Methods of weighting the magnetic resonance signal
Filla, David ; Kubásek, Radek (referee) ; Hadinec, Michal (advisor)
The objective of this project is introduction to the fundamental principle of magnetic resonance and to the basic measuring methods used in MR. There is also described how to set parameters of pulse sequences in different measuring methods to obtain an image weighted by relaxation T1, relaxation T2, diffusion and eventually proton density. In the experimental part, we have measured images of three samples (tomato, pepper and mandarin) by four methods (SE, GE, IRSE and IRFSE). For obtained measured images we have proceed phase correction, created T2 and T2* maps. Then we consider the images obtained in terms of quality and compare with each other.

MR imaging of somatic embryos
Chovanec, Ján ; Kubásek, Radek (referee) ; Bartušek, Karel (advisor)
The aim of this bachelor thesis is measuring of tissue cultures of spruce MR imaging methods. Was measured set of samples, where was found contain of cluster in each cuts. To obtain the image, the magnetic resonance was used, specifically spin echo sequence. Method called spin echo is based on two pulses 90° and 180°. Selected method from the beginning of the work is than used to measure the diffusion and processing of cultures. In last part the work is devoted to data processing in Matlab and Marevisi.
