Conclusion:

The dose and volume parameters estimation by contouring on CBCT, though accurate, is time consuming. The limitation of PerFRACTION™ is that a deformable registration-based system must be employed before it can be used for dose estimation in adaptive planning. It was observed that the Velocity™ system, using dose deformation was more effective in accurately estimating the dose/volume parameters using weekly CBCT as compared to EPID-based in-vivo system.
