“…Other than the increased sensitivity mentioned earlier, the RCC system can obtain the measurement of the output level, i.e., the signal at d max , whereas for the Geske monitor alone a change in the output signal cannot be distinguished from a shift in beam energy. 5 With the RCC system individual parameters can be easily measured, as well as any custom-designed measurement condition, such as other two-depth ratios, off-axis measurements or even a complete depth-dose curve measurement. In fact, we have prepared a comprehensive set of aluminum disks to accommodate various measurement configurations.…”
