[0002] In the focused ultrasound treatment of the prior art, B-ultrasound equipment is mostly used for positioning and monitoring treatment. There are following disadvantages in using this B-ultrasound equipment for monitoring and treatment: 1. Since the B-ultrasound image is only a plane image at a certain angle, even if the B-ultrasound image is used The three-dimensional ultrasound system still has certain limitations in its viewing area; 2. The observable depth of ultrasound images is limited, and the impact of bony substances on the images is particularly large, and the tissue behind the bone can hardly be observed, and there are artifacts; 3. Ultrasound The image has poor ability to identify tissue boundaries, especially for small tumors and deep tumors.

[0007] The above-mentioned patents are all combined treatment systems using MRI devices and ultrasonic treatment equipment. These treatment systems mainly have the following disadvantages: 1) Since the movable height under the MRI bed is very limited, ultrasonic transducers are arranged under it for multiple coordinates. It is very difficult to move, and it is even more difficult to arrange a complex motion positioning mechanism. After the motion positioning mechanism is arranged under the bed of the MRI hole, it occupies the limited movement space of the ultrasonic transducer, thus affecting the treatment. 2) The motion positioning mechanism arranged in the aperture of the MRI device will interfere with the MRI device, thus making the obtained tissue image inaccurate, so it is necessary to perform high-demand non-magnetization on the ultrasonic transducer and its motion positioning device Design and processing increase the technical complexity and manufacturing cost; 3) Driven by the motion positioning mechanism, the ultrasonic transducer can only perform limited movements, and cannot adapt to the multi-directional requirements of the treatment of tumors and other diseases
