Abstract
A method of controlling radiation dosage of an X-Ray CT system includes applying radiation to a patient along a z-axis in an x-y plane at angles during rotations around the z-axis. The method also includes acquiring projections of the patient to reconstruct a 3D image of the patient's anatomy and controlling a dosage of the radiation by causing a same dosage of the radiation to be applied in the x-y plane to a posterior of the patient and to an anterior of the patient at a first portion along the length of the z-axis and causing a varied dosage of the radiation to be applied in the x-y plane at a second portion along the length of the z-axis. The varied dosage includes a first dosage applied to the posterior and a second dosage applied to the anterior that is less than the first dosage.
