1. A system comprising:
- at least one programmable processor; and
a non-transient machine-readable medium storing instructions which, when executed by the at least one programmable processor, cause the at least one programmable processor to perform operations comprising;
(a) receive a subset of radiation planning data for a given patient selected from a set of;
anatomy volume contours and target volume prescriptions;
(b) generate a fictitious treatment dose matrix from the subset of radiation planning data with a modeling process wherein the subset and the modeling process are selected so that the fictitious treatment dose matrix provides a quality of dose placement beyond that achievable with a physically realizable radiation therapy machine;
(c) receive radiation planning information selected from the group consisting of radiation plan goals for the given patient and a clinical radiation therapy plan for the given patient;
(d) evaluate the radiation planning information against the fictitious treatment dose matrix; and
(e) output the evaluation.

Abstract
A system for evaluating radiation treatment planning generates a fictitious treatment dose matrix with a quality of dose placement beyond that achievable with physically realizable radiation therapy machines. Such a fictitious treatment dose matrix provides an objective measure that is readily tailored to different clinical situations, and although unattainable, thereby provides a benchmark allowing evaluation of radiation plan goals and the radiation plans between different multiple clinical situations and individuals.

17. A system comprising:
-
at least one programmable processor; and a non-transient machine-readable medium storing instructions which, when executed by the at least one programmable processor, cause the at least one programmable processor to perform operations comprising; (a) receive a subset of radiation planning data for a given patient selected from a set of;
