VMAT planning study in rectal cancer patients
BACKGROUND To compare the dosimetric differences among fixed field intensity-modulated radiation therapy (IMRT), single-arc volumetric-modulated arc therapy (SA-VMAT) and double-arc volumetric-modulated arc therapy (DA-VMAT) plans in rectal cancer. METHOD Fifteen patients with rectal cancer previously treated with IMRT in our institution were selected for this study. For each patient, three p...
متن کاملPhoton Optimizer (PO) prevails over Progressive Resolution Optimizer (PRO) for VMAT planning with or without knowledge‐based solution
The enhanced dosimetric performance of knowledge-based volumetric modulated arc therapy (VMAT) planning might be jointly contributed by the patient-specific optimization objectives, as estimated by the RapidPlan model, and by the potentially improved Photon Optimizer (PO) algorithm than the previous Progressive Resolution Optimizer (PRO) engine. As PO is mandatory for RapidPlan estimation but o...
متن کاملEvaluation and comparison of New 4DCT based strategies for proton treatment planning for lung tumors
PURPOSE To evaluate different strategies for proton lung treatment planning based on four-dimensional CT (4DCT) scans. METHODS AND MATERIALS Twelve cases, involving only gross tumor volumes (GTV), were evaluated. Single image sets of (1) maximum intensity projection (MIP3) of end inhale (EI), middle exhale (ME) and end exhale (EE) images; (2) average intensity projection (AVG) of all phase im...

4D VMAT, gated VMAT, and 3D VMAT for stereotactic body radiation therapy in lung.
Four-dimensional volumetric modulated arc therapy (4D VMAT) is a treatment strategy for lung cancers that aims to exploit relative target and tissue motion to improve organ at risk (OAR) sparing. The algorithm incorporates the entire patient respiratory cycle using 4D CT data into the optimization process. Resulting treatment plans synchronize the delivery of each beam aperture to a specific ph...
