摘要：
The paper describes a novel GPU implementation of the nonlinear coherent diffusion (NCD) algorithm for speckle reduction in ultrasound (US) images. Although the NCD algorithm gives satisfactory results, its execution in the CPU is too slow for real-time applications typical for US images. The use of parallel computing in the GPU allowed us to reduce the processing time of a single iteration of the diffusion to 85.8 ms for an image of size 512 * 1024 pixels.
