A Cup of Water Counted Each Radiation Pulse
Cavity-enhanced optical sensing read clinical pulses in real time with a reported nominal 90-microgray resolution.
Summary
Cavity-enhanced optical sensing read clinical pulses in real time with a reported nominal 90-microgray resolution.
A proof-of-concept dosimeter uses a centimeter-scale volume of water as both a tissue-equivalent medium and an optical sensing element. Cavity-enhanced absorption measurements tracked individual clinical radiotherapy pulses in real time, with the authors reporting nominal single-pulse resolution of 90 microgray. They propose that the method could eventually be miniaturized and integrated with fiber optics for in-situ dose measurement. The current work is a laboratory demonstration, not a validated micron-scale clinical device or replacement for established treatment dosimetry.
