Purpose: We describe the design and use of a daily QA device for proton therapy. The device is designed for therapists to check the readiness of the IBA Proton Therapy System (IBA, Louvain-la-Neuve, Belgium) during morning QA. The checks include connectivity, positioning, mechanical, imaging and dosimetric parameters of the proton therapy system. M...
Article
Purpose: Quality assurance (QA) is essential in safe and accurate delivery of radiation therapy. However, QA in proton therapy is challenging due to complicated and often facility-specific beam delivery systems and limited beam time for QA. The purpose of this study is to develop an efficient and comprehensive QA procedure for a multi-room proton t...
Article
Purposes: A chair, coupled to a robotic patient positioning system (PPS) was manufactured to treat an intracranial tumor in a proton incline beam-line system. Treating patients in the seated position as accurately and efficiently as a treatment table requires the essential functions of isocentric rotation and a weight-sagging-correction algorithm f...
Article
Topic of interest: Clinical applications of AlignRT 3-cameras real-time surface image-guided positioning system (IGPS) for positioning patients to reduce the number of X-ray images and tracking intra-fractional movements in proton therapy.Purposes: To position patients and track the intra-fractional movements, the AlignRT system was implemented in...
Article
Purpose: Accurate determination of proton dose and penetration range is critical in proton therapy. The purpose of this study is to investigate the range and dosimetric calculation accuracy for a commercial proton therapytreatment planning system (TPS). Methods: A lamb leg and solid water plates were used as phantoms in this study. Radiochromic fil...
Article
Purpose: The Inclined Beam Line (IBL) is an innovative partial gantry design which provides two beam angles at 30 and 90 degrees with full flexibility of the patient positioning system of the gantry design. Compared to the full gantry design in proton therapy, the IBL is a simplified design allowing for less equipment maintenance, physics quality a...

... However, this results in a build-up of an anterior dose 11 , as shown in Fig. 1. Moreover, the dose distribution is sensitive to tissue density inhomogeneity, which results in range uncertainties 12 and potentially underirradiation of the tumour, or over-irradiation of healthy tissue 13 . ...
