Radiation assembly and method of aligning the assembly

Abstract

The invention relates to a radiation assembly (10) and to a method for aligning the assembly, comprising: an x-ray tube (11) for generating a beam of x-rays (12) centered in a main emission direction (13); and A flat sensor (14) intended to receive x-rays (12), approximately perpendicular to the main emission direction (13). According to the invention, the radiating assembly (10) comprises a first split emitter (15, 16) divided into two electromagnetic field emitting parts, said emitters being placed along a main direction substantially perpendicular to the main emission direction (13). The first electromagnetic field is emitted in the direction, each of the two emitting parts of the split emitter (15, 16) is positioned on either side of the x-ray (12) beam; the electromagnetic field sensor (29, 30, 31, 32), It is fixedly fastened to a flat sensor (14) and is capable of detecting an electromagnetic field emitted by an emitter (15, 16) and is capable of generating a first electrical signal from the detected electromagnetic field; and means for processing the first electrical signal (17 ), which is used to determine the relative position of the flat sensor (14) with respect to the x-ray tube (11).

Description

technical field [0001] The present invention relates to a radiation assembly, and more particularly to the alignment of two elements of the radiation assembly, the x-ray tube, relative to a flat sensor. The invention also relates to a method of aligning the radiation assembly. The present invention relates to the field of radiology (eg medical or veterinary radiology). [0002] In this patent application, the invention is presented in the context of its application to a radiation assembly. However, the invention can be applied in other fields where the correct positioning of two elements relative to each other is required. Background technique [0003] The radiology assembly consists of two elements: an x-ray tube and a flat sensor for radiographic images. This component is designed primarily to generate radiographic images of patients in a hospital environment. The patient desired for radiography is positioned between the x-ray tube and the flat sensor. These two eleme...

Problems solved by technology

This alignment is unsuitable since, in the case of radiology applications, the patient may locally attenuate the electromagnetic wave and thus corrupt the measurement
