Description

Radiography system with a carrier unit mounted to the ground

Technical Field

The invention relates to a medical radiography system having an X-ray source mounted on a ground-mounted, load-bearing carrier unit.

Background

Radiographic systems are known which have a head rail system mounted on a roof, on which at least an X-ray detector is fixed by means of a head frame. The head rail system for the head frame must be mounted or anchored in or on the ceiling of the treatment room. The installation is usually carried out individually for each treatment room and requires more or less expenditure depending on the ceiling construction of the building in order to carry the load of the mobile roof rack. The introduction and installation of the head rail system is constructively complex and must be prepared prior to the installation of the radiology and/or radiography system. Each room requires a separate preparation which moreover requires a sub-construction which is specifically produced and designed by staticians and which reduces weight. Additionally, the head rail system must be oriented in a horizontal plane straight and additionally parallel to the floor of the treatment room in order to ensure precise functioning of the radiography system.

Furthermore, the installation of a conventional radiography system requires additional expenditure for laying the cables. Since the power generating cabinets cannot usually be located directly in the clinic, a part of the system cabling has to be pulled into other rooms, which do not necessarily have to be located on the same floor. This requires a preparation in terms of construction, which entails a time and economic outlay.

A common radiography system generally includes an examination bed, a base frame (also referred to as a wall-mounted reticle)

) And a top frame, the top frame carrying the X-ray source. In order to be able to realize X-ray detectors which are movably arranged in the examination table and in the wall-mounted fluoroscope for the known recording processes in radiography and fluoroscopy, the head frame must be movable in the horizontal plane in the X-and y-direction. The movement can generally be effected in a head rail system arranged at 90 degrees to each other, in which head rail system the head slide of the head frame is movably accommodated. The height position of the X-ray source can be moved along the z direction by a telescopic tube movement mechanism of the top frame. Depending on the arrangement and spacing of the examination bed and the wall-mounted wire filters in the treatment room, correspondingly large movement paths of the head frame in the x and y directions are required.

Disclosure of Invention

The object of the invention is to provide a medical radiography system which enables simple installation of the radiography system with reduced constructional measures in the preparation phase of installation.

Said object is achieved according to the invention by a medical radiography system.

The invention relates to a medical radiography system for recording an examination region, having an X-ray source and an X-ray detector. The X-ray source is fixed on a load-bearing carrier unit mounted to the ground. The carrier element is designed such that the position of the X-ray source is adjustable in the spatial direction of three, in particular cartesian coordinate systems, and the orientation of the X-ray tube to the X-ray detector is adjustable by means of a tiltable or rotatable orientation element.

The radiography system can in particular be a so-called radioscopy system, which is suitable for radiographic and radioscopic examinations. The X-ray detector and the X-ray source are preferably mechanically separate, i.e. not connected to each other via a C-arm or a U-arm, for example. The X-ray source is mechanically separately movable relative to the X-ray detector. Mounted to the ground means that the carrier unit is fixedly mounted on the ground and immovable along the ground.

The carrier unit enables, by means of the design of the carrier unit, an adjustable height or movement range of the X-ray source in the vertical direction, so that the definition is essentially independent of the room height. Irrespective of the room height, which only has to have a minimum height, the medical radiography system can be installed and built on the ground substantially without structural changes to the ceiling in the examination room. In particular in the case of unusually high ceilings, the construction of the radiography system according to the invention is simplified without increasing the matching effort and/or the construction effort for the dimensions of the medical radiography system. Advantageously, installing the radiographic system can require only ground installation of the various components, not a roof or walls.

The orientation element is designed such that the X-ray source is rotatably mounted, so that the orientation of the X-ray source can be adapted to the detection region of the X-ray detector. This is particularly advantageous since the medical device allows the use of different or multiple X-ray detectors or multiple X-ray detector positions. Standard configurations of radiographic systems can include optimized detector coverage in or on the couch and in or on the wall-stand wire filters.

The top frame can be carried by the upright elements, i.e. by the table legs or the column-engaging location elements in the examination room beside the examination table. Advantageously, the ceiling construction required today for the head frame is no longer required, and the radiography system comprises a carrier unit as a replacement for the usual ceiling construction or for the ceiling-side suspension for moving and positioning the X-ray detector.

The effective range of z-motion of the X-ray tube along the room height is independent of the room height, since the radiography system can be installed essentially always identically above the building surface. The radiography system advantageously has a carrier unit similar to a common ceiling construction, which replaces the common ceiling construction with load-bearing anchors in the roof. Advantageously, the radiography system according to the invention is enclosed in a container for mobile application on a load-carrying vehicle or a ship.

Only a floor installation of the individual components of the radiography system can be required, i.e. no roof or walls for installation are required, and the radiography system can be installed, for example, in a room that is too large for a common radiography system without having to make constructional changes to the walls or roof. Advantageously, the radiography system can be connected via a socket system without further room preparation and wiring. Furthermore, the radiography system can be based on, for example, a modular system with different carrier elements.

Advantageously, the invention enables an integrated carrier unit or an integrated top frame in a radioscopy system, which is composed of a plurality of individual components. A standard configuration of a radiography system with optimized detector coverage can be designed for the least required room size. Advantageously, the entire radiography system can be introduced as a component into a treatment or examination room and built, wired and calibrated there. Construction and commissioning can advantageously be carried out quickly and without affecting the building installations previously required.

According to an aspect of the invention, the carrier unit further comprises a first stand element and a position element. The carrier unit includes a vertical first upright member mounted to the ground. The carrier unit comprises a longitudinally adjustable position element in a horizontal plane mechanically connected to the first upright element.

The vertical upright element extends with its longitudinal axis to the floor along the z-direction or along the room height or along the surface normal. Advantageously, the ceiling mounting of the X-ray source can be eliminated.

According to one aspect of the invention, the first stand element is height adjustable. By means of the height-adjustable first upright element, the head frame or the height element can advantageously be dispensed with. The orientation element can in this case be mounted directly on the position element.

By means of the height-adjustable first upright element, the head frame or the height element can alternatively have a smaller movement area or height area, so that weight savings can be achieved for the head frame and thus also for the position element.

According to one aspect of the invention, an examination table is provided on the first upright element. The examination table is in particular height-adjustable and is optionally arranged on the first vertical element so as to be rotatable or tiltable.

According to one aspect of the invention, the longitudinally adjustable position element comprises a telescopic tube movement or a bending joint movement. So-called table legs in the form of first upright elements with an examination table arranged thereon can comprise cantilevers in the form of position elements which are rotatably supported thereon. The position element has a movement mechanism. One embodiment is a telescoping tube movement mechanism that is longitudinally adjustable. Another embodiment of the longitudinally adjustable cantilever can be a bending joint motion mechanism. Preferably, the first upright element is height-adjustable, wherein the height element can advantageously be disposed of if necessary.

A further movement mechanism in the form of a height element or a head frame is arranged on the position element so as to be longitudinally displaceable or longitudinally adjustable, for example in the form of a telescopic movement mechanism, i.e. a telescopic tube movement mechanism, or another movement mechanism which enables a vertical positioning of the X-ray source.

By additional rotation of the X-ray tube or its shield, a longitudinal movement of the X-ray tube along the same longitudinal axis as the detector which is longitudinally movable in the examination table is possible. Depending on the size of the desired playing area of the upper frame, one or more stand members may be provided in the alternative to the legs.

According to one aspect of the invention, a head rail element is fixed as a position element on at least one of the upright elements. The X-ray source is movable in a plane parallel to the ground by means of a head rail element.

Alternative spatial extensions of the movement for the head frame are conceivable, for which an elongated rail can be constructed according to an embodiment. In the extension of the rail for the head frame, it is also possible to use other standing elements for the support. The head rail element can be fixed on the standing element. By means of the head rail system, the head frame can be moved in the x and y directions. An examination table can be arranged in particular on the first upright element.

According to one aspect of the invention, a radiography system has a second upright member connected to a position member, the second upright member having a wall-mounted wire filter integrated thereon. The connection between the first and second stand units can here be a support of the head rail system in common. An expansion device in the form of a wall-standing wire filter can use a second standing element or carrier column. The second upright element can be assigned a guide and a drive unit on which a detector slide of the X-ray detector is mounted.

According to an aspect of the invention, the carrier unit further comprises a height element and/or an orientation element. The carrier unit comprises a vertical height element connected to the position element, the height of which is adjustable, and/or an orientation element connected to the height element or the position element, on which the X-ray source is arranged. Advantageously, the function of a conventional ceiling-mounted head rail system can be simulated in the form of a floor-mounted carrier unit.

According to one aspect of the invention, the height element is a head frame. The distance between the X-ray source and the X-ray detector can be adjusted by means of the head frame. The top frame is carried by a carrier element. As little x and y movement as possible is advantageous for a carrier unit mounted to the ground.

According to one aspect of the invention, an additional fastening of the carrier unit is formed on the wall or ceiling, in particular for stabilizing the carrier unit. The additional support by means of fastening points on the room corners or room walls can advantageously be used to save on the second or further vertical units.

According to one aspect of the invention, the generator or/and the associated components of the X-ray tube are integrated in the carrier unit, in particular the first stand element. The generator and possibly other (hardware) components can for example be stowed or integrated in the first upright element in particular. If the generator is arranged on the first upright element, a particularly short HV cable connection can be advantageously used for the X-ray source. The entire cable connection between the individual components extends above the carrier unit. Advantageously, the outlet system can be implemented without room preparation and wiring. The component can be a hardware component, an electronic component, a vision computer, a cooling device, or the like.

According to one aspect of the invention, the carrier unit comprises radiation protection walls. The radiation protection wall can form a radiation protection capsule. Behind the radiation protection wall, a monitor and an operating panel can be arranged, which are protected against radiation by the radiation protection wall. Advantageously, a separate control room can be superfluous.

Furthermore, ceiling lighting, light effects, monitor carriers, suspension solutions for the patient, operating aids, such as patient lifts, can be included in an overhead suspended manner by the radiography system.

According to an aspect of the invention, the X-ray detector is comprised by another carrier unit or another position element. The X-ray detector can likewise be mounted on the carrier unit or on another carrier unit. The X-ray detector can be mounted within the carrier unit via a second head rail system, wherein the two head rail systems are arranged one above the other. Alternatively, two position elements with a movement mechanism can be arranged one above the other on the first upright element. Alternatively, the position element in the form of a head rail system can be combined with a position element having a movement mechanism.
