Today, conformality in radiotherapy is at the centre of many investments in equipment and staffing. To estimate the current situation within the European Organisation for Research and Treatment of Cancer (EORTC) conformal radiotherapy trial for prostate cancer, a technology questionnaire was designed to assess whether participating centres can comply with the required radiotherapy procedures of EORTC trial 22991, where a high dose is prescribed to the prostate. Questions covered various items of computed tomography, data acquisition, treatment planning, delivery and verification. All centres (n=31) replied to the questionnaire. All generate beam's eye views and dose volume histograms. All, but two, centres use digitally reconstructed radiographs to display images. The vast majority of the centres perform at least weekly treatment verification and half have access to individual in vivo dosimetry. The results of the questionnaire indicate that participating centres have access to the equipment and apply the procedures that are essential for conformal prostate radiotherapy. The technology questionnaire is the first step in the extensive quality assurance programme dedicated to this high-tech radiotherapy trial.
如今，放射治疗中的适形性是许多设备和人员投资的核心。为评估欧洲癌症研究与治疗组织（EORTC）前列腺癌适形放射治疗试验的当前情况，设计了一份技术调查问卷，以评估参与中心是否能够遵守EORTC 22991试验所需的放射治疗程序，该试验对前列腺规定了高剂量。问题涵盖计算机断层扫描、数据采集、治疗计划、交付和验证的各个项目。所有中心（n = 31）都回复了问卷。所有中心都生成射野方向观和剂量体积直方图。除了两个中心外，所有中心都使用数字重建射线照片来显示图像。绝大多数中心至少每周进行一次治疗验证，半数中心能够进行个体体内剂量测定。问卷结果表明，参与中心能够使用相关设备并应用适形前列腺放射治疗所必需的程序。这份技术调查问卷是致力于这项高科技放射治疗试验的广泛质量保证计划的第一步。
