Claim One:
1. A radiation therapy system, comprising: a real-time 3D imaging unit which generates a baseline and real-time 3D images of at least a portion of a subject body region including a target and one or more Organs At Risk (OARs); a registration unit which deformably registers a planning image of the subject body region and the baseline image, and maps radiation absorptive properties of tissue in the planning image to the baseline image; a motion unit which measures motion of the target volume and OARs during radiation therapy treatment based on the real-time images; and a real-time dose computation engine which computes a real-time radiation dose delivered to the target and OARs based on the tissue radiation absorptive properties mapped from the baseline image or planning image onto the real-time 3D images.
