Abstract:
1. A method comprising: providing an energy source and a corresponding detector array comprising multiple detector channels; providing an object; causing relative movement of at least one of the energy source and the corresponding detector array with respect to the object about an axis of rotation; using the energy source and the corresponding detector array while causing the relative movement to scan the object to obtain object projection data; using the object projection data for a plurality of the multiple detector channels to determine a parameter as corresponds to at least one scanning geometry characteristic as corresponds to using the energy source and the corresponding detector array while causing the relative movement to scan the object, such that the parameter is determined even when the object comprises an object other than a calibration object and is being projected to facilitate a study of the object other than solely as part of calibrating usage of the energy source and the corresponding detector array, wherein the scanning geometry characteristics comprises a value that corresponds to a sample pitch.
