Abstract
An ultrasonic diagnostic apparatus is capable of displaying a three-dimensional image by performing three-dimensional scanning in an object with ultrasonic beams at rapid speed. Small transducer blocks are formed through selective connection on a two-dimensional transducer array of an ultrasonic probe. Driving pulse signals are modulated and these driving pulse signals, each having respectively different frequencies, are simultaneously provided to the selected small transducer blocks, causing said small transducer blocks to transmit ultrasonic beams to the interior of the object. Waves reflected from the interior of the object are received by each small transducer block. After the echo signals received by each small transducer block are demodulated, these signals are input to a phasing circuit to generate a plurality of received beam signals. The selected position of the small transducer blocks is moved at each repetition of ultrasonic transmission/repetition. The received beam signals are then image-processed image data, and thus displayed on a display.
