Abstract
An ultrasonic imaging apparatus comprising an ultrasonic transducer, and a delay circuit section. The transducer has an array of ultrasonic transducer elements, and emits ultrasonic waves and receives echo waves to convert these waves into echo signals. The delay circuit section delays the echo signals by delay times determined by at least the directions in which the ultrasonic waves have been emitted from the transducer. This circuit has first and second memories for alternately writing and reading the echo signals, and a circuit for addressing the first and second memories by applying these memories with addresses, the number of which corresponds to the delay time.
