3DVH®

You are here:

3DVH uses ArcCHECK QA measurements to estimate 3D dose to the patient geometry.

  • Perform 3D dose and DVH QA analysis on patient – not phantom – geometry
  • Supports coplanar and non-coplanar beams
  • Identify TPS and beam delivery errors

Phantom Evolution

3%/3mm criteria showing 99.2% passing rate, a good test of deliverability and machine performance.

Clinical Evaluation

Evaluating the same plan, 3DVH shows substantial target underdose, indicating that although the plan was properly delivered, the clinicial impact was below expectations.
