| Abstract:: |
| Objective To discuss the differences on the design and evaluation between the L-type and Z-type mazes of typical medical electric linear accelerator. Methods The study is conducted by choosing some typical medical electric linear accelerators used in China, further analyzing on the running conditions of the accelerators in the mode of MV-X-ray, and referring to the late NCRP Report 51 and other references.Results The radiation levels at the access to therapy room are effectively reduced by Z-type mazes.Conclusions The Z-type mazes are advisable during the optimization design. |
