High-intensity ultrasound therapy system guided by movable ultrasonic therapy equipment and diagnostic imaging equipment

The invention belongs to the technical field of ultrasonic therapy, and relates to a high-intensity ultrasonic therapy system guided by a movable ultrasonic therapy device and a diagnostic imaging device. Background technique

High-intensity focused ultrasound therapy can generate high-intensity, continuous ultrasound energy on the lesion by focusing the ultrasound, resulting in transient high-temperature effects (60 °C ~ 100 °C), cavitation effects, mechanical effects and sonication effects. The cell membrane, the nuclear membrane is ruptured, the protein is coagulated, and the lesion tissue is selectively coagulative necrosis, so that the lesion loses the ability to proliferate, infiltrate and metastasize. High-intensity focused ultrasound therapy has been clinically recognized as a new technology for the treatment of tumors and other diseases, and is widely used clinically in the treatment of a variety of tumors and non-neoplastic diseases.

The prior art is used for ultrasonic treatment equipment, such as the "ultrasound focused tumor ablation machine" produced by Shanghai Aishen Technology Development Co., Ltd., etc., when the treatment is performed, the patient is placed on a fixed treatment bed, and the patient is placed above the patient. The ultrasound treatment device treats the lesion.
