Megavoltage X-Ray Imaging Based on Cerenkov Effect: A New Application of Optical Fibres to Radiation Therapy
Figure 2
X-ray spectra used in the simulation. The entrance spectrum was generated by a treatment planning system (Pinnacle3, Philips), and the exit spectra of X rays were simulated by passing the incident beam (with the entrance spectrum) through a 30 cm thick water phantom.
