Fully three-dimensional reconstruction for a PET camera with retractable septa

D.W. Townsend , Antoine Geissbühler , Michel Defrise +5 more

A fully 3-D reconstruction algorithm has been developed to reconstruct data from a 16 ring PET camera (a Siemens/CTI 953B) with automatically retractable septa. The tomograph is...

An iterative thresholding algorithm for linear inverse problems with a sparsity constraint

Ingrid Daubechies , Michel Defrise , Christine De Mol

Abstract We consider linear inverse problems where the solution is assumed to have a sparse expansion on an arbitrary preassigned orthonormal basis. We prove that replacing the ...
