ABSTRACT:
A method of correcting for motion of a patient during a CT scan includes observing positions of radio-opaque markers in a series of two dimensional x-ray projections taken by a scanner. The markers are positioned on a patient in a fixed and rigid relationship, a CT scan is performed to obtain a three dimensional CT image, and an actual projected position of each of the markers in each two dimensional projection is determined. A motion data set is obtained based on the actual projected positions of the plurality of the markers. A final three dimensional CT image is reconstructed employing the motion data set.
