Definitions

  • the invention relates to an X-ray emitting device of the type in which an X-ray tube and, means for supplying the latter with high voltage and low voltage, are assembled to form a single block.
  • the invention particularly relates to means for facilitating the construction and maintenance of such a device.
  • Document US-A-1987790 discloses an X-ray emitting device which comprises a first enclosure containing an X-ray tube immersed in an electrical isolation fluid.
  • a second enclosure contains supply means for supplying the X-ray tube with high voltage and low voltage.
  • the supply means are also immersed in electrical insulation fluid.
  • the two enclosures are sealed relative to each other and made of an electrically insulating material.
  • the enclosures are formed so that the first enclosure is disposed in a cavity of the second enclosure.
  • the cavity is formed using partitions which constitute a means of guiding and holding the first enclosure.
  • Radiology installations in particular for medical diagnosis, include, to produce X-ray radiation, an X-ray tube and power supplies producing the different voltages necessary for the operation of the X-ray tube.
  • the X-ray tube and the power supplies can be arranged in two configurations which differ from each other, mainly in that, in the first configuration, the X-ray tube is separated from the power supplies and the electrical connection is made using cables with high electrical insulation; whereas in the second configuration, the X-ray tube and the power supplies are combined in a single block, which avoids the use of cables with high electrical insulation.
  • the high and low supply voltages of the X-ray tube are transported from the inside of the tank to the inside of the sheath, using two cables with high electrical insulation, the first of which brings high voltage negative and the supply of the filament (s), on the cathode side, and the second of which brings the positive high voltage and the low supply voltage of the anode motor to the anode side.
  • the X-ray unit is a particularly mobile element, and the cable or cables with high electrical insulation which are attached to it have significant discomfort due to their very high mechanical rigidity necessary to obtain the electrical insulation qualities required. It can be noted on this point, that for a supply of the X-ray tube with a relatively high high voltage, this supply is rarely of the monopolar type only because of the too great mechanical rigidity that the cable with high electrical insulation should include.
  • one of the concerns of manufacturers of radiological installations is to ensure that all the external surfaces of the sheath are metallic and brought to earth potential, and that there is electrical continuity the along this sheath, along the cable or cables with high electrical insulation and along the tank containing the generator.
  • the cables with high electrical insulation are wrapped in a metallic layer, and all the arrangements are made so that on the whole, and after connection of the cables with high electrical insulation, no non-metallic part can be reached from the accidentally outside.
  • An exception is however made for an exit window, formed in the protective sheath, and through which the useful beam, that is to say the X-rays used to produce a radiographic image, exits.
  • the X-ray emitter comprises a metal enclosure, so as to be isopotential also like the protective sheath of the X-ray unit of the first configuration.
  • This metallic enclosure or sheath is filled with an electrically insulating oil and contains the X-ray tube, as well as all the elements useful for its supply such as for example those described in the case of the first configuration; the different connections between the X-ray tube and the power supplies being made inside the sheath.
  • one of the main advantages of the X-ray unit compared to the arrangement described in the first configuration resides in that it does not require cables with high electrical insulation, and in that the cable or cables which it attached are cables that carry low voltage and are relatively flexible.
  • the X-ray unit has a significant drawback in terms of its maintenance, in particular for the replacement of an X-ray tube which, necessarily, requires the return of the entire X-ray unit to the factory.
  • the replacement of an X-ray tube requires intervention at the level of the connections between the latter and its power supplies, after having emptied the sheath of the oil which it contains. It is necessary then, after replacing the X-ray tube and before carrying out a functional check, fill the sheath again with insulating oil; this latter operation being particularly delicate owing in particular to the fact that the oil must not contain any air bubbles which could degrade the electrical insulation.
  • the invention relates to an X-ray emitting device of the type forming a single block similar in its form outside to an X-ray unit, but whose new arrangement makes it possible to avoid the drawbacks presented by the latter, in particular in terms of maintenance.
  • FIG. 1 shows, by way of nonlimiting example, an X-ray emitting device 1 according to the invention.
  • the emitting device 1 comprises a metal sheath 2, made of aluminum for example.
  • the inner walls of the sheath 2 are coated with a layer 3 of lead intended to form a shielding shielding against X-rays.
  • the sheath 2 has a substantially cubic shape, and constitutes a box closed by a cover 4.
  • the cover 4 is removable or, as in the nonlimiting example described, mounted on a hinge 5 secured to the sheath 2 so as to be able to be lifted in rotating around the hinge 5, as symbolized by an arrow 6 in order to allow access to the interior of the sheath 2.
  • the sheath 2 contains a first and a second enclosure 7, 8 each sealed and filled with an electrically insulating oil 9, the first enclosure 7 containing an X-ray tube 10, and the second enclosure 8 containing power supplies 11, 12 necessary to supply the supply voltages of the X-ray tube 10.
  • These power supplies are constituted, in the nonlimiting example described, on the one hand, by a high voltage generator 11, conventional, producing a rectified high voltage HT intended to be applied between an anode 30 and a cathode 31 of the X-ray tube 10, and on the other hand, by a transformer insulation 12 delivering a low voltage BTF intended to be applied to a filament 32 of the cathode 31.
  • the two enclosures 7,8 are applied one against the other in order to facilitate the electrical connections between these two enclosures 7,8, by means allowing them to be easily separated from one another.
  • the two enclosures 7, 8 are made of an electrically insulating material which, in a first version of the invention, is a material in itself conventional, such as for example epoxy resin.
  • the first and second enclosures 7, 8 respectively comprise first and second side walls 18, 19 of which only the two walls perpendicular to the plane of the figure are shown, and respectively comprise first and second bottom plates 20, 21, as well as first and second top plates 23,23; the first top plate 22 constitutes a cover of the first enclosure 7, and the second top plate 23 constitutes a cover of the second enclosure 8.
  • their side walls and bottom plates respectively 18,20 and 19, 21 can be made in one piece, for example by molding.
  • the first top plate 22 of the first enclosure 7 is fixed to the first walls 18 by conventional means (not shown), by means of seals 25, so as to ensure the sealing of the first enclosure 7.
  • the second top plate 23 seals the second enclosure 8, also using seals 25.
  • the second top plate 23 is fixed to internal flanges 26 with which the second walls 19 are provided, so as to facilitate the production of partitions 27 which extend the second walls 19 and project beyond the second top plate 23, and which thus form between them a housing 24 in which the first enclosure 7 is arranged.
  • the second enclosure 8 is disposed on a bottom 16 of the sheath 2, and the first enclosure 7 is located on the side of the cover 4 of the sheath 2, supported by its bottom plate 20 on the second top plate 23 of the second enclosure 8.
  • the high voltage generator 11 is supplied by a low voltage alternating power supply BTA which is transported in the second enclosure 8 by a low voltage cable 36.
  • the low voltage cable 36 passes through the sheath 2 and enters the second enclosure 8 by a crossing waterproof 37; the low voltage cable 36 being itself connected, outside the sheath 2, to a conventional low voltage power source (not shown), as constituted for example by the 50 or 60 Hertz distribution network.
  • the low voltage cable 36 has two wires 35 carrying the low supply voltage BTA, which are applied to inputs 33, 34 of the high voltage generator 11; a third wire 15 of the low voltage cable 36 carries the potential of the earth or mass.
  • the high voltage generator 11 delivers the negative polarity -HT of the high voltage by a first output terminal 40, and delivers the positive polarity + HT by a second output terminal 42.
  • the high voltage supply of the X-ray tube 10 is of the monopolar type, and the second output terminal 42 is connected to the third wire 15 of the low voltage cable 36, so that the positive + HT polarity is brought to the potential of the earth or ground, the sheath 2 also being at ground potential.
  • the high voltage supply could be different according to configurations in themselves well known to those skilled in the art, such as for example monopolar with the negative polarity of the high voltage -HT to ground, or else according to a symmetrical arrangement (not shown) where the negative and positive polarities -HT, + HT of the high voltage are respectively negative and positive with respect to ground.
  • the different voltages necessary for the operation of the X-ray tube 10 are transported from the second enclosure 8 to the first enclosure 7, using complementary connectors with which these speakers are provided.
  • the bottom plate 20 of the first enclosure 7 comprises male connectors M1, M2, ... M5
  • the top plate 23 of the second enclosure 8 comprises female connectors C1, C2, ..., C5 in the same number, to each corresponding male connector a female connector.
  • the male and female connectors M1 to M5 and C1 to C5 are mounted respectively in the bottom plate 20 and the top plate 23, in the thickness direction of the latter, at the possibly using conventional seals (not shown), so that the interlocking of these connectors is carried out in a simple manner when the bottom plate 20 of the first enclosure 7 is supported on the top plate 23 of the second enclosure 8; the first enclosure 7 being guided by the partitions 27.
  • the X-ray tube 10 comprises a vacuum-tight envelope 70 in a conventional manner.
  • the envelope 70 contains the cathode 31, carried by a support 60 at a first end 71 of the envelope 70, and disposed opposite the anode 30.
  • the anode 30 is a rotating anode secured to a rotor 72 by means of a metal support axis 77; the rotor 72 is itself carried by a metal support shaft 73 which is fixed at a second end 74 of the casing 70.
  • the rotor 72 cooperates in a conventional manner with a stator 75 located outside the casing 70.
  • the casing 70 is entirely made of an insulating material, glass or ceramic for example, but it can also be metallic on the side of its second end 74, particularly when the high voltage supply is of the monopolar type with the anode 30 at ground potential.
  • the cathode 31 produces, using the filament 32, an electron beam (not shown) which bombards the anode 30 and forms on the latter a focus 80 which constitutes the source of X-radiation.
  • X-ray radiation leaves the sheath 2 through a window 81, in the form of a useful beam 82.
  • the lead layer 3 does not extend in front of the exit window 81.
  • the cathode 32 is shown in a simplified manner by a rectangle containing only the filament 32; but the cathode 31 can contain several filaments without departing from the scope of the invention, each additional filament requiring only an additional electrical connection because, generally, each filament has one end connected to the cathode itself.
  • a first and a second internal connection 92, 93 connect a first and a second end 90, 91 of the filament 32 respectively to a first and a second watertight electrical bushings 94.95 inserted in the casing 70, on the side of the first end 71 of the latter.
  • the first and second watertight electrical bushings 94.95 are connected respectively to second male connectors M1, M2, which are in contact respectively with a first and a second connector females C1, C2.

  • the isolation transformer 12 has a secondary winding 48, and a primary winding 47 which is supplied by the low supply voltage BTA, that is to say that the ends 45 of this primary winding 47 are connected to the wires. 35 of the low voltage cable 36.
  • a first end 46 of the secondary winding 48 is connected to the first output terminal 40 of the high voltage generator 11, that is to say to the negative polarity -HT.
  • a second end 50 of this secondary winding 48 is connected to the second female connector C2, which supplies the filament 32.
  • the second output terminal 42 of the high voltage generator 11 which is at earth or ground potential and which delivers the positive + HT polarity of the high voltage, is connected to a third female connector C3 in which a third male connector M3 is engaged which itself is connected, inside the first enclosure 7, to the metallic support shaft 73: so that the positive polarity + HT or mass is applied to the anode 30 via the shaft support 73, rotor 72 and support axis 77.
  • the stator 75 is supplied in a simple manner by applying to it the low supply voltage BTA, that is to say that inputs 96 , 97 of the stator 75 are connected respectively to a fourth and to a fifth male connectors M4, M5; the fourth and fifth male connectors M4, M5 are respectively engaged in a fourth and a fifth female connectors C4, C5 which are connected to the wires 35 of the low voltage power cable 36.

  • stator 75 can be supplied according to any other conventional configuration, with for example the stator 75 brought to a potential different from that of the rotor 72. It should also be noted that in the context of the invention , the rotor 72 can also be of the magnetic suspension type, this possibly having an influence only on the number of electrical connections that it is necessary to establish between the first and the second enclosures 7,8.
  • the new arrangement of the emitting device 1 according to the invention in which the X-ray tube 10 is mounted in an enclosure 7 filled with insulating oil 9 and in which the supply means 11,12 are mounted in a second enclosure 8 also filled with insulating oil, may worry the specialist and dissuade him from going towards such a solution because it requires two filling operations with isolation oil, while only one single filling operation d oil is necessary in the case of an X-ray unit according to the prior art.
  • this drawback is largely offset by the advantages that this solution brings, by the fact that the two enclosures 7,8 can easily be assembled and electrically connected to each other, and are easily separable from each other: which allows in particular, on the one hand, to easily replace a defective X-ray tube on the site, and which on the other hand facilitates manufacturing by making it possible to build and control separately, the enclosure 7 containing the X-ray tube and the enclosure 8 containing the supply means.

  • the first enclosure 7 By producing with such a material, for example the first enclosure 7, the latter can fulfill the function of protective shielding with respect to X-radiation, which makes it possible to remove the lead layer 3; hence, among other things, a considerable simplification in manufacturing. It should be noted that this also makes it possible to remove the various elements contained in the second enclosure 8 from the action of X-rays, and thus to avoid a relatively slow but certain degradation due to x-rays, of some of these elements such as for example polysulfone insulators.
  • the electrically insulating shielding material is obtained from an electrically insulating base material, an epoxy resin for example, which is loaded with a material with a high atomic number.
  • These high atomic number materials can be electrically insulating materials such as, for example, oxides of tungsten, uranium, thorium or even lead such as minium.
