The AS350 is an automated dosimetry system designed for radiotherapy quality assurance. Combining a compact water phantom with the XBeam software platform, the system enables automated point-dose and Percentage Depth Dose (PDD) measurements through an integrated workflow for data acquisition, analysis, and curve generation.
The AS350 supports output calibration, depth-dose evaluation, and routine quality assurance procedures, helping users improve measurement efficiency while maintaining accuracy and reproducibility.
Compatible with
-
Absolute Dose Measurement and Automated PDD Acquisition:
