Download or read book Techniques to Minimize the Dosimetric Impact of Intrafractional Motion with Improved Treatment Accuracy and Efficiency on a C arm Medical Linear Accelerator written by Cody Church and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stereotactic radiosurgery is a high-dose therapeutic technique for treating cranial lesions. To ensure that treatment is safe and effective several techniques are employed, namely: (1) Image guidance to ensure accurate patient positioning (e.g. pre-treatment cone-beam computed tomography); (2) Use of immobilization devices (e.g. invasive frames or non-invasive thermoplastic masks) that fixate the patient to the treatment couch during therapy. Despite these efforts, intra-fraction motion on the order of several millimetres or degrees can occur that could impact target coverage, and dose received to healthy tissues. This work aims to quantify the dosimetric impact of motion during radiosurgery and develop two methodologies for addressing motion: 1) megavoltage (MV) imaging with region of interest (ROI) apertures to detect and correct for motion with couch translations. 2) Dynamic couch trajectories to minimize treatment distances during delivery which could improve treatment efficiency, potentially minimizing the magnitude and/or frequency of motion.

Download or read book Accuracy Requirements and Uncertainties in Radiotherapy written by International Atomic Energy Agency and published by . This book was released on 2017-04-12 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accuracy requirements in radiation oncology have been defined in multiple publications; however, these have been based on differing radiation technologies. In the meantime, the uncertainties in radiation dosimetry reference standards have been reduced and more detailed patient outcome data are available. No comprehensive literature on accuracy and uncertainties in radiotherapy has been published so far. The IAEA has therefore developed a new international consensus document on accuracy requirements and uncertainties in radiation therapy, to promote safer and more effective patient treatments. This publication addresses accuracy and uncertainty issues related to the vast majority of radiotherapy departments including both external beam radiotherapy and brachytherapy. It covers clinical, radiobiological, dosimetric, technical and physical aspects.

Download or read book Stereotactic Radiosurgery for Prostate Cancer written by Michael J. Zelefsky and published by Springer. This book was released on 2018-09-28 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a comprehensive evaluation of the use of stereotactic body radiosurgery (SBRT) for the treatment of prostate cancer. The rationale, selection criteria, and treatment planning for prostate SBRT are explained. Important imaging and anatomic considerations are discussed, and detailed consideration devoted to organ motion and tumor tracking during SBRT. Outcomes of therapy are then examined, with thorough appraisal of side effect profiles and quality of life impacts. Clear guidance is provided on how to deliver the therapy in a way that minimizes the risk of long-term urinary and rectal toxicities. Stereotactic radiosurgery for prostate cancer is an increasingly used form of treatment. Retrospective investigations have demonstrated the safe application of high-dose treatments, with 5-year results comparable to those achieved with protracted external beam radiotherapy. Prospective studies are underway comparing SBRT with more traditional forms of image-guided and intensity-modulated radiotherapy. In offering in-depth guidance on safe delivery of prostate SBRT, this book will be of value for students of radiation oncology, more experienced practitioners, and medical physicists.

Download or read book Radiotherapy in Cancer Care written by International Atomic Energy Agency and published by . This book was released on 2017-11-28 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cancer treatment is complex and calls for a diverse set of services. Radiation therapy is recognized as an essential tool in the cure and palliation of cancer. Currently, access to radiation treatment is limited in many countries and non-existent in some. This lack of radiation therapy resources exacerbates the burden of disease and underscores the continuing health care disparity among States. Closing this gap represents an essential measure in addressing this global health equity problem. This publication presents a comprehensive overview of the major topics and issues to be taken into consideration when planning a strategy to address this problem, in particular in low and middle income countries. With contributions from leaders in the field, it provides an introduction to the achievements and issues of radiation therapy as a cancer treatment modality around the world. Dedicated chapters focus on the new radiotherapy technologies, proton beams, carbon ion, intraoperative radiotherapy, radiotherapy for children, treatment of HIV-AIDS malignancies, and costing and quality management issues.

This book was released on 2013-10-18 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third edition of Intensity Modulated Radiation Therapy was written to enhance the reader’s understanding of the cutting-edge technology of Intensity Modulated Radiation Therapy. It is designed to both update old readers and inform new readers about the complexities and details of clinical management. This completely updated edition provides a step-by-step, practical approach to the use of IMRT in the evaluation and treatment of cancer patients.
