First Positronium Lifetime Imaging using Mn and Co with a plastic-based PET scanner

Manish Das, Sushil Sharma, Ermias Yitayew Beyene +45

Positronium Lifetime Imaging (PLI) extends positron emission tomography by using the lifetime of positronium atoms as a probe of tissue molecular architecture. In this work, we rep…

Studies of CPT symmetry in positronium decays with 192 plastic strip J-PET detector

N. Chug, S. D. Bass, E. Y. Beyene +40

A direct test of the CPT symmetry is performed for the electromagnetic decays of ortho-positronium using the J-PET tomograph. We present the precise measurement of the CPT-sensitiv…

Positronium Imaging: History, Current Status, and Future Perspectives

Paweł Moskal, Aleksander Bilewicz, Manish Das +11

Positronium imaging was recently proposed to image the properties of positronium atoms in the patient body. Positronium properties depend on the size of intramolecular voids and ox…
