A method and a system for correcting and reconstruing a plurality of projection images based on detected patient motion. The method includes obtaining a plurality of projection images generated by a scanner. Each of the plurality of projection images includes at least three markers. Each of the at least three markers has a measured three-dimensional position and measured positions on a detector panel of the scanner in a first dimension and a second dimension. The method further includes determining a position error vector for each of the plurality of projection images based on the at least three markers in each of the plurality of projection images, the position error vector defining patient motion in the projection image. The method finally includes combining each position error vector for each of the plurality of projection images with geometric parameters associated with the scanner to derive a projection matrix for each of the plurality of projection images, and generating reconstructed images corrected for patient motion from the plurality of projection images and the projection matrix for each of the plurality of projection images.
