METHODS
The measurements were performed for quality index (TPR20/10), percentage depth dose (PDD), beam profiles for open fields, output, wedge out-put factors. The measurement data were compared with the standard values and the ones used.
RESULTS
Adjusted TPR20/10 values were found to be changing within at most 0.6% with BJR Sup. 25 data and PDD, out-put, dose profiles and wedge filter transmissions were found to be changing within at most 2% with BJR Supplement 25 data.
CONCLUSION
The results of the measurements performed following all magnetron replacements were found to be not exactly the same but within acceptable limits.
