Problems solved by technology

[0002] The treatment head of the new stereotactic radiotherapy equipment has a rotating drum, and the treatment head with a ray emitting device is installed on the drum to rotate synchronously with the drum. In addition, the drum is also provided with an arc-shaped guide rail for the treatment head to move along the second direction. The treatment head The intersection of the rays moving to different positions is the isocenter of the radiotherapy equipment. During the installation and commissioning stage of the radiotherapy equipment, the treatment head does not emit a beam of radiation, so it is impossible to find the position of the isocenter with the naked eye. It can only be detected by electronic photosensitive or film after the radiotherapy equipment is completely installed. The position of the isocenter is determined by photosensitive method, which will affect the efficiency of installation and commissioning of radiotherapy equipment and increase the manufacturing cost

Abstract

The invention discloses a stereotactic radiotherapy equipment isocenter calibration device, which comprises an isocenter ball mold assembly, a supporting assembly and a measuring device, and is characterized in that the isocenter ball mold assembly comprises an isocenter ball mold and a cylindrical supporting rod integrated with the isocenter ball mold; the supporting assembly is used for supporting the isocenter ball mold and the supporting rod; the measuring device rotates around the isocenter of the equipment in the first direction and swings along an arc in the second direction, the measuring device can rotate around the axis intersecting with the isocenter so as to measure the position of the isocenter of the radiotherapy equipment, and the isocenter calibration method of the stereotactic radiotherapy equipment is disclosed. The operation method is simple, the position of the isocenter can be quickly determined under the condition that the treatment head does not emit ray beams in the radiotherapy equipment installation and debugging stage, and the radiotherapy equipment installation and debugging efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a center calibration device and method for stereotactic radiotherapy equipment and the like. Background technique [0002] The treatment head of the new stereotactic radiotherapy equipment has a rotating drum, and the treatment head with a ray emission device is installed on the drum to rotate synchronously with the drum. The intersection of rays moving to different positions is the isocenter of the radiotherapy equipment. During the installation and commissioning of the radiotherapy equipment, the treatment head does not emit a ray beam, so the position of the isocenter cannot be found by the naked eye, and only after the radiotherapy equipment is all installed. The position of the isocenter is determined by the photosensitive method, which will affect the installation and debugging efficiency of the radiotherapy equipment and increase the manufacturing cost.
