Simulation of the CT X-ray Detectors
Koutek, Petr ; Walek, Petr (referee) ; Drastich, Aleš (advisor)
The bachelor thesis deals with the basic properties of the detectors used in X-ray CT, and their influence on the choice of acquisition parameters. The theoretical part summarizes the general issues of projection reconstruction view and basic characteristics of the detectors. In the practical part is created simulator which simulate the effect of deacy time, afterglow and the light output.

CT X-ray quantitative evaluation
Novotný, Lukáš ; Malínský, Miloš (referee) ; Drastich, Aleš (advisor)
X-Ray Computed Tomography is irreplaceable medical imaging system. Quantitative evaluation is day to day routine used for clean run of this imaging system. The master’s thesis is focused on quantitative evaluation of first and third generation X-Ray CT. First of all is about subjective and objective evaluation of space and energetic resolution. Space resolution is evaluated in space and frequency domain. Energetic resolution is represent by low contrast resolution method. Application “Kvantitativní hodnocení kvality CT RTG zobrazení” created for this thesis is used for creation of reconstruction image and quantitative evaluation. This application was created with consideration of its usage in subjects about image processing. The master’s thesis contains results of quantitative evaluation X-Ray CT created with this application and proposal of lab work.
