摘　　要：放射治疗中作射野位置验证时,目前多是利用射野照相底片中,以照射野内及周围的组织结构作为参照,用肉眼与放射治疗计划的照射野作比对,故存在着较大的误差。笔者研制了一种具有“度量”功能的基准标尺板,能有效地减小这种比对误差。本文介绍了这种标尺板的制作与临床应用。Examining thing position of radiation therapy, we usually compare, th position that refers to the radiotherapy plan in to irradiation field in radiograph prevent these errors, a graticule is made, which can measure accurately. In thi plication of the graticule will be described in detail. e organization structure around and the with our eyes. It may cause error, To s text, the facture and the clinical application of the graticule will be described in detail.
