Challenges in Optimal Bandwidth for Medical Image Transfer
Schindler, Vladimír ; Šimák, Boris (referee) ; Šárek, Milan (referee) ; Dostál, Otto (advisor)
This dissertation thesis is focused on the optimization of bandwidth parameters for the transport of medical image data between medical devices and remote data storage. As real and fully functional structure, which will be analyzed in this work. It was selected system MeDiMed (Metropolitan Digital Imaging System in Medicine). The thesis examines the operation of the small health organizations and their modalities, which use this system for remote data archiving. Traffic analysis is then statistically processed. The thesis also deals with the analysis of increasing the security during accessing health system, and assesses its impact on transmitted data. The effect of setting the transmission parameters and the most widely used types of ciphers on the transfer speed is also compared.

Neuroinformatics and sharing data from medical imaging systems
Klimek, Martin ; Kubásek, Miroslav (referee) ; Provazník, Ivo (advisor)
The presented master's thesis deals with the issue of storing and sharing data from medical imaging systems. This thesis, inter alia, consists of organizational and informatics aspects of medical imaging systems data in multicentric studies containing MRI brain images. This thesis also includes technical design of a web-based application for image data sharing including a web interface suitable for manipulation with the image data stored in a database.

The Economic Potential of Existing eHealth Systems in the Czech Republic
Bruthans, Jan ; Ševčík, Miroslav (advisor) ; Kotýnková, Magdalena (referee) ; Večeř, Jan (referee)
The purpose of this dissertation is to explore the contemporary area of information technologies employed in health care (eHealth). Focusing on the systems already employed in the Czech Republic, it aims to analyse them, to quantify expenditures of their introduction and maximum benefits derived from these, as well as to evaluate their real current profit. Out of the three existing national systems, this dissertation concentrates on the two only (eRecept, ePACS), as it became impossible to evaluate the third -- IZIP system due to scarcity of the relevant information available. In the field of expenditures not only generally published numbers are taken into consideration, but this dissertation also evaluates the expenditures of other subjects involved (IT systems producers, health care providers, etc.). As the first dissertation in the Czech Republic it quantifies benefits derived from the existing eHealth systems and unlike foreign theses it greatly emphasizes just the expenditures of other subjects involved. Included in this dissertation is also the evaluation of achievements of the eHealth systems in the Czech Republic complete with supposed grounds for this situation. This dissertation also recommends courses of action for contractors of these systems to ensure future basis for more economical and successful eHealth systems. These recommendations are mainly based on analysis of development of the existing national eHealth systems. For the complex evaluation of the costs, maximum of possible and real benefit of the individual eHealth systems the research approach adopted in this dissertation includes descriptive method and SWOT analysis, extrapolation and abstraction, comparative and factor analysis.

PACS (Picture archiving and communicating system), confrontation advantages and disadvantages two systems
ČECHOVÁ, Petra
The system PACS ( Picture archiving and communicating system) was developed in medical institutions because of all the time increasing requirements on images elaborated at digital imaging machines. The thesis deals with the basic definition of Picture archiving and communication system (PACS), explains basic definitions and importance of contemporary valid definition for DICOM (Digital Imaging and Communications in Medicine). It further deals with possibilities offered by PACS, especially its linking with existing hospital information system. There are mentioned advantages, disadvantages, risks and usage of this system in medicine. The aim of my thesis is comparison of two communications systems for archiving and image transmission. The research processed in Teaching Hospital of Saint Anna in Brno and in Masaryk Oncology Institution thanks to description of system structure and sent questionnaires on this topic.

Impact of digital imaging on practical work of radiographer
MAREK, David
The submitted bachelor{\crq}s paper deals with the impact of digital imaging on the practical activity of a radiological assistant. In 2006, I participated in a professional seminar held by the AURA-GROUP company, which focused on digitalization of modalities in the health service. This topic seemed to be so interesting for me that I decided to find out what their experience were and what the comparison of the analogue and digital imaging would be like from the point of view of assistants working in practice and to find out more about requirements concerning a radiological assistant{\crq}s work both under the analogue and under the digital operation. In the theoretical section, the principle of X-rays is provided together with a small excursion into the history and the method of analogue and digital imaging and current methods of archiving as well. In this section, the current state of radiology is surveyed and the principles of the individual methods, their advantages and disadvantages together with future prospective are described here as well. In the practical section, I decided to verify the hypothesis that the digital imaging is more valuable in practice that the analogue one. Within the framework of quantitative methodology, the method of fact-finding through questionnaire was used. This questionnaire was presented to employees of radiological departments and the results were subsequently statistically processed and evaluated. The research sample was set up from employees working in the radiological departments in the hospitals in České Budějovice and Český Krumlov. For the purposes of this research, I made no difference as far as the individual age categories or educational background or any other criteria are concerned. This means that this selection was not limited in any way and it has, in my opinion, sufficient support both from the theory and practice and thus it has a sufficient testifying value with respect to the knowledge and experience of the radiological assistants subject to the research. The results of this work confirmed the respective hypothesis and it was demonstrated that digitalization has positive impact on practical activity of a radiological assistant for the purpose of post-processing adjustments, X-ray images archiving using the PACS system, and the fact that there is no need of the so-called wet process is particularly beneficial as well. In the summary, we should also see economic advantages, as they are one of The most important criteria for development of new methods of activities in the field of health care at the present time. The fact that the digital method of imaging saves costs relating to films, chemical substances, archiving capacities (rooms and staff) brings substantial savings, which may be utilized for example for the purchase of technologically advanced equipment.

An analysis of the use of digitalization in the department of radiology
Potančok, Martin ; Kunstová, Renáta (advisor) ; Plšková, Lenka (referee)
This bachelor thesis is focused on the digitalization of medical records in the departments of radiology in hospitals. The aim of this thesis is to introduce the process of the digitalization of medical records in the departments of radiology, analyze the effectiveness of changes and make recommendations for non digitalized departments. The introductory section deals with the legislative and technological background of the digitizing. The second part is focused on a real case study of the implementation process. It is a modernisation of the whole department of radiology in a medium-size district hospital. The third, and most important, section contains the analysis of the implementation. There is also a comparison with the analogue option. The last section consists of recommendations for the selection process and the implementation of new technologies for non-digitalized departments of radiology for both the smallest and medium sizes.
