Collimator using for radiosurgery and collimator adapter for collimator and installation holder for collimator adapter

摘要

The present invention relates to a collimator for collimation, collim adapter and collim adapter mounting holder. It is mounted on the mounting holder located on the head of the rotating gantry of the linear accelerator for radiation therapy, and supports collimator to pass the radiation generated from the radiation emitting part in the head to project the irradiation area of a certain diameter to the affected part. A sliding plate detachable from the mounting holder and mounted to the mounting holder and spaced apart from the radiation emitting unit by a predetermined distance, and having a through hole through which the radiation passes; A cylindrical holder body extending vertically with respect to the sliding plate with the through-hole included in the inner region and having a supporting groove formed in the circumferential direction on the outer circumferential surface thereof to support the collimator therein; It is characterized in that it comprises a mount holder having a detachable means for fixing relative to the holder body and the collimator fixed to the holder body in the state supported by the groove and the collimator fixed to the holder body from the holder body; .;The present invention made as described above, since the mounting and detachment of the collimator to the collimator adapter is almost instantaneous, there is no waste of time required to replace the collimator during the procedure, so that the procedure can be performed intensively, especially the collie The meter adapter itself also has the effect of being easily removable to the head of the rotating gantry.
