Self-shielding radiotherapy equipment

Technical Field

The utility model belongs to the technical field of medical equipment, concretely relates to self-shielding formula radiotherapy equipment.

Background

Before the gamma knife treatment device is used, the specific position of the head tumor of the patient relative to the wound positioning device needs to be determined through other examination imaging equipment, so that the head of the patient is fixed according to the specific position of the head tumor of the patient on the wound positioning device. The gamma knife treatment is divided into head gamma knife treatment and body gamma knife treatment. The gamma knife therapy for head is carried out by installing multiple cobalt sources in a spherical helmet, focusing the cobalt sources at a certain point in the cranium, and forming a narrow-beam gamma ray with sharp edge. When in treatment, narrow beams of rays are converged on the focus to form a limited high-dose area to destroy the focus, and the method is mainly used for treating intracranial small tumors and functional diseases. The body part gamma knife therapy is mainly used for treating various tumors of the whole body.
