An in vivo dosimetry system that uses p-type semiconductor diodes with buildup caps was characterized for clinical use. The dose per pulse dependence was investigated. This was done by altering the SSD, field size and wedge for photons, and by altering SSD and cone size for electrons. The off-axis correction and effect of changing repetition rate were also investigated. A model was made to fit the measured diode correction factors.
