Abstract

The invention provides a detection device for the uniformity of a light field and a radiation field. A square flat board serves as a main body and comprises the upper portion, the middle body and the lower portion. The upper portion and the lower portion are respectively an organic glass shell. The upper portion is provided with at least one light field frame. The upper shell is provided with symmetry axes and a direction marking hole, wherein the symmetry axes are perpendicular to each other. The middle body is a flat board provided with symmetry axes, a dimension marking hole and a direction marking hole, wherein the symmetry axes are perpendicular to each other. According to the detection device for the uniformity of the light field and the radiation field, as the dimension marking hole is formed in the middle marking board, the error of the light field and the radiation field of an exposed film can be directly read out from the middle marking board provided with the dimension marking hole, then the problem that time is consumed and labor is wasted when the light field and the radiation field are detected in the prior art can be solved effectively, and the accuracy of detection results is improved. Meanwhile, the detection device for the uniformity of the light field and the radiation field is simple in structure, practical and free of maintenance, and the defects that marks made for film exposure in the prior art are difficult to distinguish, errors occur easily, a high-energy accelerator CR sheet cannot be used, and a two-dimension ionization chamber is poor in matrix accuracy, high in price and high in maintenance cost can be overcome effectively.

Description

technical field [0001] The invention relates to a detection device of radiotherapy equipment, in particular to a detection device capable of conveniently and quickly realizing the consistency of the light field and radiation field. Background technique [0002] Radiodiagnosis and treatment equipment is currently widely used medical equipment. Among them, the light field refers to the area defined by the simulated light source on the incident surface of the ray device (accelerator, Co60 machine, etc.). The irradiation field, also known as the radiation field, refers to the projection of the ray beam on the incident surface, to be precise, the area defined by 50% of the dose intensity in the central area of ​​the beam. [0003] In clinical treatment and diagnostic examination, since the field of view cannot be determined visually, visible light is usually used to simulate the field of view. Consistency detection of shot field and light field is mainly to verify the coinciden...
