Abstract (EN): Methods based on bi-planar radiography enable performing 3D reconstructions of bone structures (e.g. spine) with much less radiation than CT. These methods require a calibration procedure that must be executed for every examination to capture the geometrical parameters of the imaging system. In most of the published work, calibration is performed using non-standard equipments of large dimensions that enclose the patient and introduce undesirable objects into radiographs. In this paper we propose a method for geometrical calibration of bi-planar radiography that aims at minimising the impact of calibration objects on the content of radiographs, while requiring minimal adaptations to standard x-ray imaging systems.
