| 1. A method of scanning a patient using a medical imaging device, said method comprising:
acquiring data sets using the medical imaging device, at least one data set representative of the patient;
determining a defective cell in a row, n, of a detector of the medical imaging device using the acquired data sets;
determining a mode of operation of the medical imaging device, the mode of operation being at least one of a step-and-shoot
mode and a helical mode;
estimating an output of the defective cell using the determined mode of operation and at least one of a conjugate sample of
the defective cell, an adjusted conjugate sample of the defective cell, and an estimate of the output of the defective cell
using an output of a corresponding cell in an adjacent row;
reconstructing an image of the patient using the estimated output of the defective cell and the at least one data set representative
of the patient; and
outputting the reconstructed image.
