COLUMN SUPPORT FOR X-RAY APPARATUS This application is a continuation of the now abandoned application, Ser. No. 774,546, filed Nov. 8, 1968, which was a continuation of the now abandoned application, Ser. No. 493,419 filed Oct. 6, 1965. t
For screening and for recording images with the aid of X- rays, in medical examination, it is often required that adjustments of the X-ray beam can be obtained in which the direction of the central axis of the X-ray beam is chosen quite at will. In order to localize foreign bodies or for defining other positions, it isdesirable to penetrate the object in' various directions, which processes require a great accuracy. For this purpose it is known that at different adjustments of the Xray tube and the ray collector the main ray of the X-ray beam is directed through a given point, which condition is fulfilled when the X-ray tube and the ray collector can be displaced in common about two axes at right angles to each other the point of intersection of which lies in the main ray of the beam between the X-ray tube and the'ray collector.
Known devices for carrying out such an examination consistof a column stand provided with a 'horizontalsupporting arm which has a circular cross section and which is rotatably secured to the column. With the supporting arm is movably connected a support for the X-raytube and the ray collector. The movability of the support does not influence the location of the point of intersection of the main ray of the X-ray beam with the axis of rotation of the arm, since this support moves about an axis passing through this point of intersection at right angles to the axis of the supporting arm.
in case of absence of clearance between the various movable parts, a high degree of accuracy may beattained in performing an examination. The accuracy is at a maximum when the position of the point of intersection of the central axis with the two axes remains unchanged while choosing various adjustments of the central axis. Without much trouble, the connections can be established substantially without any clearance, but when a rotatable arm is used, it is not so easy to manufacture the latter so that sagging as a result of the weight of the parts connected thereto is completely avoided. The cause of an insufficient rigidity of the supporting arm must be considered to be the use of an electronic image intensifier with or without an image-recording camera replacing the X-ray screen or the film-holder, which results in a considerable increase in weight.
The invention has for its objecttn avoid this disadvantage and relates to a column stand for supporting the support of an X-ray tube and an X-ray detectorconsisting of an electronic image intensifier tube combined or not combined with an image-recording camera, the support beingadapted to move about two axes at right angles to each other which have a common point of intersection with the central axis of the X-raybeam, which point of intersection is located between the X- ray tube and the X-ray detector. Accordingto the invention, a horizontal supporting arm is rigidly secured to the column stand or to a carriage displaceable along the column, which arm has a circularly curved end face the length of which is at least equal to a quarter of a circle and the center point of which coincides with the point of intersection of. the central axis with the two axes, while a sliding member is displaceable along this end face, which member is provided with a.rotary shaft facing the point of intersection and connectingthesupport of the X-ray tube and the X-ray detector with the sliding member.
The invention will now be described more fully with reference to the accompanying drawing which illustrates a column stand in accordance with the invention in FIG. 1 and a corresponding axis diagram in FIG. 2.
On the floor 1 of a room there isfarranged a column 2 on a base 3 which is displaceable by means of rollers 4 along the floor l. A supporting arm 5 is-fixedly secured to the column 2. This manner of securing the supporting arm has the advantage that the dimension may be large inthe operative direction of the weight of the movable parts so that any sagging due to the mechanical load is prevented.
The end of the supporting arm 5 remote from the column is provided .with a curved end face 6 which constitutes the running face for the rollers 7 by means of which the sliding member 8 can be moved back and forth along the curved path so that it can occupy along the circumference of a quarter of a circle any selected position.
The support 10 is rotatably secured to the sliding member 8 by means of a shaft 9, which support has a bent arm II to which the X-ray tube 12 is secured. .The ray collector 13 is connected by a holder 14 with. a carriage 15 which is displaceable along the support 10, as a result of which the distance from the X-ray tube can be varied by the displacement of the X-ray detector 13. The ray collector is constituted by an electronic image intensifier known per se, while an image-recording camera 16 may be connected thereto.
The beam of rays of the X-ray tube 12 is directed towards the-X-ray detector 13 in the direction of the central axis 17 which is coplanar to the center line of the shaft 9 and the point of intersection of which is at the same time the center point of the curved. end face 6. The displacement of the sliding member 8 along the face 6 causes the support 10 together with the X'-ray tube 12 and the X-ray detector 13 to rotate about an axis at right angles to the said face passing through the point of intersection in the central axis 17. The common displacements renderit possible for the X-ray tube to be displaced along a spherical surfaceso that the central axis .can be adjusted in concave curved surface defining a partial circular are that.
