Latest Patents

Changhong Dai holds a patent for "In-reconstruction filtering for positron emission tomography (PET) list mode iterative reconstruction." This patent describes a system and method that iteratively reconstructs an image of a target volume of a subject. In each iteration, an estimated image of the target volume is forward projected and compared to received event data to determine a discrepancy. The discrepancy is then back projected, updating the estimate image. Notably, in at least one iteration, the estimate image is filtered in the image domain prior to being back projected. This innovative approach enhances the quality of PET imaging.
