Abstract (en)
[origin: WO2022063802A1] The invention relates to a radiology assembly (10) comprising: - a tube (11) for generating a beam of x-rays (12) that is centred around a main emission direction (13), - a planar sensor (14) extending in a plane defined by a first direction (D1) and by a second direction (D2), which directions are substantially perpendicular to the main x-ray emission direction (13), the sensor being intended to receive the x-rays (12), the tube being characterised in that it comprises: - a first divided emitter (15) that is divided into two electromagnetic field-emitting portions; - a second divided emitter (16) that is divided into two electromagnetic field-emitting portions; - a planar electromagnetic field emitter (24), - electromagnetic field sensors (29, 30, 31, 32) that are securely fastened to the planar sensor (14), - a processing means (17) that is intended to determine an angle of alignment between the main emission direction (13) and a normal (N1) of the planar sensor (14) and to determine first and second centering errors, and - a means (171) for correcting the angle of alignment by applying a first corrective movement to the generating tube (11) and first and second centering errors by applying the first corrective movement and/or a second corrective movement to the generating tube (11).
