Abstract
Abstract In a ultrasonic wave diagnosis apparatus wherein a probe for transmitting and receiving ultrasonic wave to and from a portion of a patient to be diagnosed is scanned in a sector shape, the probe is driven at a uniform speed by a galvanometer energized by the output of a triangular wave generator. The probe is immersed in electric insulating acoustic medium having a relatively large viscosity and high transmission loss.
