Abstract
A method for fast inverse planning of IMRT treatment plans is disclosed. The method relies on a computationally efficient algorithm for evaluating the gradient of a general class of objective functions, and also on the efficient optimization that is realized due to the directional conjugacy of the objective functions. Several types of clinically relevant objective functions that belong to this class are described. The computational evaluation relies on operations that are commonly used for signal- and image-processing, and so can benefit from a number of well-known acceleration techniques.
