Model 430
The Gammex 430 is an instrument used to analyze the alignment of a linear accelerator. It is recommended that beam
alignment tests be completed at least once a year to determine the following problem situations:
?Displaced focal spot
?Asymmetric collimators
?Non-intersection of the collimator and gantry axes
?Lack of gantry arm support
The Gammex 430 complies with the alignment requirements of AAPM Task Group 40.
