Available in PDF, EPUB and Kindle. Book excerpt: Bioelectric and Biomagnetic Fields: Theory and Applications in Electrocardiology begins with a general description of the development of extracellular bioelectric and biomagnetic fields and the methods used in their analysis and measurement. The most effective electrodynamic models and most modern approaches to topographical (synchronous multilead) measurements of the field are reviewed. The next section discusses the major approaches to analysis of the inverse problem with a detailed description of multipole technique applied to the bioelectric and biomagnetic fields measured on or near the body surface. Special emphasis is placed on the interrelationship between the electric and magnetic fields of the same bioelectric generator. The last section explains the new approaches to chronotopographical representation of the electrophysiological characteristics deduced from the parameters of the bioelectric generator. The text includes the most recent experimental protocols and results from studies in electro- and magnetocardiology and electro- and magnetoneurology.

Download or read book Methods for Processing and Visualising Body Surface Potential Maps written by Raymond Robert Bond and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The 12-lead Electrocardiogram (ECG) is a widely used diagnostic tool for assessing cardiac activity. Although its electrode configuration has been standardised since 1942, the number of electrodes and each of their anatomical positions are 'sub- optimal' in detecting cardiac pathologies such as Acute Myocardial Infarction (AMI). The Body Surface Potential Map (BSPM) is an alternative ECG technique that captures more cardiac information and has a higher sensitivity in detecting certain cardiac abnormalities. The BSPM, however, has not yet been accepted for routine clinical practice partly due to a lack of clinician-friendly tools for managing and visualising BSPM data. Following a review of ECG storage techniques, this Thesis presents an interoperable BSPM storage format that supports all BSPM variants. In a similar fashion, following a review of electrocardiographic visualisation, an intuitive Web-based BSPM visualisation system that exhibits a number of novel interactive features is presented in Chapter 5. Following this work, a number of peripheral studies were completed and presented in Chapter 6. This includes an advanced 12-lead ECG viewer. This viewer includes a visualisation feature for transforming the 12-lead ECG into an estimated BSPM. A knowledge representation framework called ecgRuleML was also designed. The ecgRuleML framework can be used to store, define and share rules that comprise diagnostic ECG criteria. Given the syntax of ecgRuleML is both human and machine- readable, it promotes the interoperability of ECG criteria amongst clinicians and heterogeneous ECG machines. Finally, a simulation tool called the Electrode Misplacement Simulator (EMS) was developed and described in Chapter 6. The EMS uses BSPM data to simulate the effects of electrode misplacement when recording a 12-lead ECG. The utility of the EMS for educating clinical physiologists was evaluated in a cross-sectional classroom study (refer to Chapter 7). Both the BSPM viewer and the EMS also underwent a usability evaluation. The closing Chapter outlines each hypothesis and provides a summary of contributions. The publications made during this PhD program have been listed in Appendix A.

This book was released on 1996-02-28 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This cross-disciplinary book documents the key research challenges in the mathematical sciences and physics that could enable the economical development of novel biomedical imaging devices. It is hoped that the infusion of new insights from mathematical scientists and physicists will accelerate progress in imaging. Incorporating input from dozens of biomedical researchers who described what they perceived as key open problems of imaging that are amenable to attack by mathematical scientists and physicists, this book introduces the frontiers of biomedical imaging, especially the imaging of dynamic physiological functions, to the educated nonspecialist. Ten imaging modalities are covered, from the well-established (e.g., CAT scanning, MRI) to the more speculative (e.g., electrical and magnetic source imaging). For each modality, mathematics and physics research challenges are identified and a short list of suggested reading offered. Two additional chapters offer visions of the next generation of surgical and interventional techniques and of image processing. A final chapter provides an overview of mathematical issues that cut across the various modalities.
