However, when 3D conformal radiotherapy (3D CRT) is required, the techniques that must be used to produce an acceptable plan can prove onerous and time-consuming due to the very nature of the unflattened beam.
While their department has proven successful in securing authorization to use the more complex planning and delivery techniques, there remains a significant portion of their patient population (~14%) that require 3D conformal planning techniques.
Planning times being what they are, the dosimetrist spends approximately 63% of the total treatment planning time (adjusting constraints, coverages, balancing fluences, etc.) on 14% of the center’s patient population.
“While it’s tempting to hawk only the cost-savings aspect of EZFluence, perhaps the more important point is that our dosimetrist can now devote more time to other, more demanding and complex treatment planning techniques for difficult treatments. The end result is fewer touch points in the creation of our plans and the enhanced ability to handle ‘overflow’ situations.”
– Jennifer Fisher, NEOK physicist
With EZFluence, the dosimetrist now spends an average of 20-30 minutes on planning a patient requiring 3D CRT in contrast to the 8-10 hours previously spent manually generating a single plan.
NEOK has found EZFluence useful not only for automating 3D-CRT planning for the 14% of their patients that require it, but also to expedite IMRT/VMAT justification plans for billing purposes. Due to insurance scrutiny of IMRT for breast, skin, and lung, their department now uses EZFluence for approximately 50% of their planning needs.
By incorporating EZFluence into its workflow, the department extended speed and efficiency to the planning side of operations, easing dosimetry constraints and reducing the burden required to produce top-quality treatment plans.
