  • Electromagnetic locking means releasably hold the rin against rotation in the frame. The detectin ble to and from inoperative positions outside the zone embraced by the carrier ring.
  • the apparatus of this invention is particularly useful in connection with medical and surgical examinations and procedures, wherein X-ray views taken on two coordinate axes are required for determining the exact position of a bid den object.
  • the general object of the present invention to provide means for establishing the radiation and detecting units of X-ray apparatus of the character described in a fixed to one another while permitting them to be very readily adjustable as an ensemble, so as to avoid the need for adjustment and readjustment of those units relative to one another with each new, setup, but whereby the zone around the object to be examined is left readily accessible and whereby repositioning and rearrangement of the examining setup can be accomplished very quickly and easily.
  • FIG. 1 is a perspective view of apparatus embodying the principles of this invention, together with its associated equipment, set up and arranged for a medical or surgical X-ray examination of a patients leg;
  • FIG. 3 is a sectional view on a larger scale taken on the plane of the line 3-3 in FIG. 2;
  • FIG. 5 is a detail perspective view of one of the detecting units in its relation to the carrier ring and particularly showing the means by which said unit is mounted on the carrier ring;
  • FIG. 6 is a view taken on the plane of the line 6-6 in FIG. 2.
  • FIG. 1 illus trates X-ray apparatus set up for examination of a leg of a medical or'surgical patient and incorporating the apparatus of this invention which is designated generally by 5.
  • the control system for the X-ray apparatus can comprise a conning bench 15, preferably mounted on wheels, in which is housed the high tension current supply for the radiation units and on which are located the necessary controls and monitoring instruments for the apparatus as well as a viewing screen connected with the detecting units.
  • the apparatus of the conning bench is connected with the X-ray apparatus by means of cables 16.
  • the apparatus of this invention (best seen in its general arrangement in FIG. 2) comprises a rigid frame 17, preferably annular, which has its axis horizontal and which is supported on upright tubular legs 18 and 19 that are rigidly secured to the frame at opposite sides thereof.
  • the frame 17 supports an inner carrier ring 20 which is rotatably mounted therein and on which are mounted the radiation units 6 and 7 and the detecting units 8 and SI.
  • the frame 17 and legs 18 and 19 are wheel mounted to provide a stable but readily maneuverable tricycle chassis.
  • one leg I8 has at its bottom an elongated horizontal foot 21 which is supported on a pair of steerable wheels 22, one under each of its end portions, while the other leg 19 is supported on a-single castered wheel 23.
  • the foot 21 can be mounted on the leg 18 to swing about the axis of said leg and can be locked in various positions of such swinging motion by means of a clamping screw 29.
  • the wheels 22 on the foot 21 are steerable in unison about upright axes by means of a handwheel 23 concentric with the leg 18.
  • each of the legs 18 and 19 is made of telescoping members or is otherwise arranged to be adjustable in length by means of a crank 28 connected with a self braking jack screw or the like within the leg.
  • the carrier ring can be made in two axially adjacent parts 31 and 32 which have coaxial interengageable circumferential shoulders, as at 33, to confine them to concentricity.
  • the carrier ring parts are connected by circumferentially spaced bolts 34 that extend parallel to the carrier ring axis.
  • the ring parts On their adjacent peripheral edges the ring parts have substantially large bevels 35 and 36, respectively; which cooperate, when the ring parts are assembled, to define a V-shaped radially outwardly opening circumferential groove that opposes a V- shaped inwardly opening circumferential groove 37 in the annular frame 17.
  • Balls 38 are confined between the opposing surfaces of these grooves to provide bearings by which the carrier ring is confined to rotation in the frame.
  • Each of the carrier ring parts 31 and 32 has a radially outwardly opening circumferential groove 39 which opens to an opposite radially inwardly opening groove .40 in the frame, and these two sets of grooves cooperate to define a pair of annular chambers 41 and 42 that are conjointly defined by the carrier ring and the frame. Sealing rings 43 confined between the frame and the carrier ring seal'the annular chambers 41, 42 to prevent the entry of dirt between the carrier ring and the frame.
  • the X-ray tubes and detecting units are mounted on the ring to partake of its rotation relative to the frame and its other movements as the frame is raised and lowered and moved about on its wheels, the radiation axes of the X-ray tubes will always be perpendicular to one another and to the ring axis, and the detecting units can always be in the proper coaxial and spaced relationship to their respective radiation units. Hence it is not necessary to make adjustments of these units whenever the radiation axes are reoriented.
  • the subassembly comprising the carrier ring and the radiation and detecting units is preferably statically balanced.
  • the carrier ring can be releasably locked in any desired position of rotational adjustment by braking means comprising a strip 44 of rubber or the like that extends all around the bottom of the groove 39 in the carrier ring that defines the chamber 42.
  • this strip has regular transverse ribs 45.
  • an electromagnetically actuated shoe 46 Secured to the frame, and housed within the annular chamber 42 at each of a pair of diametrically opposite locations is an electromagnetically actuated shoe 46 that is provided with transverse ribs which are matingly engageable with the ribs 45 on the strip 44.
  • the shoe Normally the shoe is biased into engagement with the strip, as by means of springs 48 that react between the frame and the shoe, but upon energization of the electromagnet the shoe is drawn out of engagement with the strip to release the carrier ring for rotation.
  • the electromagnets which actuate the shoes 46 can be energized under the control of a control box 47 on the frame, connected by suitable cables with the electromagnets and the conning bench 15.
  • Each of the detecting units 8 and 9 is secured to the carrier ring 20 by means of a hingelike connection, generally designated 49, by which it can be readily swung to an inoperative position in which it is outside the zone embraced by the carrier ring, to present the least possible interference a surgeon working in that zone, and to an operative position in which it is properly aligned with and spaced from its radiation unit.
  • Each of the connections .49 (see FIGS. 5 and 6) comprises a generally L-shaped bracket 50 having one leg 51 that overlies the radially inner surface of the carrier ring and is secured thereto, and another leg 52 that overlies one axial face of the carrier ring and the annular frame 17 and projects radially outwardly beyond the latter.
  • lugs 56 On the outer face of the flange 54 there are fixed mounting lugs 56 through which slidably extend a pair of parallel rods 57 that have their opposite ends fixed to the detecting unit.
  • the lugs and rods cooperate to confine the detecting unit to motion relative to the flange 54 in directions parallel to the viewing unit axis and to the faces of the flange.
  • crank handle 60 is axially slidable on the spindle so that when not in use it can be slid rearwardly to an out-of-the-way position in which its actuating knob is received in a recess 61 in the front of the detecting unit.
  • a sector-shaped plate 62 is secured to the flange 54 to pass edgewise through a slot in the outer leg 52 of the bracket 50, and it has notches 63 in its curved edge in which can be engaged a latch 64 that is mounted on the face of the leg 52 that is remote from the flange 54.
  • the radiation units 6 and 7 can also be secured to the carrier ring by means of attachments similar to the hinge connections 49 described above, so that they too can be swung to operative and inoperative positions.
  • B. means mounting the radiation units at circumferentially spaced locations on the carrier ring and for radiation in directions substantially radially inwardly of the ring;
  • a carriage comprising an annular frame cooperable with the carrier ring to coaxially carry the same and which has its axis substantially horizontal;
  • A. a carrier ring comprising l. a pair of axially adjacent ring parts having:
  • D. means providing a steerable wheeled chassis on which the frame is rigidly supported with its axis substantially horizontal and providing for heightwise adjustment of the frame;
  • E. means securing said units to the carrier ring at circumferentially spaced locations thereon, with the axes of the radiation units substantially perpendicular to one another and to the frame axis and with each detecting unit substantially diametrically opposite'its radiation unit.
  • B. means mounting the radiation units at circumferenttally spaced locations on the carrier ring and for radiation in directions substantially radiallyinwardly of the carrier ring;
  • C. a carriage comprising 1. an annular frame and 2. means mounting the'frame with its axis horizontal, said mounting means providing for heightwise adjustment of the frame and for horizontal movement thereof in all directions;
  • D. means coaxially mounting the carrier ring on said annular frame for free rotation of the carrier ring about its axis;
  • a strip of rubberlilte material that extends circumferentially around the carrierring and has a surface facing the frame that defines numerous circumferentially spaced ribs that project toward the frame;
