Supplementary Material

This movie shows the visualization of the 3D ultrasound fetus, including the original image displaying and the denoised results by our algorithm. baby.428x354x209.raw is the original volume data. The CUDA_denoised_baby_Rx.raw is the denoised data by our algorithm with the reference window radius of x. The X, Y and Z sliders are used to control the clipping of the objects to remove the background. The line chart on the lower left corner is the transfer function adjusting module. The first display mode is the mode with pseudo color. The second display mode is the mode with both pseudo color and light. The third display mode is the mode of gray level.
