PROCEDE D'ANELIORATION DE LA QUALITE DES CLICHES
RADIOLOGIQUES ET DISPOSITIF PERMETTANT
LA MISE EN OEUVRE DU PROCEDE
La présente invention concerne un procédé d'amélioration de la qualité des clichés radiologiques et le dispositif associé.PROCESS FOR IMPROVING THE QUALITY OF PHOTOGRAPHS
RADIOLOGICAL DEVICES AND PERMITTING DEVICE
THE IMPLEMENTATION OF THE PROCESS
The present invention relates to a method for improving the quality of radiological images and the associated device.
Dans les techniques actuelles de radiologie, les clichés obtenus lors de la prise de clichés de partie du corps à épaisseur variable présentent des zones sur ou sous exposées. Ces phénomènes se présentent notamment lors des radiographies d'un doigt sur sa périphérie, d'une épaule ou de la colonne vertébrale, en particulier dans la zone lombaire ou cervicale, ou encore lors des mammographies sur les zones cutanées ou sous-cutanées. In the current radiology techniques, the radiographs obtained when taking radiographs of the body part with variable thickness have over or under exposed areas. These phenomena occur in particular during x-rays of a finger on its periphery, of a shoulder or of the spine, in particular in the lumbar or cervical area, or also during mammograms on the skin or subcutaneous areas.
On a essayé de pallier ces inconvénients par différentes techniques, utilisant, par exemple, des cônes de filtrage ou des grilles, pour diminuer les diffusions de rayonnement. Malgré ces améliorations, les régions de faible épaisseur sont encore sur-exposées. We have tried to overcome these drawbacks by different techniques, using, for example, filter cones or grids, to reduce radiation scattering. Despite these improvements, the thin regions are still over-exposed.
Un premier but de l'invention est donc de proposer un procédé d'amélioration de la qualité des clichés radiologiques. A first object of the invention is therefore to propose a method for improving the quality of radiological images.
Ce but est atteint par le procédé de l'invention qui consiste à interposer sur le trajet du rayonnement entre la cible et le film sensible aux rayons X ou entre le tube et la cible, une poche en matériau déformable, remplie partiellement sous vide par un fluide ou un gel. This object is achieved by the method of the invention which consists in interposing on the radiation path between the target and the film sensitive to X-rays or between the tube and the target, a bag of deformable material, partially filled under vacuum by a fluid or gel.
Selon une autre particularité, le procédé consiste à exercer une pression sur la cible et la poche pour déformer cette dernière. According to another particular feature, the method consists in exerting pressure on the target and the pocket to deform the latter.
Selon une autre particularité, la poche est mobile et placée sur le plateau porte-film d'un appareil de radiographie ou sous la plaque de compression. According to another particularity, the pocket is mobile and placed on the film-holding plate of an X-ray device or under the compression plate.
Selon une autre particularité, la poche est solidaire d'une face du plateau porte-film de l'appareil de radiographie ou d'une face de la plaque de compression. According to another particularity, the pocket is integral with one face of the film-holding plate of the radiography device or of one face of the compression plate.
Selon une autre particularité, le fluide est de l'eau. In another feature, the fluid is water.
Selon une autre particularité, le volume de fluide ou de gel remplissant partiellement la poche est compris entre le quart et la moitié du volume maximum admissible. According to another particular feature, the volume of fluid or gel partially filling the bag is between a quarter and a half of the maximum admissible volume.
Selon un autre particularité, le volume de fluide ou de gel remplissant partiellement la poche est de préférence compris entre un quart et un tiers du volume maximum admissible. According to another particular feature, the volume of fluid or gel partially filling the bag is preferably between a quarter and a third of the maximum admissible volume.
Selon une autre particularité, le fluide ou le gel remplissant la poche a une viscosité comprise entre 10.000 et 100.000 centipoises. According to another particular feature, the fluid or gel filling the bag has a viscosity of between 10,000 and 100,000 centipoises.
Selon une autre particularité, la poche est fixée à ses extrémités. According to another particularity, the pocket is fixed at its ends.
Un autre but de l'invention est de proposer un dispositif permettant d'améliorer la qualité des clichés radiologiques. Another object of the invention is to propose a device making it possible to improve the quality of the radiological images.
Ce but est atteint par le fait que le dispositif comporte au moins une poche en matériau déformable remplie partiellement sous vide par un gel ou un fluide et interposée sur le trajet du rayonnement généré par une source de rayons X entre la cible et le film sensible aux rayons X ou entre le tube et la cible. This object is achieved by the fact that the device comprises at least one pocket of deformable material partially filled under vacuum with a gel or a fluid and interposed on the path of the radiation generated by an X-ray source between the target and the film sensitive to X-rays or between the tube and the target.
Selon une autre particularité, la poche mobile est placée sur le plateau porte-film de l'appareil de radiographie ou sous la plaque de compression. According to another particularity, the mobile pocket is placed on the film-holding plate of the radiography device or under the compression plate.
Selon une autre particularité, la poche est solidaire d'une face du plateau porte-film. According to another particular feature, the pocket is integral with one face of the film-holding tray.
Selon une autre particularité, le fluide est de l'eau. In another feature, the fluid is water.
Selon une autre particularité, le volume de fluide remplissant partiellement la poche est compris entre le quart et la moitié du volume maximum admissible. According to another particular feature, the volume of fluid partially filling the pocket is between a quarter and a half of the maximum admissible volume.
Selon une autre particularité, une deuxième poche est interposée entre la source de rayonnement et la cible, ladite deuxième poche étant associée avec des moyens permettant l'application de cette deuxième poche avec une pression donnée sur la cible. According to another particularity, a second pocket is interposed between the radiation source and the target, said second pocket being associated with means allowing the application of this second pocket with a given pressure on the target.
Selon une autre particularité, cette deuxième poche est remplie partiellement d'air. In another feature, this second pocket is partially filled with air.

La figure 1 représente, dans une application à la mammographie, une vue du dispositif permettant la mise en oeuvre du procédé. Ce dispositif est constitué d'une source, non représentée, générant un rayonnement X, ce rayonnement étant orienté substantiellement perpendiculairement aux plaques (4, 2) de cette figure. Sur le trajet, ce rayonnement rencontre successivement une plaque transparente (4) montée au bout d'une fourchette (40) qui permet d'exercer une pression sur la cible (1) constituée par le membre, en l'occurrence ici un sein que l'on souhaite radiographier. En dessous de la cible est placée une poche (3a) qui repose sur une plaque support (2) au dessous de laquelle est placé le film sensible aux rayons X. FIG. 1 represents, in an application to mammography, a view of the device allowing the implementation of the method. This device consists of a source, not shown, generating X-ray radiation, this radiation being oriented substantially perpendicular to the plates (4, 2) of this figure. On the way, this radiation successively meets a transparent plate (4) mounted at the end of a fork (40) which allows to exert pressure on the target (1) formed by the member, in this case a breast that we want to x-ray. Below the target is placed a pocket (3a) which rests on a support plate (2) below which the X-ray sensitive film is placed.
La poche (3) est constituée, comme représenté aux figures 2 à 4, par une enveloppe fermée, elle-même constituée par des surfaces supérieure (30) et inférieure (31B, 31A) formant un volume fermé accessible de l'extérieur par deux appendices (33, 34) en forme de tube, situés, par exemple, dans le prolongement de la partie longitudinale de la poche (3). Ces appendices comportent des robinets (35, 36) permettant, pour le premier (35), d'introduire le fluide ou gel de remplissage de la poche, et pour le second (36), de faire le vide. The pocket (3) is constituted, as shown in FIGS. 2 to 4, by a closed envelope, itself constituted by upper (30) and lower (31B, 31A) surfaces forming a closed volume accessible from the outside by two appendages (33, 34) in the form of a tube, situated, for example, in the extension of the longitudinal part of the pocket (3). These appendages comprise taps (35, 36) allowing, for the first (35), to introduce the fluid or gel for filling the bag, and for the second (36), to create a vacuum.
La figure 2 présente une forme en demi-lune ou rectangulaire de la poche, plus adaptée, notamment dans les applications de mammographie. FIG. 2 shows a half-moon or rectangular shape of the pocket, more suitable, in particular in mammography applications.
La figure 3 permet de voir la surface (30) déformée par le corps ou la partie du corps qui est pressée sur la poche, comme par exemple dans le cas d'une mammographie représentée à la figure 1. La partie du corps appuyant sur la face supérieure de la poche, provoque une déformation de celle-ci et un reflux du fluide ou du gel dans les zones où le membre présente une épaisseur moindre. Pour permettre un bon fonctionnement du dispositif, la poche doit être remplie partiellement et le volume de fluide ou de gel doit être compris entre le quart et la moitié du volume maximum de la poche, de préférence entre le quart et le tiers du volume maximal. FIG. 3 shows the surface (30) deformed by the body or the part of the body which is pressed on the pocket, as for example in the case of a mammography shown in FIG. 1. The part of the body pressing on the upper face of the pocket, causes its deformation and a reflux of the fluid or gel in the areas where the member has a reduced thickness. To allow the device to function properly, the bag must be partially filled and the volume of fluid or gel must be between a quarter and a half of the maximum volume of the bag, preferably between a quarter and a third of the maximum volume.
La surface inférieure de la poche, par exemple (3 lob) représentée sur la figure 3 peut, dans certaines variantes, avoir une épaisseur supérieure de façon à assurer une certaine rigidité à cette surface, surtout lorsque la poche est mobile et simplement posée sur la face du plateau (2) orientée vers la source de rayonnement alors que l'autre face supporte le film sensible aux rayons X.The lower surface of the pocket, for example (3 lob) shown in Figure 3 may, in some variants, have a greater thickness so as to ensure a certain rigidity to this surface, especially when the pocket is mobile and simply placed on the face of the plate (2) oriented towards the radiation source while the other face supports the X-ray sensitive film.
Dans une autre variante représentée à la figure 4 les extrémités de la poche proches des embouts (33, 34) seront maintenues par des ergots (20) rendus solidaires de la plaque (2) support de film par tous moyens connus de l'homme de métier. In another variant shown in FIG. 4, the ends of the pocket close to the end pieces (33, 34) will be held by lugs (20) made integral with the film support plate (2) by any means known to those skilled in the art. job.
Une troisième possibilité consiste à rendre la face inférieure (31a) solidaire de la face supérieure de la plaque (2) par tous moyens tels que collage ou soudage. Dans ce cas là la plaque (2) peut elle-même constituer une partie de l'enveloppe et seulement une feuille sera soudée à la plaque pour constituer la partie supérieure de l'enveloppe (30). A third possibility consists in making the lower face (31a) integral with the upper face of the plate (2) by any means such as bonding or welding. In this case the plate (2) can itself constitute a part of the envelope and only one sheet will be welded to the plate to constitute the upper part of the envelope (30).
Lorsque la poche devra être utilisée dans des applications nécessitant une position verticale, telle que celle représentée à la figure 5, une poche du type (3b) sera utilisée de préférence, cette poche étant remplie d'un fluide ou d'un gel ayant une viscosité importante, par exemple comprise entre 10.000 et 100.000 centipoises et de préférence de l'ordre de 50000 centipoises. Le gel peut, par exemple, être un gel echographique commercialisé par Ondes et Rayons ROCHE
GARS S.A. sous la dénomination SONECHO. L'enveloppe de la poche pourra être réalisée en tout matériau déformable et considéré comme transparent aux rayons tel que par exemple un élastomère, du caoutchouc, etc...When the bag must be used in applications requiring a vertical position, such as that shown in FIG. 5, a bag of the type (3b) will preferably be used, this bag being filled with a fluid or a gel having a high viscosity, for example between 10,000 and 100,000 centipoise and preferably of the order of 50,000 centipoise. The gel may, for example, be an ultrasound gel marketed by Ondes et Rayons ROCHE
GARS SA under the name SONECHO. The envelope of the pocket may be made of any deformable material and considered to be transparent to the rays such as for example an elastomer, rubber, etc.
Enfin, dans une dernière variante, une deuxième poche peut être rendue solidaire de la palette transparente (4). Cette deuxième poche est de préférence remplie d'air pour ne pas affecter le passage du rayonnement, cette poche a pour but d'améliorer le confort et la compression appliquée sur le membre. Ceci est particulièrement important dans le cas d'une mammographie pour le confort de la patiente et la répartition égale de la pression sur le sein. Finally, in a last variant, a second pocket can be made integral with the transparent pallet (4). This second pocket is preferably filled with air so as not to affect the passage of radiation, this pocket aims to improve the comfort and the compression applied to the member. This is particularly important in the case of a mammogram for the comfort of the patient and the equal distribution of pressure on the breast.
Dans les autres applications, telles que par exemple les radiographies du rachis, la table ou le plateau contre lequel le patient va appuyer le dos sera pourvu d'une poche selon l'invention qui pourra être solidarisé ou rendue solidaire par tous moyens de ce plateau, de façon à ce que le gel ou le fluide contenu dans la poche puisse se répartir et égaliser le contraste par exemple entre le rachis cervico-dorsal supérieur et le rachis cervico-dorsal inférieur, et améliorer ainsi la netteté du cliché radiographique dans cette région. In other applications, such as for example x-rays of the spine, the table or the tray against which the patient will press the back will be provided with a pocket according to the invention which can be secured or made integral by any means of this tray , so that the gel or the fluid contained in the pocket can be distributed and equalize the contrast for example between the upper cervical-dorsal spine and the lower cervical-dorsal spine, and thus improve the clarity of the radiographic image in this region .
Avec le procédé et le dispositif de l'invention, appliqués notamment à la mammographie, on a constaté une amélioration notable de la netteté du cliché, une meilleure définition de la glande mammaire profonde du fait d'une meilleure compresseion et d'une filtration du rayonnement diffusé émis par la glande elle-même ainsi qu'une meilleure visibilité des régions cutanées et souscutanées. With the method and the device of the invention, applied in particular to mammography, there has been a noticeable improvement in the sharpness of the image, a better definition of the deep mammary gland due to better compression and filtration of the scattered radiation emitted by the gland itself as well as better visibility of the skin and subcutaneous regions.
D'autres modifications à la portée de l'homme de métier font également partie de l'esprit de l'invention. Other modifications within the reach of the skilled person are also part of the spirit of the invention.
