Tumor-treating-fields (TTFields) therapy uses alternating electric fields delivered via transducer arrays placed regionally close to the tumor site to non-invasively inhibit tumor growth. Although important insights into the mechanisms underlying the anticanc...

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 momentum and polarization. We evalu...

Real-time, high-precision monitoring of tumor anatomy and microenvironment remains a critical unmet need in radiotherapy. Recent experimental studies have demonstrated that 511 keV photon pairs produced during positron annihilation are quantum entangled. Here...
