Скачать или смотреть An Approach to improve accuracy of optical tracking systems in cranial radiation therapy

The combination of high acquisition rates with high accuracy has made optical tracking systems more and more popular for a wide range of medical applications. Especially in radiation therapy, tracking systems provide a high potential to replace conventional immobilization techniques and x-ray based localization systems to minimize the radiation dose. Although, a lot of commercial systems for surface recognition are available, a target localization accuracy in sub-millimeter range has not been achieved yet.
Our research is focused on the development of a non-invasive marker-less optical tracking system for cranial radiation therapy. For this purpose we want to combine 3D surface information using a commonly used triangulation technique with tissue thickness information from a novel optical technique. Here, we present first 4D-tomograms from three human foreheads.
