Compression and Quality Assessment of ECG Signals
Němcová, Andrea ; Tkacz,, Professor Ewaryst (referee) ; Kudrna,, Petr (referee) ; Vítek, Martin (advisor)
Ztrátová komprese signálů EKG je užitečná a v současnosti stále se rozvíjející oblast. Stále se vyvíjí nové a nové kompresní algoritmy. V této oblasti ale chybí standardy pro hodnocení kvality signálu po kompresi. Existuje tedy sice mnoho různých kompresních algoritmů, které ale buď nelze objektivně porovnat vůbec, nebo jen zhruba. V oblasti komprese navíc nikde není popsáno, zda mají na výkon kompresních algoritmů vliv patologie, popřípadě jaký. Tato dizertační práce poskytuje přehled všech nalezených metod pro hodnocení kvality signálů EKG po kompresi. Navíc bylo vytvořeno 10 nových metod. V rámci práce byla provedena analýza všech těchto metod a na základě jejích výsledků bylo doporučeno 12 metod vhodných pro hodnocení kvality signálu EKG po kompresi. Také je zde představen nový kompresní algoritmus „Single-Cycle Fractal-Based (SCyF)“. Algoritmus SCyF je inspirován metodou založenou na fraktálech a využívá jednoho cyklu signálu EKG jako domény. Algoritmus SCyF byl testován na čtyřech různých databázích, přičemž kvalita signálů po kompresi byla vyhodnocena 12 doporučenými metodami. Výsledky byly porovnány s velmi populárním kompresním algoritmem založeným na vlnkové transformaci, který využívá metodu „Set Partitioning in Hierarchical Trees (SPIHT)“. Postup testování zároveň slouží jako příklad, jak by měl vypadat standard hodnocení výkonu kompresních algoritmů. Dále bylo statisticky prokázáno, že existuje rozdíl mezi kompresí fyziologických a patologických signálů. Patologické signály byly komprimovány s nižší efektivitou a kvalitou než signály fyziologické.

Modern Technologies in Medicine and Law
Konečná, Klaudie ; Zvára, Michael (referee)
Modern Technologies in Medicine and Law Abstract This thesis deals with the application of modern technologies in medicine from the perspective of law. The primary aim of this work is to analyse the given provisions of the Civil Code, Act on Health Services and Act on Medical Devices, and also to determine whether the current legislation represents a suitable legal framework able to respond to the implementation of modern technology in the healthcare sector. In connection with this analysis, author presents possibilities of legislative changes that would respond to these modern technologies. The work inter alia deals with the question of whether the use of some of these technologies within the provision of healthcare services can be considered compliant with the principle of lege artis. In the first chapter, the reader is introduced to the topic of the thesis. This chapter defines the basic terms and presents an overview of the legislation related to the chosen topic. The second chapter represents a main part of the thesis, where author deals with the topic of artificial intelligence. In this chapter, the reader is acquainted with the term of artificial intelligence and the definition of its legal status. Subsequently, author evaluates whether the current legislation constitutes appropriate legal frameworks...

Application for heart rate estimation using smartphone
Šara, Kryštof ; Vítek, Martin (referee) ; Němcová, Andrea (advisor)
This student work deals with the issue of heart biosignals, their processing, the possibility of their acquisition using conventional and smart devices, and the regulation of mobile devices in healthcare. The work also includes the design of a mobile application, which can be used to a quick estimation of the human heart rate (HR). The optimized functional application algorithm was tested on a sample of independent subjects and a mean deviation of 0.74 beats per minute (BPM), relative to the ECG reference record, was reached.

Accelerometer-based quality estimation and segmentation of ECG signal and compression of high-quality segments
Opravilová, Kamila ; Smital, Lukáš (referee) ; Němcová, Andrea (advisor)
This diploma thesis is devoted to segmentation of ECG signal based on its quality and compression of quality segments suitable for diagnostics (in telemedicine). A completely new approach is to use accelerometer data to estimate ECG signal quality. This is possible thanks to the Bittium Faros mobile recorder. It records both the ECG signal motion – accelerometric data. A total of 34 features were extracted from accelerometric data. Using these features the predictive model was taught to classify the ECG signal into 3 quality groups according to the level of noise. Quality segments were compressed. The wavelet transform in combination with high-frequency bands zeroing and length encoding was used as a compression method.

Application of telemedicine principles and technologies in the field of life insurance
Stašek, Filip ; Pavlíček, Antonín (advisor) ; Bach, Štěpán (referee)
The aim of diploma thesis is description and application of new product in life insurance area. This product is based on insured body parameters and physical activity monitoring with the assistance of wearables. Based on analysis of the data obtained by the insurance company, it can be setting appropriate and fair price of life insurance. Introduction describes principle of Internet of Things, which idea is reflected in next part described eHealth and telemedicine industries, where will be defined the possibilities of use information and communication technologies in these industries. One from the technologies using in these industries are already mentioned wearables, which can be used into the basic monitoring of individuals health condition. Except of health services is possible use these wearables in insurance industry too, where can monitor physical activity and selected body parameters of individuals and motivate them to exercise and healthy lifestyle in form of insurance discounts. The thesis points to current situation of using these devices at the local as well as global insurance market and possible principle of monitoring and analysis body parameters and lifestyle at Czech insurance market in the form of a new life insurance product.

Information and Communication Technologies in Social and Healthcare Services
Jakoubek, Rostislav ; Havrdová, Zuzana (advisor) ; Lejsal, Matěj (referee)
The thesis discusses how information and communication technologies (ICT or IT), nowadays transforms the form of health and social services. The specific arguments and social events are described, that leads today's health and social services closer to the use of ICT, influence and changes it. The work describes the latest trends linking ICT and social and health services in the areas of e-health, telemedicine, mobile health and assistive technologies. Specific tools and equipment and their practical use are presented. The practical part focuses on the introduction of specific- gadgets tablet care in caring for the elderly. Through direct interviews with caregivers and seniors is investigated how new technology is perceived by caregivers and seniors, how new technology equipment to care are introduced, and what positive and negative impact are the ICT has for facilities and the elderly. Key words assistive technology; eHealth; mHealth; patient engagement; population ageing; senior activation; senior care; telemedicine; touch tablets
