摘要
对胸腹部肿瘤放疗患者,个体化考虑呼吸运动影响决定PTV范围和治疗计划是非常必要的。根据我院放疗中心实际情况研制了一种具有"度量"功能的基准标尺板,能有效地测定随生理呼吸致肿瘤靶区位移的测定,并介绍了这种标尺板的制作与临床应用。
To every chest-belly tumor patient receiving radiotherapy,it is necessary to consider that breathe movement would effect the PTV（plan target volume） range and radiotherapy plan.A kind of graticule that can measure the target region displacement with the physiology breathe was made according to the current conditions of radiation oncology center.The manufacturing methods and clinical practice of this graticule was reported in this article.
