A Radiometry tolerant method for direct 3D/2D registration of computed tomography data to X-ray images: Transfer function independent registration 
Abstract:
As exact dose delivery is essential for radiological cancer treatment, image-guided radiotherapy (IGRT) methods are used to estimate corrections of the tumor alignment. This is often done through comparison of a Computed Tomography (CT) to the patient alignment visible in digital radiography images (DRs) acquired from within the treatment device. Digitally Reconstructed Radiography Images (DRRs) computed from the CT are then geometrically registered to the DRs. A problem is that radiometric prop...    »
