One embodiment of the present invention is a method for imaging an object with
a computed tomographic (CT) imaging system that includes steps of helically scanning
the object with a multi-slice CT imaging system to acquire attenuation measurements
of the object, the measurements including more than two conjugate samples for estimation
of a projection at a plane of reconstruction of the object; 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. An improved sampling
pattern and better use of the attenuation samples obtained during a scan is thus provided.
