Treat Patients Sooner with Quality and Confidence

Commissioning Timeline

Prior to arrival, Landauer Medical Physics will secure information specific to your institution that ensures the system is commissioned properly to deliver the desired doses. Following commissioning, we provide a suggested set of tests your physicist can use to verify data and beam model prior to treating patients. This truly independent verification can be completed in a single day.

A key benefit of having Landauer Medical Physics handle your commissioning is that our physics team is free from clinical duty interruptions that occur when site physicists commission their own equipment.
