Researchers at Dartmouth are investigating on a new phenomenon called Cherenkov radiation to see whether it can be used as a tool for measuring the radiation dose delivered to different tissues during radiotherapy.
Cherenkov radiation is emitted when electrons are fired through water at a speed faster than the speed with which light travels in water.

The team identified that the emitted Cherenkov radiation indicates the dose delivered by X-ray photons. Interventional radiologists can affirm the exact amount of therapy delivered to treatment sites in the near future.
The Dartmouth team concluded that the light emission suits x-ray photons is narrow beam stereo tactic radiation therapy, surgery validation studies, verification of dynamic intensity-modulated and volumetric modulated arc therapy treatment plans in water tanks near mono-energetic sources.

Single Photon Emission Computed Tomography, a nuclear imaging diagnostic tool helps in accurate assessment of blood flow to organs. It scans images for diagnosis of heart disease and abnormalities.
Cherenkov emission was found to be only suitable for surface dosimetry applications for electron use. A fundamental lack of Cherenkov emission at the Bragg peak, for proton dosimetry, makes the technique of little use, although investigators say that post-irradiation detection of light emission from radioisotopes could prove to be useful.
