METHODS
Measurements were made on polystyrene eye phantom placed
in a wax head phantom.
RESULTS
The results of GAFCHROMIC® EBT film were 13% lower
than the results using BEBIG plaque simulator. This can be
attributed to the facts that the model eye does not reflect the
human eye exactly and that our measurement devices are inadequate.
CONCLUSION
The BEBIG treatment planning computer can be used considering
the shortcomings with respect to the first few mm and remote
off-axis points. Furthermore, dose verification in patients
can be made using GAFCHROMIC® EBT film on a model eye
phantom.
