A method to estimate the effect of deformable image registration uncertainties on daily dose mapping
Publikováno v:
Medical Physics. 39:573-580
Purpose: To develop a statistical sampling procedure for spatially-correlated uncertainties in deformable image registration and then use it to demonstrate their effect on daily dose mapping. Methods: Sequential daily CT studies are acquired to map a
