Abstract
An ultrasonic diagnosing apparatus for acquiring Doppler information at a focal point in an object under inspection from AC components of a spatial frequency distribution of ultrasonic waves reflected from the focal point by removing components reflected from an off-axial static reflector. A transmission trigger generating circuit drives in accordance with predetermined time shifts an array of piezo-electric elements to transmit an electronically converged ultrasonic beam. Reflected signals from a reflector on the axis of the beam only are stored in memory.
