Knowledge-driven decision support for assessing dose distributions in radiation therapy of head and neck cancer

Abstract: The radiation therapy treatment planning decision support system presented here can assist clinicians in determining good dose constraints and assessing dose distributions by using knowledge gained from retrospective treatment plans.

“…Knowledge about patient’s day-to-day anatomical variation is furthermore valuable when (automating) selecting similar patients from a database of patients’ CT scans for, e.g., automating treatment planning or dose reconstruction [ 30 34 ], because this provides a lower bound on the achievable precision of selection.…”

“…The generation of atlases and matching of a query case to the best atlas were both based on two specially designed features, the PTV and SV concaveness angle and the percent distance (from SV) to the PTV Treatment parameters of the atlas case were transferred Deshpande et al 24 Direct Weighted sum of three difference values, the prescription dose differences, the OVH differences, and the difference of STS, which is a four-dimensional histogram encoding the radial distance, azimuth, and elevation of PTV in relation to the center of an OAR. The difference of histograms is calculated by the earth mover's distance…”

“…A knowledge-driven decision support system was proposed by [10], which quantifies the spatial relationships between the tumor and surrounding critical structures through features that account for distance, volume, overlap, location, shape and orientation. These features are used to identify database cases that are anatomically similar to a new patient, and help clinicians to estimate an acceptable dose distribution.…”
