Measurement of Dialyser-Membrane Diffusion Coefficient
Kašák, Pavel ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
This thesis focuses on the measurement of diffusion coefficient of dialysis membrane. The first part describes possibilities of membrane modelling. Basic models, which allow us to determine the basic characteristics of dialysis membranes like permeability and diffusion coefficient, are described. Next chapter deals with basic types and properties of membranes. The main part focuses on making the experimental installation, which is used to simulate permeance of contrast agent, used in DCE-MRI, through dialysis membrane. The last theoretical chapter describes calculations used to estimate diffusion coefficient. Practical part of this thesis uses a designed experimental installation for estimation of diffusion coefficient for two contrast agents Gadovist® and Multihance®.

MRI Acquisition of Image Sequences for Preclinical Perfusion Imaging
Krátká, Lucie ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
The task of this thesis is to study methods for the acquisition perfusní imaging based on dynamic MR imaging with T1 contrast. It describes methods of measurement of T1 relaxation time and the possibility of evaluating the results. It further describes the phantoms and their use. And it is here mentioned for the dynamic acquisition protocol perfusní imaging. There is also described in detail created a program for automatic control of the NMR system. In the experimental measurements are performed on static and dynamic phantom, are also evaluated perfusion parameters from the Flash sequence.

Image Formats
Wolanský, David ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
The thesis deals with a detailed analysis of the GIF file format. It is divided into two basic parts, theoretical and practical. The theoretical part includes a thorough analysis of the internal file structure, i.e. the description of the individual block types, of which the file consists. Each block-type characteristic includes properties and a detailed description of its individual items. This part also includes a brief description of the most common compression methods applied in the field of image compression. The practical part includes the design and implementation of an edutainment application for synoptic viewing of the internal structure for a chosen GIF file and its parameters. The implementation of the application covers algorithms for selection of individual block types and realization of a graphical user interface.

MRI Acquisition and Preprocessing of Image Sequences for Clinical Perfusion Imaging
Krchňavý, Jan ; Bartoš, Michal (referee) ; Jiřík, Radovan (advisor)
This thesis describes the theory for static and dynamic magnetic-resonance imaging using contrast agents affecting T1 relaxation time. The available acquisition methods in the specified facility of Masaryk Oncological Institute in Brno are described. The sequences for subsequent experimental measurements are selected. The used phantoms are described. Acquisition protocol for measuring is described briefly and the evaluation method for the measured data is suggested. The best acquisition sequence and a method of measurements is chosen influenced by estimation of relaxation time T1, sensitivity and signal to noise ratio. Perfusion analysis is executed and perfusion parameters are calculated. The work was supported by the European Regional Development Fund and the State Budget of the Czech Republic (RECAMO, CZ.1.05/2.1.00/03.0101).

Belt conveyor
Bartoš, Michal ; Pokorný, Přemysl (referee) ; Jonák, Martin (advisor)
This bachelor thesis deals with construction design of belt conveyor for transporting waste paper by an angle of 45°, the required delivery capacity 100 kg/h, belt width of 300 mm and 6500 mm length of the conveyor. The thesis includes a search report and function calculation of belt conveyor according to ČSN ISO 5048. There are designed individual parameters and design features, together with the drive and tensioning device. It is also drawn strength calculation of the shell axis and driven drum and controlled tensioning devices. The work also includes drawing documentation.
