Abstract
A reconstruction system reconstructs projection data generated by a detector array of an imaging system having at least one truncated row of detector modules. The reconstruction system includes a projection data generator that augments the projection data with projection data created for the at least one truncated row of detector modules. The reconstruction system further includes a convolver that convolves the augmented projection data. The reconstruction system further includes a back-projector back-projects the augmented projection data and generates volumetric image data indicative thereof.
