Witryna2 dni temu · However, radiotherapy is also associated with a wide spectrum of radiation-induced toxicities which reduces quality of life. 1 Technological advances, such as intensity modulated radiotherapy (IMRT), volumetric modulated arc therapy (VMAT), image guided radio therapy (IGRT) and intensity modulated proton therapy (IMPT) … Witryna29 mar 2024 · Intervention / Treatment Radiation: Hypofractionated Pencil-Beam Scanning Intensity-modulated Proton Therapy Device: MEVION S250i Hyperscan and Adaptive Aperture Proton Therapy Machine Study Type Interventional Enrollment (Anticipated) 20 Phase Not Applicable Contacts and Locations
WitrynaThe treatment plans for IMRT and IMPT were both generated using the Treatment Planning System (TPS) of Eclipse (Varian Medical System, Inc., California, USA). The IMPT plans used two en-face beam angles and the IMPT with pencil beam weights was obtained through robust single-field optimization (SFO) technique. WitrynaImage-guided radiation therapy (IGRT) is the process of performing imaging before daily radiotherapy, with the intent of improving target accuracy and precision by correcting for geometric and anatomic deviations. IGRT techniques consist of planar or volumetric imaging, which allows for tighter treatment margins.
Witryna1 gru 2024 · Intensity-modulated proton therapy (IMPT) has the potential to reduce radiation dose to normal organs when compared to intensity-modulated radiation therapy (IMRT). We hypothesized that IMPT is associated with a reduced rate of cardiopulmonary toxicities in patients with Stage III NSCLC when compared with IMRT.
