Patent ID: 8043003

Claim:
A method for determining an imaging rule at a position of imaging components of a radiographic imaging system, comprising: defining a first position of the imaging components as an actual imaging position; positioning a calibration phantom with a structural element into the radiographic imaging system at which the calibration phantom is at least partially imaged in X-ray images taken from the actual imaging position; defining a calibration imaging position of the imaging components at which the calibration phantom is completely imaged; taking X-ray images of the calibration phantom at the calibration imaging position and at the actual imaging position; determining an imaging rule at the calibration imaging position; detecting a movement process from the calibration imaging position to a movement parameter in the actual imaging position; converting the imaging rule at the calibration imaging position to the imaging rule at the actual imaging position based on the movement parameter; defining a complementary position of the imaging components for the actual imaging position such that the X-ray image of the calibration phantom at the calibration imaging position comprises both the structure element that is imaged and not imaged in the X-ray image taken at the actual imaging position; taking an X-ray image at the complementary position; registering the X-ray image taken at the complementary position with the X-ray image taken actual imaging position; and assigning a structure in the registered X-ray image to the structural element of the calibration phantom.
