Description
-1- La présente invention concerne un boitier diviseur, caractérisé en ce qu'il permet de minimiser l'exposition d'un patient aux rayons X lors d'examens d'imageries médicales dits « stitching » en divisant le champ ouvert des rayons x en trois fenêtres distinctes, ceci afin de répondre aux normes de radio protection humaine.The present invention relates to a divider box, characterized in that it makes it possible to minimize the exposure of a patient to X-rays during examinations of so-called "stitching" medical imageries by dividing the open field of x-rays. in three separate windows, this in order to meet human protection radio standards.
Les examens dits « stitching » sont spécifiques au rachis et membres inférieurs, avec les anciennes technologies ont utilisait des films de radiologie 30 x 120 cm, la technique consistait à ouvrir au maximum le champ des rayons x afin de couvrir toute la surface de la colonne vertébrale, puis ensuite de faire un cliché de celle-ci. Aujourd'hui, avec la nouvelle génération d'imagerie médicale on utilise des capteurs plans numériques d'une dimension de 43 x 43 cm, nous sommes donc obligé de faire l'examen en prenant 3 radiographies qui sont ensuite reconstruites à l'aide d'un logiciel spécifique. Selon les normes de radio protection humaine, nous n'avons pas le droit de surexposer un patient aux rayons x, donc, nous ne pouvons pas faire trois clichés pleins corps. Pour ce faire, les radiologues sont obligés de limiter l'ouverture des rayons x à une fenêtre de 50 x 50 cm, puis de faire trois clichés en déplaçant entre chaque clichés le tube à rayons x, le problème est que le patient ne peux pas rester sans bouger durant une longue période et que cette façon de faire n'est pas précise et très longue ! Selon une première caractéristique, la présente invention est caractérisée en ce que le boitier diviseur permet de scinder la surface de radiographie à prendre en trois sans avoir à toucher le tube à rayons x. Selon une deuxième caractéristique, le boiter diviseur est synchronisé avec un Potter (machine verticale ou se trouve le capteur plan), à chaque position de celui-ci, haute, milieu et basse, le boitier diviseur ouvrira la fenêtre correspondante par l'intermédiaire de deux volets plombés, eux-mêmes pilotés par un signal infra-rouge reçu du Potter.The so-called "stitching" examinations are specific to the spine and lower limbs, with the old technologies using 30 x 120 cm radiology films, the technique was to open up the x-ray field as much as possible in order to cover the entire surface of the column vertebral, and then make a snapshot of it. Today, with the new generation of medical imaging we use digital planar sensors with a size of 43 x 43 cm, so we are obliged to make the examination by taking 3 x-rays which are then reconstructed using 'a specific software. According to human protection radio standards, we do not have the right to overexpose an x-ray patient, so we can not do three full body shots. To do this, radiologists are obliged to limit the opening of x-rays to a window of 50 x 50 cm, then to make three snapshots by moving between each shot the x-ray tube, the problem is that the patient can not to remain motionless for a long time and that this way of doing things is not precise and very long! According to a first characteristic, the present invention is characterized in that the divider box makes it possible to split the radiography surface to be taken in three without having to touch the x-ray tube. According to a second characteristic, the divider box is synchronized with a Potter (vertical machine where the plane sensor is located), at each position of it, high, middle and low, the divider box will open the corresponding window via two sealed shutters, themselves driven by an infra-red signal received from the Potter.
