Abstract

At the present time, there are many kinds of x-ray imaging machines, and the x-ray image intensifier is the key component of it. In the hospitals, those x-ray imaging machines, which are equipped with the vacuum image-intensifier tubes (very heavy), are very ponderous (up- to-100-pound heft). It is particularly difficult to move and operate; by using the MCP x-ray intensifier-tube (it is also a vacuum tube), the system can be simplified, but the field of view is small because of the complex technics of MCP. These years, although the flat-panel detector is very advanced and it has big visual field, it is too expensive to be used in the daily living. In this paper, a new kind of x-ray image intensifier is put forward, which is coupled to million-pixel CCD by lens, is mainly composed of the intensifying screen and the brightness intensifier. It has the advantages of big visual field and low price. At the very beginning of this paper, the new kind of image intensifier and its imaging performance are introduced in detail. Then the performance characteristics of the intensifier are described. It is concluded that the relation between the output brightness that the brightness intensifier detects and the size of the intensifying screen obeys the inverse square law and the resolution of the image intensifier depends on the resolution of its components. After we discussed all these relations among the visual field and the output brightness and the resolution, we put forward the optimal coupling among all parts of the x-ray machine.
