Abstract

X-rays images produced intensity apparatus has a vessel with holding the electrodes. According to the present invention, an arrangement of a vessel (1) and an input screen substrate (3) are both being made of aluminium. An insulation layer (7) on the inside wall of the vessel (1) mounts the electrodes (2) and a fluorescent substance layer (8) is applied directly on the input screen substrate (3). The input screen substrate (3) is preferably joined to the vessel (1) as a whole.

Description

The X ray image intensifier
The present invention relates to a kind of X ray image intensifier that has the container that hold electrodes uses.
To disclose a kind of X ray image intensifier tube by EP 0360906 A1, in this X ray image intensifier tube, to have made and assembly fee usefulness in order reducing, electrode system is placed on the inside of the X ray image intensifier tube tube wall between the phosphor screen as lining.This image intensifier tube is made drum shape tube wall by thin plate, and the one end is connected with the input phosphor screen, and the other end is welding on the vitreum, also is provided with an output phosphor screen on this vitreum.An insulating barrier is arranged in the inside of electrode suppor, and this insulating barrier is by lacquer, pottery, glass or preferably constitute by a kind of metal oxide, by spray or brush coated on.Known, electrode suppor also can be by a kind of insulating material, and for example pottery or plastics are made, can cancel the coating insulating barrier in this case.
Disclose a kind of X ray image intensifier tube by DE 4342219 C2, fluorescence coating directly is coated on the support on its input phosphor screen, and this support constitutes input window simultaneously.Support connects together by welding and vacuum chamber.
The objective of the invention is to, design a kind of X ray image intensifier, so that its manufacturing cost and producing cost reduce.
The objective of the invention is such, a kind of X ray image intensifier promptly is provided, it has the container of hold electrodes and is used for the support of cutout screen, inwall at container has an insulating barrier, on insulating barrier, settling electrode, it is characterized in that, described X ray image intensifier also comprises the input screen substrate, wherein container and input screen substrate are to make and be made into an integral body by aluminium, fluorescent material layer directly is applied on the input screen substrate, support is made of pottery, and the support vacuum-tight is connected between cutout screen and the container, with container, input screen, cutout screen constitutes the vacuum envelope of described X ray image intensifier together.
It is favourable that the input screen substrate of the container of hold electrodes and X ray image intensifier tube is made up of aluminium basically.
It is integrally manufactured making container and input screen substrate, can abandon interconnection technique thus fully, and omits a course of work therefrom.
The support of cutout screen is made of pottery, and then container can preferably link together with simple mode vacuum-tight and support by friction welding.
Other advantage of the present invention and details can by following to an embodiment explanation and diagram and provide in conjunction with claim.
Embodiment according to X ray image intensifier of the present invention has been shown in the accompanying drawing.
On X ray image intensifier tube shown in the drawings, is furnished with a container 1 that is used for hold electrodes 2.The input screen substrate represents with Reference numeral 3 that in the front of container the support of cutout screen 4 is represented with Reference numeral 5.Inwall at container 1 has an insulating barrier 7 that preferably is made of glaze, settles electrode 2 on this insulating barrier.Electrode 2 can be made by metal or by the polyamide that is rich in carbon black.By the sulfuration zinc-silver of activation, or by the gadolinium oxysulfide that has added terbium, or the fluorescent material layer 8 that preferably is made of the caesium iodide that added sodium directly is coated on the input screen substrate 3.
According to the present invention, container 1 is made by aluminium, and it links together with the support 5 that is made of pottery by friction welding or preferably by ultrasonic bonding.
Within the scope of the present invention, container 1 is made into an integral body with input screen substrate 3, can abandon interconnection technique like this.
Input screen substrate 3 is made by aluminium basically, can be made into the enclosed globe shade or the lid shape of an integral body.In order to obtain a smooth especially surface, aluminium can be obtained a surface uniformly through the smooth roller of single or double, the crystal structure of fluorescent material layer 8 also is uniformly like this, preferably obtains a coarse-grain structure (Facettenstruktur).

Claims (4)

1. X ray image intensifier, it has the container (1) of hold electrodes (2) and is used for the support (5) of cutout screen (4), inwall at container (1) has an insulating barrier (7), on insulating barrier, settling electrode (2), it is characterized in that, described X ray image intensifier also comprises input screen substrate (3), wherein container (1) and input screen substrate (3) are to make and be made into an integral body by aluminium, fluorescent material layer (8) directly is applied on the input screen substrate (3), wherein, support (5) is made of pottery, and support (5) vacuum-tight is connected between cutout screen and the container, with container, the input screen substrate, cutout screen constitutes the vacuum envelope of described X ray image intensifier together.
2. according to the described X ray image intensifier of claim 1, it is characterized in that being connected by friction welding or supersonic welding between described support (5) and the container (1) fetches realization.
