Commissioning of Kilo-voltage Cone Beam Computed Tomography for Image-guided Radiotherapy
kV-CBCT integrated with linear accelerators as a tool for IGRT, was developed to acquire online volumetric and anatomical images (Xing 2006). The successful implementation of CBCT requires a quality assurance (QA) program that not only involves robust and intuitive quality control checks of the equipment, but also thoughtful image-guidance processes based on measurement of positional uncertaint...
متن کاملRationale and Technology of Cone-beam Computed Tomography-based Image-guided Radiotherapy
Cone-beam Computed Tomography-based Image-guided Radiotherapy Variation of the target position is a major challenge in the clinical practice of external beam radiotherapy (EBRT). Variability of the tumour position from day to day is caused by breathing, changes of the filling of hollow organs and peristaltic or more complex changes of the anatomy of patients. If not corrected or compensated for...
متن کاملSU-F-BRCD-01: A Novel Dual Source Array Tetrahedron Beam Computed Tomography (TBCT) System for Image Guided Radiotherapy.
PURPOSE To design and test the feasibility of a novel dual source array, dual detector array TBCT system which is capable of both volumetric CT imaging as well as real-time stereoscopic x-ray imaging for image guided radiotherapy (IGRT). METHODS Besides producing improved image quality, the geometry of TBCT is also more compact and flexible. It is possible to mount two x-ray source arrays and...
متن کاملA new scheme for view-dependent data differentiation in fan-beam and cone-beam computed tomography.
In computed tomography, analytical fan-beam (FB) and cone-beam (CB) image reconstruction often involves a view-dependent data differentiation. The implementation of this differentiation step is critical in terms of resolution and image quality. In this work, we present a new differentiation scheme that is robust to changes in the data acquisition geometry and to coarse view sampling. Our scheme...
متن کاملDevelopment of a micro-computed tomography-based image-guided conformal radiotherapy system for small animals.
PURPOSE To report on the physical aspects of a system in which radiotherapy functionality was added to a micro-computed tomography (microCT) scanner, to evaluate the accuracy of this instrument, and to and demonstrate the application of this technology for irradiating tumors growing within the lungs of mice. METHODS AND MATERIALS A GE eXplore RS120 microCT scanner was modified by the addition...
