Maximum curvature for radiotherapy calculated by value decomposition analysis
October 25th, 2005
The point of maximum curvature for radiotherapy could be calculated by value decomposition analysis. "We attempt to select an optimal value of regularization parameter in the optimization problems for intensity-modulated radiotherapy which are solved using a variational regularization technique. We apply to inverse treatment planning the L-curve method which was developed to determine the regularization parameter in the discrete ill-posed problems," researchers in the United States reported. "The L-curve method is based on finding the regularization parameter which minimizes the residual norm which is a measure of accuracy of fit and the solution...
