摘要： A radiology assembly and a method for aligning such an assembly, comprising comprises: an x-ray tube for generating a beam of x-rays that is centered on a main emission direction; and substantially perpendicular to the main emission direction, a planar sensor to receive the x-rays. The radiology assembly comprises: a first divided emitter that is divided into two electromagnetic-field-emitting portions, the emitter being placed so as to emit a first electromagnetic field in a main direction that is substantially perpendicular to the main emission direction, each of the two emitting portions of the divided emitter being positioned on one side of the beam of x-rays; electromagnetic-field sensors that are securely fastened to the planar sensor and that are able to detect the electromagnetic fields emitted by the emitters and to generate a first electrical signal depending on the detected electromagnetic field; and a means for processing the first electrical signal to determine the relative position of the planar sensor with respect to the x-ray tube.

摘要： A radiology assembly includes an x-ray tube for generating a beam of x-rays that is centered around a main emission direction, a planar sensor extending in a plane defined by a first direction and by a second direction, which directions are substantially perpendicular to the main x-ray emission direction, the sensor being intended to receive the x-rays, comprising a first divided emitter that is divided into two electromagnetic-field-emitting portions; a second divided emitter that is divided into two electromagnetic-field-emitting portions; a so-called planar electromagnetic-field emitter, electromagnetic-field sensors that are securely fastened to the planar sensor, a processing means intended to determine an angle of alignment between the main emission direction and a normal of the planar sensor, to determine a first centering error and a second centering error, a correcting means for correcting the angle of alignment by applying a first corrective movement to the x-ray tube and first and second centering errors by applying the first corrective movement and/or a second corrective movement to the x-ray tube.
