There are currently no guidelines for prescribing and reporting radiation therapy (RT) with ion beams. In this paper an overview over some technical aspects and their implication on ion RT are reported. This includes a discussion of the difference in the treatment planning systems currently used for active and passive beam shaping systems, aspects of patient positioning and target definition and dose prescription. Special emphasis is put on the questions arising from the use of the beam scanning methods in combination with biological treatment plan optimization, which is used in the German heavy ion therapy facility at GSI and will also be introduced at the hospital based facility in Heidelberg. Furthermore, the Heidelberg approach for the clinical dose prescription is compared with the methods developed at HIMAC in Chiba, Japan.
目前尚无关于离子束放射治疗（RT）的处方和报告指南。本文报告了一些技术方面及其对离子放射治疗的影响的概述。这包括对当前用于主动和被动束流整形系统的治疗计划系统差异的讨论、患者定位和靶区定义以及剂量处方等方面。特别强调了与生物治疗计划优化相结合使用束流扫描方法所产生的问题，这种方法在德国GSI的重离子治疗设施中使用，也将在海德堡的医院设施中引入。此外，还将海德堡的临床剂量处方方法与日本千叶市HIMAC开发的方法进行了比较。
