Patent ID: 6980681

Claim:
A method for imaging an object with a computed tomographic (CT) imaging system, comprising the steps of: helically scanning the object with a multi-slice CT imaging system having a plurality of detector rows to acquire attenuation measurements of the object, the measurements including more than two conjugate samples, wherein a difference between a view angle of one of the more than two conjugate samples and a view angle of any one of the remaining conjugate samples of the more than two conjugate samples is n π, wherein n is an integer greater than zero; estimating at least one projection along a curved plane of reconstruction of the object using the attenuation measurements of the object, including the more than two conjugate samples; applying different weighting functions within each detector row dependent upon a division of conjugate regions for each detector row and dependent upon view angles in a curved plane for corresponding detector rows; and filtering and backprojecting the attenuation measurements of the object, including the more than two conjugate samples, to reconstruct at least one image slice of the object.
