Abstract
An ultrasonic diagnostic apparatus has a probe having a plurality of channels, a receiving circuit for dividing receiving signals from the probe to deliver them in the form of "K" (K being an integer which is 2 or more) blocks each having a predetermined number of channels, a selector circuit for selecting signals corresponding to respective ones of the blocks from output signals of the receiving circuit and delivering the selected signals, a signal distributor for selecting the output signals of the receiving circuit in the mode of single beam reception and selecting the output signals of the selector circuit in the mode of simultaneous parallel beam reception, "K" delay circuits connected to outputs of the signal distributor and each having the predetermined channels, and a switch for switching the "K" delay circuits to series connection in the mode of single beam reception and switching the "K" delay circuits to parallel connection in the mode of simultaneous parallel beam reception.
