Proton Flash Therapy-Induced Radioisotopes As a Source of Entangled 511 Kev Photons

Ultra-high dose rate (FLASH) proton therapy generates positron-emitting radioisotopes, including C-11, O-15, and F-18, which decay via β⁺ emission. Each annihilation produces a pair of 511 keV photons naturally entangled in momen...

Pycno: An Open-Source Python Framework for Computational Nuclear Oncology and Virtual Theranostic Trials

Computational nuclear oncology (CNO) methods are advancing rapidly but often developed in isolated tools and workflows that are difficult to reproduce, compare, and share. This fragmentation limits virtual studies and slows trans...

Quantifying Dual Energy Signal Hidden within Single Energy Noise

Neural networks have recently been demonstrated that convert single-energy CT images into dual-energy CT images. It seems at first that this “dual-energy conversion” is only possible using image priors: one might assert that if a...
