<P>PROBLEM TO BE SOLVED: To determine an error in aligning a patient with a radiation beam in a method. <P>SOLUTION: A planning volume V is acquired during treatment planning, and a treatment volume I is acquired during treatment. For each point r in the planning volume and treatment volume to be aligned by a coordinate transformation T, a weighted error WE is minimized using an objective function F(r, T) applied to the planning volume and the treatment volume weighted by a weighting function W(r) as the formula: WE(T)=Σ<SB POS="POST">r</SB>W(r)F(r, T) (wherein W(r) is a function of a target weight W<SB POS="POST">T</SB>, a tissue at risk weight W<SB POS="POST">R</SB>, and a delivered dose weight W<SB POS="POST">D</SB>). <P>COPYRIGHT: (C)2012,JPO&INPIT |
