Secondary Monitor Unit Calculation, MU2net is a system designed to calculate Monitor Units (MU) independently from the TPS.
It works from original DICOM files or the manual entry and checks the validity of TPS computed MU.
It gives the possibility to intercept automatically the DICOM files sent to the Record&Verify system and to trigger an alerte in case of discrepancy. It supports photon and electron beams, blocks and wedges, static MLC, IMRT and VMAT/RapidArc® techniques.
Fast and accurate MU calculation
Statistical analysis tool
MU2net was simple to set up and for a daily routine, its user interface is intuitive. You just need to send the plan via DICOM from the treatment planning system to MU2net to get the secondary calculation of the monitor units based on a totally independent model, whatever the treatment technique is.
To adjust the calculation, MU2net offers the possibility of assigning to the structures a density different from 1. It allows taking into account the lungs, for example.
We have used MU2net for more than 200 VMAT cases. Most of the time when the calculation point is in a low gradient dose area, we got less than 3 % deviation.
