Method To Predict Three-Dimensional Radiotherapy Dose Distribution
This technology opens up a number of new possible applications in treatment planning optimization and plan evaluation. Some of these include: · Immediately after contour approval, radiation oncologists would have an expected treatment plan dose distribution to review, both guiding and accelerating the clinical decision making process for fractionation, target/organ prioritization, etc. · Treatment planners would have a powerful new diagnostic tool for understanding exactly where sub-optimal plans are failing, increasing efficiency and further eliminating human failure from the planning process. · New voxel-based optimization methods could be designed around these predictions, eliminating the need to convert DVH predictions to DVH-based optimization objectives and relative priorities. It is possible that this technology will herald yet another huge leap forward in clinical treatment planning, and in time the history of treatmentplanning advances could seen as: 2D àà 3D-conformal àà IMRT/RapidArc àà 1D-KBP àà 3D-KBP.
At UC San Diego, we have developed a major advance in knowledge-based treatment planning: full 3D dose distribution prediction. Similar to existing art1 our method relies on learning from a plurality of previously treated plans, but our method moves far beyond current technology to synthesize past experience into voxel-by-voxel predictions for expected dose distributions for new patients. Our current embodiment already meets or exceeds the accuracy of existing technology in DVH prediction, with the invaluable addition of identifying (a) precisely where the dose is expected to be deposited in the patient and (b) the degree of confidence in that voxel-by-voxel prediction. 1 See in particular US20120310615 (on which Dr. Kevin Moore was the lead inventor) and US20120014507.
