Abstract:
Relative movement about an axis of rotation is caused as between an energy source/detector array with respect to an object (where the object can comprise either an object to be projected to facilitate a study of the object or a calibration object to be projected as part of calibrating usage of the energy source/detector array). The energy source/detector array are used during this relative movement to scan the object and to obtain corresponding object project data. That object projection data is then used 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 aforementioned relative movement to scan the object.
