Abstract
A method for calibrating a device D includes at least one radiation source and a detector, the radiation source and the detector being installed on at least one moving support, comprising at least the following elements: at least one first sensor positioned close to the radiation source and at least one second sensor positioned close to the detector, the two first and second sensors being configured to estimate through calculation a position Ps of the source and a position Pd of the detector, and a sensor for sensing the angular position of the moving support, a synchronization module configured to synchronously trigger the measurements of the sensors, a module for pre-processing the measurements of the sensors, the processing module comprising an input receiving an operating model M of the device and a data merging algorithm taking into account at least the two measurements of the sensors and the model M in order to estimate an accurate position value for the source Ps and for the detector Pd.
