A Filtered Backprojection Algorithm with Characteristics of the Iterative Landweber Algorithm

Invention SummaryA new algorithm has been developed based on Filtered Back-Projection (FBP), but included is a control parameter k that gives an equivalent result to that of the kth iteration of the Landweber algorithm. With that said, the algorithm can be used in all image modalities that use FBP/iterative 3D image reconstruction algorithms: X-ray...

A Non-Iterative Image Deblurring Method to Compensate for a Non-Stationary Point Response Function

Invention Description: In many imaging applications, especially in nuclear medicine such as SPECT (single photon emission computed tomography) and PET (positron emission tomography), the images are blurred due to finite detector resolution. This invention is a fast, non-iterative algorithm to de-blur the image that is suffered from non-stationary...
