Validation of measurement‐guided 3D VMAT dose reconstruction on a heterogeneous anthropomorphic phantom
3DVH software (Sun Nuclear Corp., Melbourne, FL) is capable of generating a volumetric patient VMAT dose by applying a volumetric perturbation algorithm based on comparing measurement-guided dose reconstruction and TPS-calculated dose to a cylindrical phantom. The primary purpose of this paper is to validate this dose reconstruction on an anthropomorphic heterogeneous thoracic phantom by direct...
متن کاملValidation of fluence‐based 3D IMRT dose reconstruction on a heterogeneous anthropomorphic phantom using Monte Carlo simulation
In this study, we evaluated the performance of a three-dimensional (3D) dose verification system, COMPASS version 3, which has a dedicated beam models and dose calculation engine. It was possible to reconstruct the 3D dose distributions in patient anatomy based on the measured fluence using the MatriXX 2D array. The COMPASS system was compared with Monte Carlo simulation (MC), glass rod dosimet...
متن کاملMeasurement-Guided 4D VMAT Dose Reconstruction on an Arbitrary Homogeneous Dataset
IMRT/VMAT dosimetric verification historically was performed in a phantom replacing a patient on the treatment table. Ideally this should be a full volumetric measurement, but in practice only a limited number of points is typically sampled. The usual metric to quantify agreement with the TPS is the gamma index which combines dose-error and distance to agreement analysis components. While γ-ana...
متن کاملMeasurement of Entrance Surface Dose on an Anthropomorphic Thorax Phantom Using a Miniature Fiber-Optic Dosimeter
A miniature fiber-optic dosimeter (FOD) system was fabricated using a plastic scintillating fiber, a plastic optical fiber, and a multi-pixel photon counter to measure real-time entrance surface dose (ESD) during radiation diagnosis. Under varying exposure parameters of a digital radiography (DR) system, we measured the scintillating light related to the ESD using the sensing probe of the FOD, ...
متن کاملDevelopment of a physical 3D anthropomorphic breast phantom.
PURPOSE Develop a technique to fabricate a 3D anthropomorphic breast phantom with known ground truth for image quality assessment of 2D and 3D breast x-ray imaging systems. METHODS The phantom design is based on an existing computer model that can generate breast voxel phantoms of varying composition, size, and shape. The physical phantom is produced in two steps. First, the portion of the vo...
