Abstract

The present application provides a multi-leaf collimator, a double-layer multi-leaf collimator, and a medical device. The first direction is a direction perpendicular to the central axis of the beam emitted by the radiation source. A plurality of first vanes reciprocate along the first direction on the first vane mounting structure, and a plurality of second vanes reciprocate along the first direction on the second vane mounting structure. The first direction and the second direction intersect, and the first blade mounting structure and the second blade mounting structure reciprocate along the second direction on the two opposite first sliding mounting structures, and always swing around the radioactive source, forming a radioactive source. Arc with the center of the circle. A plurality of first blades and a plurality of second blades move in the first direction or / and the second direction to block the rays emitted by the radiation source, and the shape of the field can be dynamically adjusted, not limited to a specific position, and then Achieves resolution at different locations throughout the field.

Description

technical field [0001] The present application relates to the technical field of medical equipment, and in particular, to a multi-leaf collimator, a double-layer multi-leaf collimator and medical equipment. Background technique [0002] The medical equipment often used in tumor treatment is radiotherapy equipment, which uses the radiation emitted by the radiotherapy equipment to kill tumor cells. Radiation therapy equipment typically includes a multi-leaf collimator (MLC) for conformal adjustment of the radiation emitted by the radiation source. The multi-leaf collimator is a mechanical moving part used to generate a conformal radiation field, which is used for conformal adjustment of the radiation emitted by the radiation source. The multi-leaf collimator includes a blade, a blade guide box and a driving device. The driving device directly drives the blade to reciprocate along the inner wall of the box in the blade guide box, and adjusts the position of the blade, so that...
