Abstract
For an ultrasonic wave to be transmitted, an ultrasonic probe driving unit can apply a stepwise varying drive voltage to the ultrasonic probe. The drive voltage of the driving unit is so selectively set by a setting unit as to allow the output level of the ultrasonic wave to be in a range below, but nearest to, an upper limit. It is, therefore, possible to obtain maximal image quality in a range in which safety is secured.
