PURPOSE To present a generic geometric calibration method for tomographic imaging systems with flat-panel detectors in a very detailed manner, in the aim to provide a useful tool to the public domain. METHODS The method is based on a projection matrix which represents a mapping from 3D object coordinate system to 2D projection image plane. The projection matrix can be determined experimentally through the imaging of a phantom of known marker geometry. Accurate implementation was accomplished… CONTINUE READING
