How to Apply 3D3 Prediction? A Novel Mathematical Model to Generate Pareto Optimal Clinical Applicable IMRT Treatment Plan On the Foundation of Dose Prediction and Prescription

Abstract: In this paper knowledge based planning has been revolutionized via a novel mathematical model which converts three dimensional dose distribution (3D3) prediction to a clinical utilizable IMRT treatment plan. Presented model has benefited from both prescribed dose as well as predicted dose and its objective function includes both quadratic and linear phrases, so it was called QuadLin model. The model has been run on the data of 30 patients with head and neck cancer randomly selected from the Open KBP dataset. For each patient, there are 19 sets of dose prediction data in this database. Therefore, a total of 570 problems have been solved in the CVX framework and the results have been evaluated by two plan quality approaches: 1- DVH points differences, and 2- satisfied clinical criteria. The results of the current study indicate a strong significant improvement in clinical indicators compared to the reference plan of the dataset, 3D3 predictions, as well as the results of previous researches. Accordingly, on average for 570 problems and total ROIs, clinical indicators have improved by more than 21% and 15% compared to the predicted dose and previous research, respectively.
