Survey on Medical Image Registration using Graphics Processing Unit

Medical Image registration is a preprocessing step for the medical images analysis which requires large computations when executed on sequential processors. To increase the execution speed, the registration process executed on the graphics processing unit which execute the registration process parallel. Registration process is divided into the parts in the form of kernels which are evaluated by using the different number of threads on GPU. In this paper we compare the results obtained from CPU and GPU to register the two medical images. The data set includes the MRI and CT scan images for the analysis which are taken at different times of same object or images of the different objects taken at the same time. This problem is basically formulated to minimize the cost function by implementing the process on the parallel platform. KeywordsGPU, Image Registration, MRI, CT, CPU.
