevented from being mixed with the sample and hold values of these signals.
