Abstract
A computer-implemented method for optimizing a radiation treatment plan for a radiotherapy machine providing independently controlled radiation along a plurality of rays j directed toward a patient and configured to account for the effects of patient motion. The method includes generating a probability distribution function quantitatively expressing patient motion, identifying a prescribed total dose Dat the voxels i in a treatment area, assigning a fluence value wfor each ray j based on an iterative function, calculating an actual total dose Dproduced each voxel i within the assigned fluence values and calculating an expectation value of the dose per energy fluence,dbased on the actual total dose Dand the probability distribution function.
