Abstract

We developed a stereo-photogrammetry camera mounted system and assess its application as an imaging modality suitable for image-guided radiation therapy (IGRT). 2D clinical photography of visible disease is routinely employed to document tumor response and the side effects of treatment interventions. IGRT is the process of incorporating new patient imaging data into the radiation treatment course in order to make adjustments to daily treatment delivery parameters. Our system, which combines the two, resides within the head of a linear accelerator treatment machine, which lends its computer-controlled precision to acquire stereo pairs with millimeter accuracy. Our IGRT workflow is contained in our analysis.
