Abstract

PROBLEM TO BE SOLVED: To improve the quality of an image obtained by an X-ray diagnosis and a magnetic resonance diagnostic device by providing a lying plate made of a fiber-reinforced plastic containing linear organic polymer fibers as a filler op the rack of a bed. SOLUTION: This patient lying device is provided with a rack 3 supported on a floor 6 via two pairs of wheels 4, 5, a lying plate 1 for a patient 2 is arranged on the rack 3, and the lying plate 1 is made of a fiber-reinforced plastic containing linear organic polymer fibers, preferably Aramid fibers, as a filler. The linear organic polymer fibers have an electric insulating property and are suitable for magnetic resonance tomography. The fibers has the same heavy atom concentration, i.e., the same X-ray absorbing characteristic, as that of a plastic host surrounding the fibers. The linear organic polymer fibers are not shown on an X-ray image, thus the quality of the image obtained by an X-ray diagnosis and a magnetic resonance diagnostic device can be improved.

2. Description of the Prior Art Patient recumbent devices of this kind are used, for example, to lay a patient during a medical diagnosis. Due to the complex clinical nature of, for example, skull or spine injury, it is sometimes necessary to diagnose patients with x-rays and magnetic resonance tomography.

The patient recumbent device used for X-ray diagnostics is made of a highly conductive material such as aluminum or carbon fiber reinforced plastic. However, this patient recumbent device is not suitable for magnetic resonance diagnosis due to shading at high frequencies and eddy current losses due to gradient currents. Therefore, for magnetic resonance tomography, a patient recumbent device in which the reclining plate is made of wood or glass fiber reinforced plastic is used. However, both of these substances will exhibit a strong formation in the longitudinal direction of the patient during fluoroscopy. This leads to poor image quality, so the patient's recumbent is replaced if possible before the X-ray diagnosis.

[0006] The patient lying device described in DE 3031841 is used as an operating table and has a lying plate which can be placed in various positions. The reclining board comprises two aluminum frame portions located on both sides, respectively, and a foamed plastic core disposed between the two frame portions. The foamed plastic core has a covering layer made of a composite material having carbon fibers or synthetic organic fibers on its front and back surfaces, respectively. The foamed plastic core and the front and back cover layers form a sandwich plate in which the side frame portions are integrated. This sandwich structure achieves high strength and shape stability on the one hand and improves X-ray qualification on the other hand.

[0010] Fibers made of linear organic polymers have electrical insulating properties and are suitable for magnetic resonance tomography. At the same time, the fiber has the same heavy atom concentration and therefore the same X-ray absorption properties as the surrounding plastic matrix. As a result, the fiber composed of the linear organic polymer does not appear in the X-ray image. Therefore, according to the patient lying apparatus according to the present invention, the same good image quality can be obtained in X-ray and magnetic resonance diagnosis.

In general, it is sufficient for the recumbent plate to consist of fiber-reinforced plastic with fibers of linear organic polymer as filler.

Since fibers made of linear organic polymers are not visible on X-ray images, for example, hand lay-up, pultrusion, etc. can be carried out on reinforced plastics in order to produce a patient lying device or a patient lying plate according to the invention. Processing methods known per se, such as pressing, are advantageously used. In order to further manufacture it, every possible arrangement, fiber length,
All known textile products of orientation or irregularity, such as rovings, twists, fabrics and fleece are used. For the plastic matrix, thermosetting casting resins such as epoxy resins, unsaturated polyesters, vinyl ester resins and suitable thermoplastics such as polysulfones, polyarylethers, polyetheretherketones are used. The thermosetting casting resin is preferably not to reduce the coil quality in nuclear spin diagnostics,

For example, in order to manufacture a reclining plate by a cold compression method, an epoxy resin mold is first produced from a precise reclining plate prototype. Fifteen layers of aramid fiber fabric are laid in the opened mold, and burrs are cut off neatly. The reactant, ie the epoxy resin active in the cold compaction, is then poured, the mold is closed and compacted at a pressure of up to 10 bar. After the epoxy resin is cured, the reclining board is taken out of the mold, and a paint is applied as necessary. Further additional processing is unnecessary due to the properties of the epoxy resin mold.

Fibers made of linear organic polymers are suitable for magnetic resonance tomography because of their electrically insulating properties.
Furthermore, the fiber has the same heavy atom concentration and therefore the same X-ray absorption properties as the plastic matrix surrounding it. As a result, the fiber composed of the linear organic polymer does not appear in the X-ray image. The patient 2 lying on the patient lying device according to the invention can thus be diagnosed without any transfer by all X-rays and magnetic resonance tomography.
