Accurate 2D Reconstruction for PET Scanners based on the Analytical White Image Model
Tomislav Matulić, Damir Seršić
In this paper, we provide a precise mathematical model of crystal-to-crystal response which is used to generate the white image - a necessary compensation model needed to overcome…

Sampling and Reconstruction of Sparse Signals in Shift-Invariant Spaces: Generalized Shannon's Theorem Meets Compressive Sensing
Tin Vlašić, Damir Seršić
This paper introduces a novel framework and corresponding methods for sampling and reconstruction of sparse signals in shift-invariant (SI) spaces. We reinterpret the random demodu…

2D PET Image Reconstruction Using Robust L1 Estimation of the Gaussian Mixture Model
Azra Tafro, Damir Seršić, Ana Sović Kržić
An image or volume of interest in positron emission tomography (PET) is reconstructed from pairs of gamma rays emitted from a radioactive substance. Many image reconstruction metho…
