Grid: A location dependent intensity modulated radiotherapy for bulky tumors
Background: An effective method for management of large and bulky malignant tumors. This treatment modality is also known as Specially Fractionated Radiation Therapy (SFRT). In this treatment technique a grid block converted the open radiation field into a series of pencil beams. Dosimetric characteristics of an external beam grid radiation field have been investigated using experimental and Mo...
متن کامل3D dose reconstruction in external beam radiotherapy using portal imaging
The verification of the dose delivered to a patient during radiation therapy is a particularly important step for ensuring treatment quality. This step, known as in vivo dosimetry can be realized using a bidimensional dosimeter named Electronic Portal Imaging Device (EPID). However, few methods enable the determination of an accurate and fully personalized 3D dose distribution for the most curr...
متن کاملA Simulation Study on Patient Setup Errors in External Beam Radiotherapy Using an Anthropomorphic 4D Phantom
Introduction Patient set-up optimization is required in radiotherapy to fill the accuracy gap between personalized treatment planning and uncertainties in the irradiation set-up. In this study, we aimed to develop a new method based on neural network to estimate patient geometrical setup using 4-dimensional (4D) XCAT anthropomorphic phantom. Materials and Methods To access 4D modeling of motion...
متن کاملThe comparison between 6 MV Primus LINAC simulation output using EGSnrc and commissioning data
Introduction: Monte Carlo calculation method is considered to be the most accurate method for dose calculation in radiotherapy. The purpose of this research is comparison between 6 MV Primus LINAC simulation output with commissioning data using EGSnrc and build a Monte Carlo geometry of 6 MV Primus LINAC as realistically as possible. The BEAMnrc and DOSXYZnrc (EGSnrc package) M...
متن کاملComprehensive 3D Visual Simulation for Radiation Therapy Planning
External beam radiation therapy is concerned with the precise and accurate delivery of radiation for cancer treatment. Highly-collimated beams are generated in a linear accelerator, consisting of several hardware components that move around the patient in a complex geometry to allow radiation target the tumor from every possible angle. The complex arrangements of the hardware components may giv...
