Fluorescence imaging techniques in multimodal holographic microscope
Vašíček, David ; Procházková, Jana (referee) ; Čolláková, Jana (advisor)
The diploma thesis deals with the registration of images taken with the multimodal holographic microscope (MHM). The summary covers the fluorescent and holographic microscopy, and the multimodal holographic microscope combining both these microscopy types. Every pair of the images needs to be aligned in order to gain new information by combining both image types. The thesis contains an algorithm that registers images by phase correlation as well as a process created in MATLAB in accordance with the algorithm. The most important procedure parameters’ influence on the registration success is described and the results are annotated.

Cell tracking in images from holographic microscope
Vičar, Tomáš ; Odstrčilík, Jan (referee) ; Kolář, Radim (advisor)
This thesis focuses on cell tracking in image sequences acquired using a multimodal holographic microscope (MHM). The principles of holographic microscopy are described together with the application in cells acquisition. The main part of the thesis describes a complete approach for segmentation and tracking of single cells in acquired in long-term sequences. The approach is designed based on parametric active contour models with specific modifications to achieve reasonable precision and robustness. The implemented method is described in detail, including the evaluation and demonstration of results.

Observation of external environment influence on living cells with holographic microscope
Kovářová, Klára ; Tolde,, Ondřej (referee) ; Křížová, Aneta (advisor)
Subject of this master's thesis is the observation of influence of external environment on the living cells with the use of multimodal holographic microscope. The theoretical part is summarising the development of the holographic microscopy at IPE FME BUT. The theoretical part also describes multimodal holographic microscope, which allows non-invasive observing of living cells. The thesis also covers construction of the microscope, basic working instructions and the hologram processing method. The main subject of the thesis is the research on the topic of chemotaxis and osmotic processes in the cells. Experiments were designed for the purpose of this thesis to cover topics mentioned above. The experimental part of the thesis deals with cultivation of the cells, preparation of the sample and observation chambers and processing of the data. This part later focuses directly on the laboratory measurements. In all experiments, cells K2 (full name LW13K2) were observed.

Cell Tracking in Multimodal Holographic Microscope Using Transmission Mode
Blašťáková, Lucia ; Křížová, Aneta (referee) ; Štrbková, Lenka (advisor)
This thesis is focused on the monitoring of cell dynamics in multimodal holographic microscope using transmission mode. The goal of this experiment is a quantitative description of the epithelial-mesenchymal transition of cancer cells NMuMG. The introduction briefly describes a history of interference microscopy and its applications, design of multimodal holographic microscope Q-Phase and work with the program used for data processing. Next follows a brief description of parameters that were selected to quantify the epithelial-mesenchymal transition. In conclusion, all results from the observation of epithelial-mesenchymal transition were summarized.

Observation of Influence of Thin Layers on Cell Behaviour by Multimodal Holographic Microscope
Vengh, Martin ; Křížová, Aneta (referee) ; Štrbková, Lenka (advisor)
Surface treatment of materials for the cell-surface interaction and imitating intrinsic environment of cells is still subject of matter for their potentional usage in the bioengineering. One of the options to modify the surface of material is exhibiting them to effects of plasma of electrical discharge in steam of cyclopropylamine. In this type of plasma, the low pressure plasma polymerization takes place, which creates thin amine-rich layer. There is an assumption that this type of layer is appropriate for cell adhesion and proliferation. As a superior technique for a label-free monitoring of the cell-surface interaction, multimodal holographic microscope (MHM) Q-Phase was exploited to determine the biocompatibility of materials. MHM enables observation in quantitative phase imaging, where the phase is directly proportional to the cell dry mass. This gives opportunity to define various features able to determine the biocompatibility of materials. According to the results amine-rich films enhanced the conditions for the cell adhesion and proliferation.
