Definitions

  • the invention relates to a radiolucent body support which can be used as part of the lying surface in a patient couch intended for radiation therapy, consisting of a frame with a transparent covering, a central web of the frame dividing the supporting surface into two wings.
  • This body support is used instead of part of the normal lying surface if the patient's body part to be treated is to be irradiated in a treatment phase both directly and from the underside of the support, for which purpose a radiation source, e.g. an X-ray apparatus, which is movable on a circular path in a vertical plane.
  • a radiation source e.g. an X-ray apparatus
  • the wings should be transparent so that the treatment beam can be visibly aligned with the treatment area optically marked on the body part using a pilot light and corrected in the event of unforeseen changes in the patient's position.
  • a known body support of the type mentioned has a rectangular frame with a central web that divides the support into two wings. For each wing, the frame carries a covering made of crossed strings which are anchored to frame parts running in parallel.
  • the frame must be of stable construction to absorb the clamping forces. This requires a material thickness for the frame parts that dampens the radiation too much. The frame is therefore on the side in a backdrop - 2nd
  • a radiolucent body support in which, according to the invention, the frame is H-shaped and at least one of the wings is provided with a covering which is anchored exclusively on the two parallel spars which are connected to one another by the central web. This eliminates the frame parts, which are disruptive due to their radiation-damping effect, and no means for lateral displacement of the frame are required.
  • the spars of the H-shaped frame preferably have a pretension so that they run parallel to one another under the force of the covering.
  • At least one string made of radiation-resistant material for example made of plastic, is provided for covering the wing, which stretches the wing in parallel sections with uniform intervals in a meandering course. Can at the ends of the spars' the covering be enhanced by, for example, another gene string in several Windun ⁇ is stretched from island to island.
  • the covering can be covered with a transparent, radiation-resistant cover film, which is also between the two bars the frame is clamped.
  • Another possibility is to provide a one-part or multi-part, transparent carrier film instead of strings for the covering, which can be reinforced at most on the outer edge connecting the ends of the two spars by a string covering.
  • Fig. 2 top view of the body support
  • Fig. 3 Detailed view of the tensioning device for a cover film on a larger scale.
  • the radiolucent body support shown has an H-shaped frame 1, which consists of two parallel bars 2 and 3 and a central web 4 connecting them and is preferably made of metal, e.g. is made from a tough, hard aluminum alloy, or from a fiber-reinforced plastic.
  • the frame 1 carries a transparent covering, which is divided into two wings 5 and 6 separated by the central web 4, which together form the bearing surface.
  • a string 7 or 8 made of radiation-resistant plastic is provided for covering the two wings, which straddles the wing in question in parallel sections with uniform intervals in a meandering course.
  • the ends of the strings 7 and 8 provided with knots 9 and 10 and the reversing loops 11 are anchored to the bars 2 and 3 of the frame 1, the reversing loops 11 being laid in semicircular grooves in the bars are. Instead of one string each, two or more strings can be guided in parallel.
  • All sections of the strings 7 and 8 are tensioned so strongly, for example with 500 N at a section length of 50 cm, that the sag only reaches a few millimeters when loaded by a patient's body part lying on top.
  • the spars In order to compensate for the deflection of the spars 1 and 2 under the load from the covering, the spars have a pretension.
  • the stringing is reinforced by a further string 12 or 13, which is stretched from spar to spar in several turns which lie one above the other.
  • the entire support surface is covered with a cover film 14, which is also anchored to the two spars 2 and 3 of the frame 1. Details of the tensioning device used to tension the cover film can be seen in FIG. 3.
  • the spars 1 and 2 have a semi-cylindrical longitudinal groove 15 on their underside.
  • a tensioning roller 16 is mounted therein on both sides of the central web 4 and held with a clamping bracket 17.
  • Each tension roller 16 has on its periphery a longitudinal slot 18 into which an edge portion of the.

  • each tensioning roller 16 is provided on the end faces with a hexagon hole 19 for inserting an angled hexagon key.
  • the tensioning roller 16 together with the relevant edge part of the cover film can be fixed in the longitudinal groove 15 on the bar by pressing the clamping bracket 17 by means of screws arranged along the same, one of which is shown and designated 20.

  • the frame of a patient couch intended for radiation therapy normally has a cantilevered beam over which the couch surface extends.

  • the frame may be expedient to equip the frame with radiation-permeable covering only on one of the two wings and to design the other wing in the form of a radiation-impermeable plate.

Abstract

Le support fait partie d'un lit de patient pour thérapie par rayonnement. Ce support est formé d'un cadre en forme de H (1) avec deux traverses (2, 3) parallèles réunies par une tige (4) médiane. Les surfaces porteuses (5, 6) séparées par la tige sont munies d'une nappe transparente de cordage sous tension (7, 8). Cette nappe est fixée exclusivement sur les deux traverses (2, 3). Les bords du support parallèles à la tige médiane (4) ne comportent pas de parties absorbant le rayonnement. Ainsi un traitement dynamique par rayonnement peut se dérouler de façon ininterrompue si la source de rayonnement passe d'un côté à l'autre du support.
