Simulation of beam record data for 4D dose calculation
Treatment of moving targets can result in local over and under dosage due to interference effects of the beam application and the motion of the target. First experimental studies [1] as well as theoretical works [2, 3] showed that multiple irradiations with an accordingly reduced dose per irradiation reduce these inhomogeneities due to averaging effects. If the multiple irradiations are perform...
متن کاملMO-A-213AB-04: Verification of 4D Dose Delivery Using 4D Digital Human Phantom.
PURPOSE At present, techniques of 4D dose verification in radiation therapy for lung cancers associated with respiratory motion are very limited, due to either lack of patient anatomy or breathing information. The aim of this study is to develop a 4D dose verification technique based on XCAT phantom which incorporates both patient anatomy and respiratory mechanics. MATERIALS AND METHODS The 4...
متن کاملAn Integrated Simulation System Based on Digital Human Phantom for 4D Radiation Therapy of Lung Cancer
Purpose: To develop and test an integrated simulation system based on the digital Extended Cardio Torso (XCAT) phantom for 4-dimensional (4D) radiation therapy of lung cancer. Methods: A computer program was developed to facilitate the characterization and implementation of the XCAT phantom for 4D radiation therapy applications. To verify that patient-specific motion trajectories are reproducib...
متن کاملDose distribution and dosimetry parameters calculation of MED3633 palladium-103 source in water phantom using MCNP
Background: Palladium-103 (103Pd) is a brachytherapy source for cancer treatment. The Monte Carlo codes are usually applied for dose distribution and effect of shieldings. Monte Carlo calculation of dose distribution in water phantom due to a MED3633 103Pd source is presented in this work. Materials and Methods: The dose distribution around the 103Pd Model MED3633 located in the center of 30×...
متن کاملA design of a DICOM‐RT‐based tool box for nonrigid 4D dose calculation
The study was aimed to introduce a design of a DICOM-RT-based tool box to facilitate 4D dose calculation based on deformable voxel-dose registration. The computational structure and the calculation algorithm of the tool box were explicitly discussed in the study. The tool box was written in MATLAB in conjunction with CERR. It consists of five main functions which allow a) importation of DICOM-R...
