Research output: ThesisMaster's Thesis


The aim of this master thesis was to develop a test environment for an X-ray photon detection. To
accomplish this task, the current methods in medical imaging were ascertained, more specially the
common detector and their processing. A wide-ranging research gave details about some signal
specifications and further ideas for designing the circuit. The test environment included the controlled
signal generation, which reproduces the impact of photons on the detector followed by a signal. Next
up was to ensure, that the current signal is suitable for further processing, where a conversion into a
voltage signal should be guaranteed. Additionally, the developed circuit was then tested on its signal
generation property and was compared to another common method of short pulse generating, the
Switched Capacitances. The pulse generation properties included the signal shape, the pulse width,
the speed and the repeatability of the signal itself.
