## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority to the German application No. 10 2004 004 842.8, filed Jan. 30, 2004 which is incorporated by reference herein in its entirety.
FIELD OF INVENTION
The invention relates to a facility for setting up system testing of floor and ceiling mountable x-ray systems with radiation protection cabins with radiation-proof, especially lead-lined walls.
BACKGROUND OF INVENTION
Previously radiation protection cabins have been used which are adapted to the x-ray systems to be tested, meaning that one has a plurality of different sizes of radiation protection cabins, with a significant problem being the different radiation protection systems that cannot be monitored manually. The design of the radiation protection in these existing arrangements is very maintenance-intensive and the construction below the ceiling is very non-uniform and thereby inflexible.
SUMMARY OF INVENTION
An object of the invention is thus to create a facility for setting up and system testing of x-ray systems, in which, as well as the use of standardized radiation protection cabins, a simple radiation protection is guaranteed and at the same time it is extremely easy to load equipment into the x-ray protection cabins.
To achieve this object there is provision for each radiation protection cabin to have a sliding door taking up at least a majority of the cabin wall consisting of a number of telescopic lead-lined door elements which can be moved over one another, which are preferably hung from a ceiling mount and freely slidable at a short distance from the floor and separate the internal operational area of the cabin from the operating console for the x-ray system located in front of it, for the door elements to be provided with lead-lined edges overlapping each other in the closed position such that radiation cannot escape to the outside from any point within the cabin through the gap between two adjacent door elements, and for a closure monitoring device to be provided which is linked to the operating system of the x-ray system.
The inventive embodiment of the radiation protection cabins initially produces the major advantage that one wall of the cabin can be slid open almost completely, so that large vehicles can be used to bring the individual components of the x-ray system into the cabin and also take them out of it again. This then also produces the advantage of being able to leave the x-ray system in the largest possible assembled state and send it in this state, so that the assembly at the actual installation site, that is in the hospital or medical practice, can be correspondingly simplified.
The freely slidable door elements, which by their overlapping prevent the escape of radiation, can in any event hang a few centimeters above the floor, since at no location within the cabin where an x-ray system can be positioned is a significant amount of radiation emitted downwards, with the angle of radiation emission always being such that escape underneath the lead-shielded door is not possible. In addition the door elements can also be equipped with sealing profiles facing towards the relevant neighboring door element in the area of the side edges, which adjoin each other as sliding stops when the doors are slid open, with it also being possible to arrange sensors in the area of these sealing profiles, which can be included for the closure monitoring arrangement.
The inventive closure monitoring arrangement ensures that the x-ray system can only be monitored if all door elements are closed to provide a hermetic, i.e. radiation-proof seal. If this is not the case for an element, the control system of the x-ray system is blocked and operation is not possible at all.
In an embodiment of the invention there can be provision for the cabin wall with the sliding door to include at least one fixed part with a hinged door, so that after the x-ray system has been set up, with a largely closed sliding door the subsequent fine adjustment and testing, for which frequent entry into the cabin is required, can be simplified, in that only the hinged door is used to allow the operating personnel through.
At least one door element, preferably all, and also the hinged door, can be provided with lead glass windows.
This is not only more convenient for the operating personnel engaged in installation work within the cabin, since they can see out, but also has the advantage that the testing personnel who perform the system testing from the operating console in front of the closed sliding door can observe the system during the testing and the system can be demonstrated to customers in the testing state. Experience shows that customers frequently come to the plant during the setting up and the system testing in order to view their new x-ray system beforehand in order to assess from a similar constructional arrangement how their system will look later.
In a further embodiment of the invention there is provision for the facility for setting up and system testing of x-ray systems to arrange a number of radiation protection cabins next to each other and behind one another, with the facing rear walls of the radiation protection cabins of the two rows being equipped with sliding doors.
This allows a simple arrangement with power supplied to the cabin from the rear. Only the radiation protection cabins arranged next to one another are separated from each other by solid walls, with these being able to be embodied both as concrete walls and as prefabricated walls which are then provided in the known way with radiation protection plates. The radiation protection cabins of these double rows are preferably open at the top and spanned by mounting rails, which are embodied so that the hanging of sliding doors is possible and on the other hand any conceivable assembly of ceiling mountable x-ray systems. The size of the radiation protection cabins is designed in this case such that in each cabin the assembly and system testing of each x-ray system is possible, meaning that different sizes of radiation protection cabins no longer have to be provided for individual types of x-ray systems, since these would not allow a system setup in accordance with the invention and obviously would not provide the free choice and accessibility of the radiation protection cabins which ensures an optimum operating sequence.
The system cabinets arranged within a radiation protection cabin for system testing should be arranged in the area of the rear wall behind slidable lead curtains.
In addition it also falls within the framework of the invention for the operating console of each cabin to be separated by spaced, removable posts anchored in the floor from the roadway between the cabin rows. This open embodiment improves communication within the test hall and also safeguards the operators at the consoles from transport vehicles moving behind them to assemble and dismantle x-ray systems in other radiation protection cabins.



BRIEF DESCRIPTION OF THE DRAWINGS
Further advantages, features and details of the invention are produced by the subsequent description of an exemplary embodiment as well as by reference to the drawing. The diagrams show:
FIG. 1 a schematic view of an inventive x-ray protection cabin without the ceiling construction arranged above it,
FIG. 2 a view of the radiation protection cabin, again without the ceiling construction arranged above it, composed of transverse mounting rails and
FIG. 3 a basic diagram of the sliding door overlapping with the lead lining, with the door elements being shown as exaggeratedly thick.



DETAILED DESCRIPTION OF INVENTION
The radiation protection cabin 1 depicted in FIGS. 1 and 2 comprises two rigid radiation-proof side walls 2 and 3. The operating console 4 in front of the cabin 1 is shielded by a largely open construction from the interior 5 which consists of a fixed part 6 and a sliding door 7, in the exemplary embodiment shown in FIG. 2, consisting of three door elements 7a, 7b and 7c. The door elements 7a, 7b, 7c comprise, as can be seen in particular from FIG. 3, as well as the interior lead plate 8 also lead-lined side edges 9, with the door being embodied so that, when the sliding door is in the completely closed state, the individual elements 7a, 7b, 7c overlap so much that it is entirely impossible for x-ray radiation coming from any point in the interior 5 of the radiation protection cabin to penetrate into the outside area through the gap between two overlapping door elements 7a, 7b, 7c. The door elements 7a, 7b, 7care hung on the ceiling construction so that they slide freely and end at a short distance from the floor, making them very easy and smooth to slide. The sealing profiles 10 shown schematically in FIG. 3 and running along the lead-lined side edges 9 of the door elements 7a, 7b, 7c can have contacts built into them which, for monitoring that the door elements are fully closed and thus that the interior 5 of the radiation protection cabin is hermetically sealed, can be linked to a closure monitoring device, which in its turn is connected to the operating system of the x-ray system. Only when all doors are really closed is the x-ray system within the cabin allowed to be put into operation.
In practice a plurality of radiation protection cabins 1, as shown in FIGS. 1 and 2, are arranged in rows next to one another and in addition in a second row behind the first one, with the facing rear walls of these two rows of radiation protection cells also being able to be closed by sliding doors 7′. Embodying the rear wall as a sliding door 7′ in this way, which is opposite a corresponding sliding door 7′, of the cabin of the row behind it, allows power supply to the system from the rear.
The number 11 indicates the system cabinets which can be arranged in the area of the rear wall of the cabin 1 protected behind lead curtains 12 shown by dashed lines in the diagram. The number 13 shows the removable posts anchored in the floor, to protect the operating console of the cabin 1 from the roadway behind it, or in the case of FIG. 2, below the diagram, running along the row of radiation protection cabins.
