Perfusion analysis using DSC-MRI method
Minsterová, Alžběta ; Jiřík, Radovan (referee) ; Macíček, Ondřej (advisor)
This bachelor thesis deals with the DSC (Dynamic Susceptibility Contrast) method, which is one of the magnetic resonance imaging methods using a contrast agent. It describes the principle of the magnetic resonance imaging, other methods of MRI using the contrast agent are mentioned. It further contains the DSC-MRI method, common used sequences and the description of a procedure of an imaging by this method. This thesis also focuses on the implementation of a graphical application in MATLAB, which copes with the perfusion analysis and the visualization of perfusion maps.

X-ray imaging methods in veterinary medicine
KRONUSOVÁ, Kateřina
In modern times, the X-ray examination already has a permanent position in veterinary medicine when diagnosing various diseases. It is possible to use it to obtain detailed information about the shape, size, boundary, placement and even the internal structure of different organs. In order to get the largest amount of diagnostic information possible it is necessary that the X-ray examination be properly directed and executed with technological perfection. The results, i.e. the X-ray images, must be systematically, thoroughly and objectively analyzed and correctly incorporated into the overall clinical diagnosis. That{\crq}s why each X-ray worker must have a good knowledge of both medicinal and physical chemistry. The introduction of this thesis is dedicated to the general principles of a veterinary X-ray imaging such as exposure parameters or the geometry of a picture. Of course, the necessary protection against ionising radiation is also mentioned in this section. The central part of my work is composed of a summary and description of projections used in veterinary examining labs and clinics. I have focused primarily on dog and cat projections as they are the animals most frequently examined in veterinary clinics. Besides native projections, a certain part of my work is dedicated to examinations using contrast mediums. Another part is dedicated to the X-ray examination of exotic and small animals such as reptiles and birds. Throughout the paper, I have tried to use pictures as much as possible because I consider their example to be necessary in order to correctly understand the making of the projections. Since my goal was also to find out and analyse the utilisation rate of X-ray imaging methods in veterinary offices and clinics within the territory of the capital city of Prague, in the other part of my work there is elaborated information which was obtained with the help of questionnaires from veterinary work places and also information which was given to me by the State Office for Nuclear Safety.
