Abstract: A device and method for controlling the rotation of radiotherapy equipment are provided. The device includes: a detector, configured to detect the rotation of a rotational load of the radiotherapy equipment, and record a rotational deviation amount when the rotational load rotationally deviates; and a controller, configured to generate correction instructions for eliminating the deviation according to the rotational deviation amount when the detector detects the rotational load of the radiotherapy equipment rotationally deviates. The deviation occurred to the rotation of the rotational load is timely corrected by monitoring the actual rotation of the rotational load of the radiotherapy equipment, thereby improving the safety and positioning accuracy of the radiotherapy equipment.

Abstract: A positioning stud for radioactive therapy includes a stud rod, a stud tip, and an insulating component. The insulating component is connected between the stud rod and the stud tip, and is used to prevent contact between the stud rod and the stud tip.

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: The present disclosure discloses a device for controlling rotation of a radiotherapy equipment, for controlling rotation of at least one rotational load of the radiotherapy equipment about a rotation axis. The device and the radiotherapy equipment form a full-closed-loop structure.

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.

Abstract: A medical cabin system comprises a safety protection structure, an identification structure, an environment simulation structure, a radiotherapy isolation structure, and one or more other independent walls. The safety protection structure is disposed on an entrance of the medical cabin system. The identification structure is disposed on a medical equipment of the medical cabin system or in an enclosed space defined by a stereo location region of the medical cabin system. The environment simulation structure is disposed on a top portion and at least one side wall of the medical cabin system. The radiotherapy isolation structure isolates the stereo location region from a radiotherapy region of the medical cabin system. The independent walls define at least one enclosed space with the radiotherapy isolation structure.
