Imaging with enhanced x-ray radiation

Abstract

The invention relates to an X-ray imaging apparatus (), comprising: a source () for generating X-ray radiation, an object receiving space () for arranging an object of interest for X-ray imaging, an X-ray collimator arrangement () arranged between the source () and the collimator arrangement (), and an X-ray mirror arrangement (). The mirror arrangement () comprises for example two tapered mirrors () facing each other and adapted for guiding X-ray radiation of the source () to the collimator arrangement (). Consequently, the X-ray intensity at the object receiving space () is increased. In order to limit the X-ray radiation to an area, where the X-ray radiation can be utilized form imaging, an angle of spread Θm between the mirrors () and a length LM of each mirror () is adapted, such that a number of total reflections of X-ray radiation, provided by the source (), at the mirrors () is limited. The limitation provides the effect that an angle of reflection Θr of the totally reflected X-ray radiation is limited. Consequently, an X-ray intensity at the object receiving space () is increased while constrains are provided, which prevent a large increase of a width of the X-ray radiation provided at the object receiving space (), which effectively improves an imaging quality of an object of interest being arrangeable at the object receiving space ().
