A two-dimensional (2D) graph is displayed of a parameter X equal to or proportional to (I) versus a parameter Y equal to or proportional to (II) where N is the number of fractions, D is a total radiation dose to be delivered by the fractionated radiation therapy, and dt is the fractional dose in fraction t. A constraint BED lines are displayed on the 2D graph depicting each BED constraint. A marker is displayed at a location on the 2D graph defined by a current fractionation and a current total dose. A new value for the current fractionation and/or the current total dose is received, and the marker is updated accordingly. Alternatively a second marker is displayed showing the new fractionation scheme along with its comparative advantages and disadvantages with respect to the current fractionation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fractionation selection tool in radiotherapy planning","description":"Fractionation optimization receives inputs including a radiation dose distribution to be delivered by fractionated radiation therapy, maximum and minimum number of fractions, and Biologically Effectiv","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11504547","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
