Description

technical field [0001] The invention relates to the technical field of ultrasonic imaging equipment, in particular to a four-dimensional ultrasonic probe motor control system. Background technique [0002] In the ultrasound imaging system, the images obtained by ordinary probes are two-dimensional images. If you want to obtain four-dimensional images, you need to use a special ultrasound probe—four-dimensional ultrasound probe. The four-dimensional ultrasonic probe is composed of an ordinary ultrasonic transducer plus a motor and a transmission device. When the motor drives the transmission device to make the ultrasonic transducer oscillate around an axis, during the oscillating process of the ultrasonic transducer, the transmitting module applies a transmitting voltage to the ultrasonic transducer to make it emit ultrasonic waves, and when the ultrasonic waves propagate in the human body, Reflections will be generated on uneven surfaces between tissues in the body, and the...
