At present, medical personnel can adopt one hand to hold the transducer when carrying out ultrasonic imaging diagnosis to the patient, then places and scan the formation of image at the position that needs the inspection, controls on the supersound host computer on the other hand, and is very inconvenient. For example, the user cannot quickly and accurately find the section of the part to be detected due to experience reasons or other objective reasons; or holding the transducer for extended periods of time is prone to user fatigue.

There are also devices that fix an ultrasound transducer on a supporting arm and then manually move the ultrasound transducer to an examination site for examination, for example, in a cardiac examination, a medical staff member moves a transducer module to a heart of a patient for scanning through the supporting arm, but this still allows the operator to adjust the position and posture of the transducer to obtain a target detection section. Or some equipment is automatically adjusted by using an industrial mechanical arm, but the mechanical arm controlled by six degrees of freedom is high in price and high in cost.

Therefore, how to automatically control the position and posture of the transducer to perform scanning imaging after the medical staff selects the part to be examined becomes a technical problem to be solved by those skilled in the art.

And repeating the steps until all standard sections are checked. The position and the posture of the transducer are required to be adjusted for multiple times to obtain a target detection section of the detection part, and the working efficiency is low.
