Abstract: In an X-ray radiation source, a counter wall made of alkali-containing glass, out of walls of a housing of an X-ray tube, is arranged opposite to a high-voltage region VH of a power supply unit including a high-voltage generation module which generates a negative high voltage to be applied to a filament. This configuration prevents an electric field from being generated in the counter wall and thus suppresses precipitation of alkali ions from the glass. Therefore, it prevents change in potential relationship between electrodes at different potentials such as the filament, grid, and target and prevents occurrence of a trouble of failure in maintaining a desired X-ray amount, thus enabling stable operation to be maintained.

Abstract: Anti-scatter plates are used to attenuate secondary radiation so that it is not detected by a detector array. However, anti-scatter plates often cast dynamic shadows on the detector array which results in noise in signals produced by the detector array. As disclosed herein, an anti-scatter grid comprises at least two anti-scatter plates. A percentage difference in the shadows cast by the first and the second anti-scatter plates is substantially zero (e.g., causing uniform percentage change in shadows cast on the detector array). Additionally, the shadows that are cast by the anti-scatter plates may be substantially static. In one embodiment, this is accomplished by having a top surface of an anti-scatter plate that has a transverse dimension that is less than a bottom surface of the anti-scatter plate.
