Název v původním jazyce

Enhancement of spatial resolution of roentgenographic methods

Popis výsledku v původním jazyce

The spatial resolution of X-ray micro radiography is usually the crucial parameter determining its performance and range of possible application. We demonstrate two methods for resolution enhancement (high- and low- magnification) based on the precise measurement of the PSF and the implementation of deconvolution. In the case of high geometrical magnification the X-ray source shape becomes the most important factor for PSF determination. A technique for the precise full 2-D measurement of X-ray spot size has been developed. The methods have been successfully demonstrated on the real radiograph images. The spatial resolution has been thus improved up to three fold. Another possibility for resolution enhancement is sub-pixel micro-shifting of the X-ray detector used. The successful demonstration of X-ray radiograph spatial resolution enhancement based on micro-shifting of the Medipix2 detector and measurement of its PSF is included.
