Abstract :
Abstract : In a small number of fractions, stereotactic body radiation therapy (SBRT) applies extremely high and conformal radiation doses to clearly defined targets in the chest, abdomen, or paraspinal regions. These doses are not homogeneous and have small or no margins, which makes them ideal for treating potentially heterogeneous and physiologically moving targets. A comprehensive evaluation of objectives and resource allocation is necessary before embarking on SBRT, which demands a substantial investment of staff and equipment. The SBRT delivery system is designed to integrate and regulate all treatment phases to the highest degree feasible, ensuring accurate SBRT delivery. For assistance on how to implement each phase of SBRT, there are a variety of resources available, including as reports from the American Association of Physicists in Medicine (AAPM) Task Group, practice recommendations from the American College of Radiology (ACR), and white papers from the American Society for Radiation Oncology (ASTRO). Imaging to define the target, immobilisation, simulation, planning, motion control, alignment imaging, and beam delivery are the phases. Following the quality assurance program's guidelines, qualified staff apply the necessary equipment at each stage of the treatment delivery process utilising procedures created during deployment. Planning, allocating resources (including human and material), providing training, developing protocols, and conducting continuing quality assurance (QA) at every stage of treatment delivery are all necessary for an SBRT programme to be successfully implemented. Imaging, simulation, planning, motion management, image-guidance, and treatment administration are all parts of SBRT that can be aided by well-established tools. A good SBRT programme can be achieved by understanding and following that guidelines.
