Taking advantage of the renewal of a linear accelerator, the Radiation Therapy Department of the Centre Léon Bérard implemented, in collaboration with Philips Systèmes Médicaux, a conformal therapy set-up procedure using CT-scan for 3D treatment planning and a multileaf collimator that allows achievement of numerous irregular-shaped beams via the multileaf preparation system. The various elements of this equipment make possible well defined and structured procedures for treatment planning with different steps and essential tools used by this technique. We describe the means used and indicate future improvements that will lead to automation in order to provide good quality assurance, better security and substantial time saving. During the first year, 115 patients were treated with this new technique. They presented with central nervous system tumors (32 patients), lung cancer (29 patients), prostate cancer (20 patients), paranasal sinus tumors (14 patients) and tumors located in other sites (13 patients with soft sarcoma, hepato-bilary tumor, etc).
利用直线加速器的更新，里昂贝拉尔中心放疗科与飞利浦医疗系统公司合作，实施了一种适形治疗设置程序，该程序使用CT扫描进行三维治疗计划，并使用多叶准直器，通过多叶准备系统实现多种不规则形状的射束。该设备的各个部件使得治疗计划能够采用定义明确且结构化的程序，这些程序包含不同步骤以及该技术所使用的基本工具。我们描述了所采用的方法，并指出了未来将实现自动化的改进措施，以便提供良好的质量保证、更高的安全性并大幅节省时间。在第一年，115名患者接受了这项新技术的治疗。他们患有中枢神经系统肿瘤（32例）、肺癌（29例）、前列腺癌（20例）、鼻窦肿瘤（14例）以及位于其他部位的肿瘤（13例，包括软组织肉瘤、肝胆肿瘤等）。
