Stereotactic Body Radiation Therapy

Part of the book series: Medical Radiology ((Med Radiol Radiat Oncol))

Abstract

Stereotactic body radiation therapy (SBRT) treatments are characterized by high dose conformality to the target with steep dose gradients, so even slight patient misalignment from patient simulation to treatment could lead to a geographical miss resulting in underdosing of the target or overdosing of organs at risk (OARs). The role of the numerous imaging modalities available for SBRT treatments is crucial for precise delivery of radiation treatments. Furthermore, many treatment delivery techniques are available and may prove advantageous for site-specific SBRT treatments. In recent years, image guidance has matured sufficiently to allow acquisition of volumetric image data sets by treatment machines with the patient in the treatment position and then use registration techniques to automatically or manually align and shift the patient to the planned treatment position. This chapter discusses the use of the Tomotherapy Hi-Art® machine, which delivers Helical Tomotherapy Intensity Modulated Radiation Therapy (IMRT) and uses built-in megavoltage computerized tomography (MVCT) for Image-Guided Radiation Therapy (IGRT).
