MRI Acquisition and Preprocessing of Image Sequences for Clinical Perfusion Imaging
Krchňavý, Jan ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
This thesis describes the theory for static and dynamic magnetic-resonance imaging using contrast agents affecting T1 relaxation time. The available acquisition methods in the specified facility of Masaryk Oncological Institute in Brno are described. The sequences for subsequent experimental measurements are selected. The used phantoms are described. Acquisition protocol for measuring is described briefly and the evaluation method for the measured data is suggested. The best acquisition sequence and a method of measurements is chosen influenced by estimation of relaxation time T1, sensitivity and signal to noise ratio. Perfusion analysis is executed and perfusion parameters are calculated. The work was supported by the European Regional Development Fund and the State Budget of the Czech Republic (RECAMO, CZ.1.05/2.1.00/03.0101).

Design and construction of MR phatoms for MRI
Daňová, Ľudmila ; Odstrčilík, Jan (referee) ; Kudlička, Petr (advisor)
The object of the thesis is the design of the static phantom used in the MRI. It solves the generation of the pictures obtained from the magnetic resonance and its physical principles. The thesis focuses on two types of phantoms - dynamic and static, and especially on phantom used for the LCModel. There is also information about components that will be used for the detection of the spectrums of the selected metabolites.
