Developing a Phantom for the Positronium Imaging Evaluation
Acta Physica Polonica B Proceedings Supplement, 2022 In this contribution, a concept for a new phantom for positronium imaging with PET scanners is described. The proposed phantom is based on the NEMA IEC phantom in which six high-activity spheres are filled with solutions characterized by a different mean ortho-positronium lifetime.

Materials for phantoms for terahertz pulsed imaging [PDF]
Physics in Medicine and Biology, 2004 Phantoms are commonly used in medical imaging for quality assurance, calibration, research and teaching. They may include test patterns or simulations of organs, but in either case a tissue substitute medium is an important component of the phantom. The aim of this work was to identify materials suitable for use as tissue substitutes for the relatively
