Megavoltage X-Ray Imaging Based on Cerenkov Effect: A New Application of Optical Fibres to Radiation Therapy

Table 3

The total number of Cerenkov photons (that are generated in the detector and reach the AMFPI) per LINAC pulse (~0.026 cGy dose-to-water at the isocentre) for a 6 MV beam and various detector thicknesses. Statistical uncertainty for each value is ~0.8%.

Energy (MV)	𝑑=10 cm	𝑑=20 cm	𝑑=30 cm
