Abstract:
1. An image data processing component, comprising: algorithm memory including one or more image domain only iterative de-noising algorithms based on the Huber roughness penalty minimization; and a processor which de-noises reconstructed image data solely in the image domain based on at least one of the Huber roughness penalty iterative minimization algorithms which includes a first parameter that is a free variable and in a first term determines a strength of the de-noising and a second parameter that is a free variable and in a second term determined a smoothness of the de-noising, wherein the first term, which is based on the Huber roughness penalty minimization, includes a product of the first parameter and a weighted sum of neighboring voxels to a voxel adjusted for size that determines a strength of the de-noising.
