Abstract: The present invention relates to the technical field of medical devices. Disclosed is an adjustable collimator, which can solve the problem that existing collimators cannot achieve precise therapy in a small irradiation field. The adjustable collimator comprises a controller and two blade sets arranged opposite to each other; the blade sets comprise a plurality of blades, the controller drives the blades to move so as to form a first irradiation field through which a ray can pass; at least one blade in the blade set is a small irradiation field blade, and at least one irradiation field hole is provided on the small irradiation field blade; the controller is further used to drive the small irradiation field blade to move such that the irradiation field hole becomes a second irradiation field through which the ray can pass, wherein the second irradiation field is smaller than the first irradiation field.

Abstract: A radiation therapeutic head, a collimator assembly, and a control method of a radiotherapeutic equipment are provided. The therapeutic head includes: a source carrier; first radiation sources for focusing therapy and a second radiation source for conformal therapy that are disposed on the source carrier; a switch body located on an emitting side of the first and second radiation sources and provided with through holes therein, the switch body being configured to control alignment of the through holes with the first and second radiation sources to allow the emission of rays from the first and second radiation sources; and a collimator assembly, the collimator assembly further includes a carrier; a focusing collimator and a multi-leaf collimator disposed on the source carrier.

Abstract: A radiotherapy apparatus incorporating multi-source focusing therapy and conformal and intensity-modulated therapy is disclosed. The radiotherapy apparatus includes a base, a movable couch, a gantry, at least one therapeutic head, and a counterweight. The therapeutic head includes a shielding part, a source carrier received in the shielding part, provided with a focusing radioactive source for focused therapy and a conformal radioactive source for conformal and intensity-modulated radiotherapy, a switch part configured for controlling on/off the source, a shielding door configured for controllably shielding the radiation beams of the radioactive sources; and a collimator assembly. By using this apparatus, accurate multi-source focused therapy and conformal therapy can be implemented in a single current Gamma Knife device.
