Abstract
A method of and apparatus for automatically calibrating a computed tomography ('CT') scanning system () is provided including providing () a calibration object () substantially centered on a translating table () for passing through the CT system (). The system () scans () the calibration object () and provides () a preliminary representation such as a display () of a sorted sinogram of the object (). From that preliminary representation, the system () determines intercept-related and/or slope-related values for at least a portion (or) of the preliminary representation and uses these values to calculate () one or more predetermined calibrations values.
