3D tumor localization through real-time volumetric x-ray imaging for lung cancer radiotherapy
3D tumor localization through real-time volumetric x-ray imaging for lung cancer radiotherapy
Recently we have developed an algorithm for reconstructing volumetric images and extracting 3D tumor motion information from a single x-ray projection. We have demonstrated its feasibility using a digital respiratory phantom with regular breathing patterns. In this work, we present a detailed description and a comprehensive evaluation of the improved …
