Description
Yagiz Yedekci, Mehmet Fazıl Enkavi, and Ferah Yildiz present a medical physics study, published in 2026, on verifying radiation dose in cancer brachytherapy by watching it glow. In high dose rate brachytherapy a radioactive source sits inside the body, and steep dose gradients make checking the delivered dose hard. Their method images Cherenkov light, the faint glow charged particles make in water like material, boosted by a fluorescent dye.
Using a cobalt-60 source, whose photons carry more energy than the usual iridium source, the team calibrated glow brightness against absorbed dose in a custom printed phantom. Flat dose maps built from the glow were then checked against the treatment planning computer. The authors aim for real time, full field dose checks in the clinic.
