Technical status of the 3DOMC system for therapy of moving tumours

چکیده
Since 1997 cancer patients with localized tumours in the head, neck, and pelvis region were treated at the therapy unit at GSI by applying the rasterscan technique with scanned carbon ion beams [1]. In order to treat moving tumours feasibility studies have been performed, and basic functionality has been proven for lateral and longitudinal compensation separately [2,3,4]. The prototype 3DOMC system employs the raster scanner for lateral target motion compensation and a range shifter to adapt the Bragg peak position longitudinally [2,4]. In 2007 the prototype system was upgraded and integrated in the therapy control system (TCS) at GSI. In this report the technical status of the current 3DOMC system is described.

Technical status of the real-time beam tracking system
For intra-fractionally moving tumours such as lung cancer, treatments with scanned particles [1] without motion compensation can cause unacceptable local underor over-dosage due to interplay effects of sequential dose delivery and target motion [2]. In order to treat moving tumours with scanned particle beams, a beam tracking system, 3DOMC system, was developed [3] and upgraded [4,5]. The beam ...
