Description
| - This work devotes to the optimization of digital X ray transmission radiography for the observation of time dependent processes using a single X-ray photon counting pixel device. The maximization of frame rate of acquired roentgenograms is crucial for this purpose. The influence of the X ray tube voltage on exposure time, which is necessary for sufficient quality of roentgenograms, was investigated. Roentgenograms are distorted due to non uniform pixel detection efficiency across the X ray detector. Such distortion can be successfully eliminated by the proposed “Direct thickness calibration method” regardless of X ray beam hardening, which is due to the variation of inspected body absorption.

- Tato práce je věnována optimalizaci sledování časově závislých procesů metodou rentgenovské radiografie pomocí pixelových detektorů jednotlivých fotonů. Maximalizace četnosti snímků je zásadním problémem této oblasti. Byl studován vliv pracovního bodu rentgenky (napětí) na nutné exposiční časy. Rentgenogramy jsou poškozovány díky nestejné citlivosti jednotlivých pixelů snímače. Toto poškození stejně jako vliv efktu tvrdnutí svazku lze úspěšně odstranit metodou přímé kalibrace tloušťky která je (cs)
