Object independent scatter sensitivities for PET, applied to scatter estimation through fast Monte Carlo simulation
Simon Noë, Seyed Amir Zaman Pour, Ahmadreza Rezaei +3
Scattered coincidences introduce quantitative bias in positron emission tomography (PET) and must be compensated during reconstruction. Conventional scatter estimates typically rel…
Improved energy-based scatter estimation by incorporating local energy spectra and accelerating the parametric fitting
Seyed Amir Zaman Pour, Ahmadreza Rezaei, Floris Jansen +3
PET requires accurate, precise, and efficient scatter correction techniques. Conventional scatter estimation typically relies on tail-fitted single-scatter simulation (SSS) strateg…
Joint estimation of activity, attenuation and motion in respiratory-self-gated time-of-flight PET
Masoud Elhamiasl, Frederic Jolivet, Ahmadreza Rezaei +5
Whole-body PET imaging is often hindered by respiratory motion during acquisition, causing significant degradation in the quality of reconstructed activity images. An additional ch…
Resolution enhancement, noise suppression, and joint T2* decay estimation in dual-echo sodium-23 MR imaging using anatomically-guided reconstruction
Georg Schramm, Marina Filipovic, Yongxian Qian +4
Purpose: Sodium MRI is challenging because of the low tissue concentration of the 23 Na nucleus and its extremely fast biexponential transverse relaxation rate. In this article, we…
Limited Angle Tomography reconstruction for non-standard MBI system by means of parallel-hole and pinhole optics
G. E. Poma, F. Garibaldi, F. Giuliani +9
The purpose of the present work is the study of reconstruction properties of a new Molecular Breast Imaging (MBI) device for the early diagnosis of breast cancer, in Limited Angle…
