Abstract
Description
La présente invention concerne un dispositif permettant l'autocont#Ie des mouvements respiratoires d'un sujet examiné en tomodensitomètrie. The present invention relates to a device allowing the self-control # Ie of the respiratory movements of a subject examined in computed tomography.
La situation dans l'espace des organes intra-thoraciques et intraabdominaux est fonction de l'état respiratoire d'mon sujet. La difficulté d'arrêter sa respiration de façon itérative à un seuil constant est préjudiciable à ltexamen de certains organes. The spatial situation of the intra-thoracic and intra-abdominal organs is a function of the respiratory state of my subject. The difficulty of stopping breathing iteratively at a constant threshold is detrimental to the examination of certain organs.
Traditionnellement on demande au sujet examiné de réaliser des apnées à un degré de remplissage pulmonaire qu'il estime constant. Cette manoeuvre est de réalisation délicate. Traditionally, the subject examined is asked to perform apneas at a degree of pulmonary filling that he considers constant. This maneuver is delicate.
Le dispositif selon l'invention permet de remédier à cet inconvénient. The device according to the invention overcomes this drawback.
Il comporte une tige courbe dont l'extrémité est maintenue en contact avec la cage thoracique ou l'abdomen du sujet grâce à son poids ou à un ressort. La tige est articulée sur un axe horizontal fixé sur un support placé entre les membres inférieurs du sujet, solidaire du plateau mobile de l'appareil tomodensitométrique. La tige est en contact avec un système de couplage permettant le repérage de la position dans 1 l'espace de la tige. Le circuit comporte aussi un systffime d'amplification et un systéme de mesure, visible par le sujet examiné.It has a curved rod, the end of which is kept in contact with the subject's rib cage or abdomen thanks to its weight or a spring. The rod is articulated on a horizontal axis fixed on a support placed between the lower limbs of the subject, secured to the movable plate of the CT scanner. The rod is in contact with a coupling system allowing the position in the space of the rod to be identified. The circuit also includes an amplification system and a measurement system, visible to the subject examined.
Dans la forme de réalisation préférentielle le dispositif comporte une résistance variable, un pont de " Wheat tone " avec une résistance modulable pour #lage-et et un ampéremétre. In the preferred embodiment the device comprises a variable resistance, a "Wheat tone" bridge with a modular resistance for # lage-et and an ammeter.
Selon les variantes le dispositif comporte un ou plusieurs des éléments suivants: une self variable, des transistors, des diodes tbermoluminescentes, un deuxième système de lecture pour l'examinateur, des miroirs pour faciliter la lecture. According to the variants, the device comprises one or more of the following elements: a variable choke, transistors, tbermoluminescent diodes, a second reading system for the examiner, mirrors to facilitate reading.
Le principe de fonctionnement est le suivant: la position de la tige, fonction de l'état respiratoire du sujet, est liée à un système de lecture visible par le sujet, permettant à celuici d'effectuer des apnées semblables. The operating principle is as follows: the position of the rod, a function of the subject's respiratory state, is linked to a reading system visible by the subject, allowing him to perform similar apneas.
Le dispositif selon l'invention est particulièrement destiné à la pratique de coupes tomodensitombtriques. The device according to the invention is particularly intended for the practice of tomodensitombometric cuts.
