PURPOSE A planning study was performed to evaluate the performance of volumetric modulated arc radiotherapy on head and neck cancer patients. Conventional fixed field IMRT was used as a benchmark. METHODS AND MATERIALS CT datasets of 29 patients with squamous cell carcinoma of the oro-pharynx, hypo-pharynx and larynx were included. Plans for fixed beam(More)
BACKGROUND A study was realised to evaluate and determine relative figures of merit of a new algorithm for photon dose calculation when applied to inhomogeneous media. METHODS The new Acuros XB algorithm implemented in the Varian Eclipse treatment planning system was compared against a Monte Carlo method (VMC++), and the Analytical Anisotropic Algorithm(More)
PURPOSE To assess the clinical impact of the Acuros XB algorithm (implemented in the Varian Eclipse treatment-planning system) in non-small-cell lung cancer (NSCLC) cases. METHODS AND MATERIALS A CT dataset of 10 patients presenting with advanced NSCLC was selected and contoured for planning target volume, lungs, heart, and spinal cord. Plans were created(More)
A comparative study was performed to reveal differences and relative figures of merit of seven different calculation algorithms for photon beams when applied to inhomogeneous media. The following algorithms were investigated: Varian Eclipse: the anisotropic analytical algorithm, and the pencil beam with modified Batho correction; Nucletron Helax-TMS: the(More)
PURPOSE A treatment planning study was performed to evaluate the performance of the novel volumetric modulated single arc radiotherapy on cervix uteri cancer patients. Conventional fixed field IMRT was used as benchmark. METHODS AND MATERIALS CT datasets of eight patients were included in the study. Plans were optimised with the aim to assess organs at(More)
BACKGROUND To report results in terms of feasibility and early toxicity of hypofractionated simultaneous integrated boost (SIB) approach with Volumetric Modulated Arc Therapy (VMAT) as adjuvant treatment after breast-conserving surgery. METHODS Between September 2010 and May 2011, 50 consecutive patients presenting early-stage breast cancer were submitted(More)
PURPOSE To assess the impact of volumetric modulated arc therapy (VMAT) with flattening filter free (FFF) beams for stereotactic body radiotherapy (SBRT) in inoperable stage I NSCLC. Current data were compared against a cohort of patients previously treated with advanced conformal techniques (3DCRT) based on conformal arcs. METHODS AND MATERIALS From July(More)
PURPOSE A treatment planning study was performed to compare volumetric-modulated arc radiotherapy against conventional fixed field IMRT. MATERIALS AND METHODS CT datasets of 10 patients affected by carcinoma of the anal canal were included and five plans were generated for each case: fixed beam IMRT, single (RA1)- and double (RA2)-modulated arcs with the(More)
PURPOSE A planning study was performed to evaluate RapidArc (RA), a volumetric modulated arc technique, on malignant pleural mesothelioma. The benchmark was conventional fixed-field intensity-modulated radiotherapy (IMRT). METHODS AND MATERIALS The computed tomography data sets of 6 patients were included. The plans for IMRT with nine fixed beams were(More)
PURPOSE A study was performed comparing dosimetric characteristics of volumetric modulated arcs (RapidArc, RA) and fixed field intensity modulated therapy (IMRT) on patients with bilateral breast carcinoma. MATERIALS AND METHODS Plans for IMRT and RA, were optimised for 10 patients prescribing 50 Gy to the breast (PTVII, 2.0 Gy/fraction) and 60 Gy to the(More)
