Abstract：This article introduced the design and application process of quality assurance (QA)
verification plates and beam field cross-link plates for radiotherapy. The QA plates and beam field cross
plates, which were composed of 2~3 mm lead sheaths and organic glasses, respectively possess the
function of radiotherapy QA verification film and the function of showing the beam field cross position.
The QA plates and beam field cross plates can be used for the QA detection of radiotherapy equipment
and the verification of radiotherapy location. This method solves problems in conventional IP plates and
X-ray film which cannot show beam field center. It can also reduce the cost of detection test for QA of
radiotherapy equipment. Thus, it has great clinical value in radiotherapy department.
