ABSTRACT:
A method for reconstructing tilted cone beam data acquired using a CT apparatus. The CT apparatus has a gantry and a table. The gantry has an x-ray source and a detector array with columns and rows. The gantry is tilted at a gantry tilt angle with respect to the table and a plurality of projection data is acquired using the CT apparatus. Fan-parallel rebinning is performed on a row by row basis to form a plurality of reconstructed pixels. The coordinate locations of the plurality of reconstructed pixels are adjusted based on the gantry tilt angle and used to form a reconstructed image.
