Abstract
In an ultrasonic imaging apparatus utilizing an array type ultrasonic probe having a number of arrayed probe elements, high frequency pulse signals subject to different delays are supplied to respective probe elements so as to generate an acoustic beam which converges to a predetermined focal point. When receiving a reflection acoustic beam resulting from the converging beam, a plurality of signal lines extending from respective probe elements are connected in common to set up a plurality of element groups each having a plurality of adjacently arrayed elements and respective signals derived from respective element groups are differently delayed and added together to generate a reception signal representative of a reception beam having a predetermined focal point.
