Ultrasonic diagnostic apparatus capable of functional addition

摘要

An ultrasonic diagnostic apparatus (101) of a mechanical scanning system has: a receiving/transmitting unit (104) for receiving and transmitting an ultrasonic wave from/to an ultrasonic vibrator (102); and a PC (110). The PC (110) has: a PC board (108) mounted detachably, which controls a motor driving circuit (105) via the receiving/transmitting unit (104), rotates the ultrasonic vibrator (102) that is mounted to the rotary shaft of a motor (106) to become the center of the rotation by rotating the motor (106) in response to a motor drive signal, controls the receiving/transmitting unit (104), and performs a predetermined digital signal process for an ultrasonic echo signal from the receiving/transmitting unit (104); a PC internal memory (109a) for storing a digital signal from the PC board (108); a general CPU (109); and the like.
