Image-guided radiation therapy (IGRT) in gastrointestinal tumors.
CONTEXT Daily setup errors and changes in body habitus during external beam radiotherapy can result in interfraction variation, contributing to uncertainties in treatment delivery. The conventional method of patient positioning using external skin markings is inadequate in reducing these interfraction variations. OBJECTIVE To evaluate use of on-board imaging with daily kV-kV image matching to...
متن کاملAnalysis of Hip Joint Dose in Prostate Cancer Radiation Therapy: A Dosimetric Comparison of Treatment Plans
Background and purpose: Radiation therapy as a part of cancer treatment is used in almost 50-60% of involved cases. In prostate cancer radiation therapy, a large volume of pelvis is irradiated, so, it is necessary to preserve sensitive organs around the treatment area, especially rectum and bladder. In this study, some dosimetric parameters such as minimum dose (Dmin), maximum dose (Dmax), mean...
متن کاملMolecular PET/CT imaging-guided radiation therapy treatment planning.
The role of positron emission tomography (PET) during the past decade has evolved rapidly from that of a pure research tool to a methodology of enormous clinical potential. (18)F-fluorodeoxyglucose (FDG)-PET is currently the most widely used probe in the diagnosis, staging, assessment of tumor response to treatment, and radiation therapy planning because metabolic changes generally precede the ...
متن کاملImage Guided Radiation Therapy
An overview of Intensity Modulated Radiation Therapy (IMRT), a true revolution in the field of radiation oncology in that it provides the unprecedented means of conforming to the shape of the target tissues in 3-dimensions, reducing the risk of complications thereby improving the quality of life of irradiated patients. Moreover, IMRT provides the means to deliver higher than conventional doses ...
متن کاملImage Guided Radiation Therapy
With increasing emphasis on reducing the volume of radiation therapy fields while maintaining or improving precision of treatment and reducing radiation-related normal tissue toxicity, treatment position verification and correction before delivering radiotherapy had gained major importance. A variety of techniques have been developed that can accomplish this goal with aplomb, albeit each with i...
