Megavoltage X-Ray Imaging Based on Cerenkov Effect: A New Application of Optical Fibres to Radiation Therapy
Figure 4
Fluence-to-mean-dose-in-water conversion factors used in calculating the energy response of CPID. The mean dose in water is defined as the integral of depth-dose curve along the depth axis normalized to the thickness of the water slab. The calculations assume broad parallel beam of X rays incident normally on 18.67, 36.30, and 53.01 cm thick slabs of water in air.
