Conclusion: MVCT/MV CBCT

 Geometric accuracy:

 MV CT: Mechanical rigidity of the system minimizes geometrical uncertainties.  MV CBCT: Geometrical uncertainties are quantified and included in projection matrices and filtered back projection algorithm.  Image quality: Adequate for all systems MV CT and CBCT ready to be used for dose calculations 

  Patient dose:

Depends on what you ask for.
