Sophistication that makes QA simple

With a choice of software options you can expand the potential of your Delta 4PT with the ability to view 3D results in the patient anatomy, set pass/fail criteria for specific structures, evaluate in 4D where any deviation in delivery occurs. With the Machine QA option you can also increase your efficiency and run routine QA analysis of the beam constancy, flatness, and MLC position.
