Abstract :
Digitally Reconstructed Radiograph has been widely used in 2D-3D image registration. This paper adopted an improved method which optimizes the parallelization on GPU to accelerate DRR generation. A cubic window is proposed to preprocess the object data, which helps accelerate the DRR generation. According to the Cuda-based experimental results, the improvement is quite obvious and the image quality is acceptable.
