Abstract
A system and method of calibrating an imaging system, in which intrinsic parameters relating to the various types of image which can be taken are calibrated in predetermined angular positions of an emitter of radiation, and of a receiver of the radiation. The intrinsic parameters are estimated using a two-dimensional phantom in order to establish a distortion field for a particular angulation, the distortion field for any angulation being calculated by polynomial interpolation of the distortion fields, each established for a control point, a control point being defined by a particular angulation for each axis of rotation of the imaging system, having to be subject to calibration.
