ABSTRACT:
A method for aligning a patient for radiation treatment based on an earlier tomographic scan of the patient uses projection images used to reconstruct a tomographic image rather than reconstructed images and compares the projection images directly to projection images taken at the time of the radiation therapy to determine a series of offsets of the patient which may be used to characterize and correct for motion of the patient between the initial tomographic scan, used for treatment planning, and one or a series of subsequent radiation treatment sessions.
