Abstract

The invention provides a multi-leaf collimator and relates to the technical field of medical appliances, and the multi-leaf collimator can be used for solving the problem caused by complicated structure of a secondary feedback device of an existing blade. The multi-leaf collimator comprises at least one blade and at least one stay cord sensor, wherein the stay cord sensor comprises a flexible part which can be extended and contracted; and the flexible part comprises a free end; the free end of the flexible part is connected with the blade.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a multi-leaf collimator. Background technique [0002] The purpose of external beam radiation therapy is to form an effective dose in the tumor target area while reducing the adjacent normal tissue dose. Early on, the beam was modulated with a small number of basic shapes such as a circle or a square, but for most irregularly shaped tumors, this approach resulted in excess radiation to normal tissue. Conformal Radiotherapy (CRT, Conformal Radiotherapy) can adapt the dose distribution to the shape of the tumor, so as to ensure that sufficient doses are transmitted to the lesion area while minimizing normal tissue reduction. [0003] A key component for realizing conformal radiotherapy technology is a multi-leaf collimator (MLC, Multi-leaf Collimator). example, such as figure 1 As shown, the multi-leaf collimator includes multiple pairs of leaves 1, guide rail frame ...
