The AS450 is a compact three-dimensional water phantom scanning system designed for beam characterization and radiotherapy quality assurance. Featuring a lightweight structure and high-precision motion platform, the system supports efficient deployment for routine QA, machine performance verification, research, and training applications.
With positioning accuracy up to ±0.1 mm, the AS450 supports comprehensive dosimetric measurements, including Percentage Depth Dose (PDD), beam profiles, Tissue Phantom Ratio (TPR), and point-dose verification. Integration with the XBeam platform enables automated data acquisition, analysis, and reporting.
