Diffussion measurement by NMR
Vanko, Filip ; Gescheidtová, Eva (referee) ; Bartušek, Karel (advisor)
In Bachelor thesis is described the principle of MRI, the physical foundations of the phenomenon of magnetic resonance imaging, quantum and macroscopic model. Followed by a description of the mechanisms of relaxation of magnetic resonance phenomenon. In the following sections describes the basis of diffusion, each sequence for measuring diffusion NMR methods and the method of three measurements, which was used in experimental measurements. Last chapter deals with the practical. The results of measurements are evaluated in conclusion.

Errors of diffusion measurements for MRI
Kavan, Pavel ; Rampl, Ivan (referee) ; Bartušek, Karel (advisor)
The Bachelor’s thesis is, at it’s begining, focused on the imaging and diagnostic techniques based on principles of magnetic resonance imaging. Nowadays, nuclear magnetic resonance belongs to reputable examing methods of variable molecule matters. Especially, due to multiinterval spin-echo PFGSE methods. Further in this thesis is spin-echo pulse sequence simulated in the data processing computer program Matlab. Simulations influencing error measurement of b-factor and diffusion are performed. These simulations could help to prevent appearance of measurement errors at some other experiments.
