Measurement of dynamic quality of gradient magnetic fields
Kabrda, Miroslav ; Kubásek, Radek (referee) ; Bartušek, Karel (advisor)
In the first chapter of bachelor thesis I focused on description the tomograph construction. The next chapter deals with the measurement of gradient magnetic fields, using methods based on instantaneous frequency. The thesis describes: the IF method, the IFSE method ( the method of measuring the instantaneous frequency of the spin echo), the IFSES method (the instantaneous frequency measurement method for a series of spins) and the method of Gradient decay measurement in NMR tomography. Each method describes the basic principles of the measurement, the excitation pulse sequence, obtainment of instantaneous frequency and the method of evaluation of the obtained signal. This bachelor thesis includes experimental measurements using the method of Gradient decay measurement in NMR tomography. The experimental data obtained are given and evaluated in the last chapter at the end of the thesis.

Propoasl of a laboratory workplace for verifying the NMR principle
Kropáč, Ondřej ; Bartušek, Karel (referee) ; Gescheidtová, Eva (advisor)
This project deals with the design of a laboratory workplace for verifying the basic principles of nuclear magnetic resonance. In the theoretical part of the project a basic knowledge of nuclear magnetic resonance are summarized, and the process of evaluation the results obtained from NMR signal is described. The proposed part of work is aimed at a design of a NMR spectrometer block diagram and a proposal of a resonant circuit and NMR probes. In the practical part the technologic process of the probes production and their settings are specified. The results of the designed probes comparison are in the last, measuring, part.
