Parallel computation of mutual information on the GPU with application to real-time registration of 3D medical images

Shams, Ramtin; Sadeghi, Parastoo; Kennedy, Rodney; Hartley, Richard


Due to processing constraints, automatic image-based registration of medical images has been largely used as a pre-operative tool. We propose a novel method named sort and count for efficient parallelization of mutual information (MI) computation designed for massively multi-processing architectures. Combined with a parallel transformation implementation and an improved optimization algorithm, our method achieves real-time (less than 1. s) rigid registration of 3D medical images using a...[Show more]
