Abstract
The invention discloses a radiation field control device and radiotherapy equipment. Two or more different-sized light limiting barrels are directly machined on a light limiting barrel support, or two or more light limiting barrel mounting portions are arranged on the light limiting barrel support, then the two or more light limiting barrels are respectively mounted in the light limiting barrel mounting portions in a one-to-one correspondence manner, any one of the light limiting barrels can move to a working position through a light limiting barrel switching device, in this case, when the light limiting barrel having suitable size is required, the unsuitable light limiting barrel does not need to be detached, and the required light limiting barrel can be used conveniently and quickly by directly controlling the light limiting barrel switching device. By adopting the solution, the radiation field control device is not only simple in structure, convenient and quick to use, but also greatly improves the working efficiency.
