1) Appreciate the breadth of IGRT technologies used in the radiation therapy treatment room. 2) Understand the different sources of uncertainty for different IGRT approaches. 3) Understand approaches to mitigating the limitations of different IGRT technologies.
There is a large variety of technologies available for image-guided radiation therapy (IGRT), including 2D projection x-ray imaging (kilovoltage (kV) and megavoltage (MV)), computed tomography (conventional, MV, and cone-beam), ultrasound, and radiofrequency emitting markers. There are also different methodologies for using these technologies, or combinations of these technologies. Each technology has its own uncertainties and limitations which should be well described and understood. Similarly, each technology has different approaches available for mitigating these uncertainties that need to be appreciated. In this presentation we will describe and compare the different technologies and IGRT approaches, and give an overview of the uncertainties involved in the use of each.
