Monoclimate Incubation Chamber - Temperature Control
Kovářová, Anežka ; Pánek, Libor (referee) ; Sekora, Jiří (advisor)
This bachelor thesis deals with the design of the monoclimate incubator chamber for in vitro cell cultivation and cell observing under the confocal microscope. It is based on requirements and parameters set by the biophysics laboratory of FEEC BUT. In vitro cell cultivation is explained, temperature and humidity sensors are described here. The main part is dedicated to the theoretical design and realization of the tempered monoclimate chamber with temperature controlling and humidity control using a microcontroller.

Comparison and assessment of single-echo and multi-echo BOLD fMRI acquisition
Kovářová, Anežka ; Jiřík, Radovan (referee) ; Mikl, Michal (advisor)
This master’s thesis deals with functional magnetic resonance and monitoring of the effect of acquisition acceleration methods on the quality of functional images and observed BOLD signal. The basic principles of magnetic resonance imaging, the explanation of the specifics of functional magnetic resonance and the formation and scanning of BOLD signal are described here. Subsequently, there is the definition of fMRI experiment and description of sequences used for fMRI, focusing on aquisition acceleration techniques. The influence of sequence parameters on image quality and the data processing methods are explained aftewards. The practical part describes the parameters of used sequences, the acquisition procedure and the task for the subject during aquisition. Data from 26 healthy volunteers were obtained and analyzed afterwards. Based on this, the differencesbetween the different sequence variants were evaluated and the initial assumption that the multi-echo acquisition yields better results with faster measurements than single-echo was confirmed.
