PARALLEL PROCESSING OF 3D MEDICAL IMAGE REGISTRATION BY GP-GPU

摘要

The present invention provides an adjustment technique of a medical image required to monitor diseases in the medical image obtained from a same patent at different times. According to the present invention, provided is a parallel processing method of a three-dimensional (3D) medical image adjustment using GP-GPU. The present invention is applied with parallel processing based on the GP-GPU in order to rapidly and accurately process 3D medical image data by gathering strengths of an existing division-based technique and a pixel-based technique.
