ABSTRACT
Generation of digitally reconstructed radiographs (DDRs) is key to image-guided radiation therapy and widely used for 2D-3D image registration to verify the patient's position. The classic algorithms to generate DRRs with ray casting is time consuming to hamper the registration process. The authors describe the attempt to extend the light field rendering techniques from computer graphics, using the light field computed from ray casting to interpolate a DRRs image from a novel fixed viewpoint. Because most of the computation is performed in a preprocessing step, the speed is greatly accelerated and satisfactory DRRs can be obtained.
