Abstract

The invention discloses source loading equipment which comprises a filing room set up by block-shaped shielding materials and a lead filing room. The filling room is located above the lead filling room and communicated with the lead filling room. A room wall of one side of the filling room is provided with a butt joint interface abutting against radioactive source using equipment. A lifting device used for lifting a hanging basket in a lead tank is arranged in the lead filling room in a penetrating mode, and comprises a driving device arranged on the outer side of the lead filling room. A manipulator is arranged in a room wall of the opposite side of the butt joint interface of the filling room in a penetrating mode and comprises a pickup end and an operating end, the pickup end is arranged in the filling room, the operating end is located outside the filling room, and the filling room is further provided with an observation device observing the installation process of a radioactive source. The invention further discloses a radioactive source inverted installation method. Through the adoption of the block-shaped shielding materials, appropriate inverted installation equipment can be set up according to the specific installation size of the using equipment, generalization is achieved, using flexibility is increased, cost can be reduced for manufacturers owing various different radioactive source using devices, and efficiency is improved.

Description

technical field [0001] The present application relates to a radiation source transmission device, in particular to a source loading device and a radiation source inversion method for a radiotherapy device. Background technique [0002] Radiation therapy equipment is a medical device that uses radiation to treat human diseases. There are many ways for the equipment to generate radiation, including physical processes (such as bremsstrahlung to generate X-rays) and radioactive nuclides to decay by themselves (such as cobalt 60 to decay to generate gamma rays). For radiotherapy equipment using radionuclides, during the installation process, after the mechanical and electrical commissioning is completed, the loading of radioactive sources and a series of dosimetric index tests must be carried out. After the equipment is used for a certain period of time, the radioactive source becomes weak due to decay and needs to be replaced or refilled. Taking the radioactive source cobalt-60...
