Said endless screw 13 meshes with a first gear 14 fixed to a shaft 15 passing through the rear foot 4 and carrying, on the other side thereof, a second gear 16 meshing with the sector 8.
  • the toothed sector 8 can be replaced, preferably, by a limb of semicircular form which is provided upon its external periphery with a stretched chain engaging with a gear fixed to the shaft 15 and surrounded by two pulleys. This kind of drive system makes it possible to pivot the device between a vertical position such as shown in FIG. 4, and an angled position.
  • the frame 6 has a protective apron 17 and at the top it carries a stretched sheet of plastic material 18 to protect the patient and the mechanical components located inside the frame.
  • This supporting assembly comprises a first column 21 which is motorised to pivot about a first spindle 22 providing a first horizontal axis perpendicular to the longitudinal axis of the frame 6 and preferably located in the plane of the film F, and a second column 23 assembled on the frame 6 in order to be able to pivot about a second spindle 24 providing a second horizontal axis parallel to the first one and likewise located in the plane of the film.
  • the first and second axes 22 and 24 are situated symmetrically relatively to the centre of the frame 6.
  • the free ends of the two columns 21 and 23 are coupled together by means of a first transverse arm 25 whose two ends are respectively mounted to pivot about a third 26 and a fourth spindle 27 carried by the respective ends of the columns 21 and 23, thus forming a first deformable parallelogram with the rear member of the frame 6.

  • the junction between the two branches 31, 32 of the tube-holder arm is articulated on a fifth spindle assembled at the centre of the first arm 25 in order to form a second deformable parallelogram composed of the latter itself, the vertical branch 32, the second arm 34 and the tomography boom 33, so that the central ray of the X-ray beam is directed, during a tomography operation, towards the centre of the film which has to carry out a homothetic motion in relation to said source.
  • the tomography rod 33 is also articulated to the fourth spindle 27 of the column 21 and to a sixth spindle 35 which is displaceable perpendicularly to the plane of the film and defines the plane of tomography.
  • This spindle 35 is mounted on a block 36 on the one hand engaging in a first slide 37 integral with the frame 6 and perpendicular to the plane of the film F and on the other hand engaging with a threaded shaft 38 driven by a motor 39 which controls the displacement of the block 36 along the slide 37.
  • the spindle 35 carries a second slide 40 journalled thereon and containing an opening perpendicular to the spindle 35 for the insertion of the rod 33.
  • the other end of the tomography rod 33 contains an oblong opening 41 in which there engages a roller 42 fixed to an X-ray film handling device (cassette holder) 43 through the me dium of an arm 44.

  • the pivots 49 and 50 carry an elongated frame 51 of U-shaped cross-section which can pivot about said axis. This pivoting is controlled by an electric motor 52 which produces rotation of an arm 53 carrying at its end a roller 54 arranged between a pair of slideways 510 assembled on the bottom edge of said elongated frame 51.
  • the stator of the motor 52 is fixed to the rectangular frame 6 so that rotation of the arm 53 in the anticlockwise direction causes the elongated frame 51 to pivot about the axis defined by the pivots 49 and 50, bringing it from a position parallel to the longitudinal axis of the frame 6, towards a position perpendicular to said axis.
  • the elongated frame 51 in turn carries a hollow elongated component 55 of substantially rectangular crosssection, arranged inside same in order to be displaceable longitudinally in relation to the frame 51.
  • This displacement, guided by the frame 5ll, can be produced by a conventional rack drive (not shown in the ( Figure) where the drive motor is located in a chassis 560 and a pinion coupled to the rotor of the drive motor, meshes with the rack which is fixed to the component 55 for example.

  • These drive devices comprise respective outputs in the form of the shafts 62 and 63 which can rotate about their own axes and can likewise be displaced parallel to the bottom edges (adjacent the film) of the plates 58 and 59.
  • the shafts 62 and 63 carry a rigid patient support plate 64 (preferably made of X-ray quality wood or of a synthetic material transparent to X-rays) having its lateral edges provided with a series of notches which facilitate the immobilization of the patient (a baby for example) bandage wound around both the patient and the plate and retained by the reentrant notch portions by means of a belt 65 of the plate.

  • the support device 47 carried by a cross-member 600 fixed to the frame 6, the fork 48 and the pivots 49 and 50 fitted to the ends of the legs 48 of said fork in order to carry the elongated frame 511 so that the latter can pivot about the axis defined by said pivots.
  • the elongated frame Sll serves as a guide or slideway for the axial displacement of the elongated hollow component 55.
  • the pivoting of the elongated frame 51 is controlled by the motor 52 through the medium of a reduction gear 521 (fixed to the cross-member 600) whose slow speed output shaft 522 (FIG. 6) carries one end of the arm 53 whose other end in turn carries the roller 54 inserted between rectangular blocks 510.
  • elongated component 51 forming a slideway for said roller is equipped on its back face with a rack 51 meshing with a pinion 561 driven by a motor 562 (FIG. 5) through the medium of a reduction gear 563, the whole being covered by a casing 56.
  • This drive makes it possible to modify the position of the component in relation to the frame 51 in order to axially displace the patient in relation to the exposure field.
  • the elongated component 55 comprises, internally, a first shaft 522 passing through it, the ends of which are respectively connected to the arms 56 and 57 supporting the patient carrier plate 67 (which differs from the plate 64 shown in FIG. 3 and will be described hereinafter).
  • This first shaft 552 is rotated by a first motor 553 assembled inside the component 55, through the medium of the gearing 554.
  • the elongated component 55 likewise comprises a second shaft 555 passing through it, and parallel to the first one, which is driven by a second motor 556 through gearing 557.
  • the rotational motion of said second shaft 555 is transmitted through a pair of bevel gears 558 to a threaded shaft 559 (FIG. 7) engaging with a nut or threaded component 580 coupled to the mechanism which displaces (translational motion) the patient carrier plate 67 in directions perpendicular to the axis of the patient.
  • This pair of bevel gears 558 which could equally well be replaced by a transmission system comprising an endless screw meshing with a gear, is housed in a protective casing 561 (FIG. 6) which can pivot about the second shaft 555 and may contain a bearing or location (not shown) to pass the threaded shaft 559.
  • the mechanism of controlling the rotation of the plate 67 is fixed to a rigid chassis or carriage 581 in the form of a flat plate which can slide in a pair of slideways 582 and 583 fixed to the plate 58 and parallel to the bottom edge thereof.
  • the nut 580 is articulated about a pivot fixed to said chassis 581 in order to be able to control the lateral displacement of the shaft 62 (or 63) in different positions of the arm 56 which latter can pivot about the axis of the first shaft 552.
  • Said plate 581 carries furthermore a motor 584 driving an endless screw meshing with a gear 586 to the shaft 62.
  • Said shaft 62 is provided at its end with a device 620 (FIG. 6) (FIG. 5) for the detachable connection of the patient carrier plate 67 which will be described hereinafter.
  • the arms 56 and 57 fixed to the first shaft 552 are respectively articulated at their free ends to pivots 565 and 575 respectively assembled to the top parts of plates 58 and 59.

  • the patient support plate 67 shown in FIG. 5 differs from that 64 of FIG. 3 since it comprises a portion in the form of a plank or board 68 bordered (at a distance of around a fingers breadth) by two members 69 in the form of a slideway for the assembly of bets, handholds etc.. to retain and immobilise the patient who, in this case, will be older (between) 2 and 4 years old for example).
  • the device for dismountably securing the support plates has been designed to make these plates easy to exchange.
  • they each comprise the same quick fitting systems composed of components 620 and 630 each having two recesses preferably disposed symmetrically vis-a-vis the axis defined by the shafts 62 and 63, into which recesses there are inserted on the one hand the fixed studs 641 and 642 and on the other the retractable studs 643 and 644 which are held in position by springs.
  • These patient carrier support plates all have the same length but their widths and shapes differ to accord with the size of patient they are intended for. The availability of several plates which can be rapidly positioned and fitted, makes it possible to prepare patients in advance and thus to reduce the time wasted between examinations.
  • the elongated frame 51 then undergoes a rotation about the axis 49 as a consequence of which the longitudinal axis of the plate, whilst remaining parallel to the table 6, is placed perpendicularly to the longitudinal axis of said table.
  • the table 6 is then inclined until it is vertical (FIG. 4) but the plate can be maintained horizontal by controlling the motor 584 (FIG. 7) which rotates the support 620 (FIG. 5) through the medium of the shaft 62.
  • This rotational movement of the plate in relation to the table 6 is made possible despite its size, because of the fact that the plate can be moved away from the table 6 by inclining the links 56 and 57 using the motor 556. (FIG. 5).
  • the positioning of the plate in relation to the beam is effected by controlling the motor 562 (FIGS. 5 and 6) which is responsible for translating the plate in the direction of its axis, and by controlling the motor 556 (FIG. 6) which controls the translation motion in a perpendicular direction.
  • the distance between the plate and the table (and consequently between the plate and the film plane) is controlled by the motor 553 which controls the orientation of the arms 56 and 57.
  • the orientation of the plate is regulated by the motor 584 (FIG. 7) which causes the plate to rotate about its longitudinal axis.
  • This apparatus is therefore perfectly suited for the examination of small patients, ranging from the newborn to children of 4 to 5 years old.
  • Two support plates have been illustrated, one 64 (FIG. 3) of which is provided for newborn infants, this plate having a small width and being provided with notches for the positioning of retaining bandages or belts, whilst the other 67 (FIG. 5) is wider and has longitudinal attachment bars.
  • These plates are easily detachable so that plates of different shapes and sizes can be used provided that they have the same length and have the same quick-fit systems.
