Abstract
Official abstract text for this publication.
A method for reducing noise in a medical diagnostic image includes acquiring an initial three-dimensional (3D) volume of projection data, generating a projection space noise estimate using the 3D volume of projection data, generating an initial 3D volume of image data using the 3D volume of projection data, generating an image space noise estimate using the 3D volume of image data, generating a noise projection estimate using the projection space noise estimate and the image space noise estimate, and reconstructing an image using the generated noise estimate. A system and non-transitory computer readable medium are also described.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for reducing noise in a medical diagnostic image, said method comprising: acquiring an initial three-dimensional (3D) volume of projection data; de-noising the initial 3D volume of projection data to generate a 3D set of de-noised projection data; generating an initial 3D volume of image data using the 3D set of de-noised projection data; generating a de-noised image volume using the initial 3D volume of image data; generating an estimated n…
