Intensity-Modulated Radiation Therapy (IMRT) with Different Combinations of Treatment-Planning Systems and Linacs

Abstract

For the commissioning of IMRT systems, the whole chain from the TPS to the linac has to be investigated. Components that passed the commissioning in another clinical environment can have severe malfunctions when used in a new environment. Therefore, not only single components but the whole chain from planning to delivery has to be evaluated in commissioning and checked regularly for QA.

Multisegmented Tangential Breast Fields: a Rational Way to Treat Breast Cancer

“…MS-CRT is a good alternative to IMRT, while the quality control of IMRT is difficult [2,6,14]. Moreover, IMRT increases MU for large irradiated volumes relative to 3D-CRT.…”

Significance of Radiation Therapy for Adenocarcinomas of the Esophagus, Gastroesophageal Junction and Gastric Cancer with Special Reference to the MAGIC Trial

“…The radiation technique did not meet the highest standards. With three-dimensional conformal treatment planning and modern techniques the target volume can be individualized and the protection of normal tissue is increased [8,21,33,38,56]. Thus, acute radiation-induced toxicity can be minimized, and an adequate supportive care during radiochemotherapy permits intensified treatment [43].…”

Helical Tomotherapy as a New Treatment Technique for Whole Abdominal Irradiation

“…The purpose was to explore the potential of tomotherapy as a new method of image-guided intensity-modulated radiotherapy (IMRT) to lower the dose to kidneys, liver and bone marrow while covering the peritoneal cavity with a homogeneous dose [8,15,16,23,24]. With a field width of 40 cm and a maximal length of 160 cm, helical tomotherapy is a very promising option for this kind of large and complexly shaped target volumes [1,2,6,10,12,17,19]. We provide the first clinical report on the use of tomotherapy in large-field WAI.…”
