Methods for Positronium Lifetime Image Reconstruction

Abstract

Researchers at the University of California, Davis have developed a technology involving statistically reconstructing positronium (or positron) lifetime imaging (PLI) for use with a positron emission tomography (PET) scanner, to produce images having resolutions better than can be obtained with existing time-of-flight (TOF) systems.

Full Description

The technology leverages positron emission tomography (PET) scanners to provide reconstructed positronium lifetime imaging (PLI). It improves the scanning precision, allowing for noninvasive, clear imaging of tissue and enabling better medical treatment plans.

Applications

• Improves resolution, providing more precise imaging than existing TOF systems 
• Allows for noninvasive patient examination 
• Enables accurate identification of hypoxic regions in a human body 
• Compatible with existing PET scanners 
• Overcomes the lack of practical methods for imaging positronium lifetimes at high spatial resolutions 
• Improves upon the limitations of current PET imaging solutions that ignore the lifetime history of positrons

Features/Benefits

• Healthcare and medical imaging 
• Cancer staging and treatment planning 
• Development and enhancements of PET scanners
