1. A method for correcting truncated projection data in computed tomography images of a patient recorded by an imaging recording device, comprising: acquiring truncated projection data of a patient during rotation of an imaging recording device until an angular range of projection data has been captured by: (a) recording a truncated projection image having at least one truncated portion of the patient; (b) recording the at least one truncated portions of the patient for the truncated projection; (c) assembling the truncated projection image and the at least one truncated portions into a complete projection; (d) incrementing an angle of rotation in the angular range; estimating intermediate values of the truncated projection data based on a geometry model of the patient from the complete projection; and reconstructing the truncated projection data based on the acquired truncated projection data and the estimated intermediate values of the truncated projection data.
