Book Description
Modern signal and image acquisition systems used in the field of cardiology acquire, analyze, and store data digitally. Surface electrocardiography, intra-cardiac electrogram recording, echocardiograms, x-ray, magnetic resonance imaging, and computed tomography are among the modalities in the cardiology field where signal processing is applied. Digital signal processing techniques allow us to automate many of the analyses that had previously been done manually with greater precision, accuracy and speed, as well as detect features and patterns in data that may be too subtle to observe by eye. As more cardiologists are becoming more reliant on such technology, a basic understanding of digital signals and the techniques used to extract information from these signals are required.

Multi-Spectral Signal and Its Processing
Author: Melinda
Publisher: Syiah Kuala University Press
ISBN: 6232645707
Category : Computers
Languages : en
Pages : 104
Book Description
An event that rises and falls in the peak value of the amplitude of a certain data as measured through the data acquisition process is known as fluctuation. Fluctuations usually occur because the data obtained during the acquisition process is mixed with noise. Therefore, an analytical approach is needed that can process signal fluctuations to identify the characteristics of a material. This study uses an object made of H2O material used as a measurement platform or footing. The other ingredients are H2O mixed with HCl and H2O mixed with NaOH. The initial processing approach is related to the material identification system using a capacitive sensor based on the Impedance Spectroscopy (SI) method. This study aims to develop a method for processing multi-frequency signal fluctuations resulting from data acquisition of Multi-Spectral Capacitive Sensors (MSCS). An approach to representing the observed fluctuations in data acquisition results is based on the statistical mean and standard deviation of the observed noise spectral in a large number of data sets. The results of signal fluctuations are divided into several types, namely: Mean Fluctuation (MF), High Fluctuation (HF), and High High-Fluctuation (HHF). Several approaches are taken for processing fluctuations, such as the data consistency process to see the stability of the data from the initial processing stage. Next is the stage of grouping data with several new approach methods. Another method that we use is the segmentation method which uses several filters that can divide some signals in the form of fluctuation patterns into several segments. From several approach methods that have been carried out, the results show that some of these methods can identify multi-spectral fluctuation patterns so that it will be easier for the next identification process.

Formation of Intracardiac Electrograms under Physiological and Pathological Conditions
Author: Keller, Matthias
Publisher: KIT Scientific Publishing
ISBN: 3731502283
Category : Technology & Engineering
Languages : en
Pages : 264
Book Description
This work presents methods to advance electrophysiological simulations of intracardiac electrograms (IEGM). An experimental setup is introduced, which combines electrical measurements of extracellular potentials with a method for optical acquisition of the transmembrane voltage in-vitro. Thereby, intracardiac electrograms can be recorded under defined conditions. Using experimental and clinical signals, detailed simulations of IEGMs are parametrized, which can support clinical diagnosis.

Book Description
There has been great progress and increase in demand for medical imaging. The aim of this book is to capture all major developments in all aspects of medical imaging. As such, this book consists of three major parts: medical physics which includes 3D reconstructions, image processing and segmentation in medical imaging, and medical imaging instruments and systems. As the field is very broad and growing exponentially, this book will cover major activities with chapters prepared by leaders in the field.This book takes a balanced approach in providing coverage of all major work done in the field, and thus provides readers a clear view of the frontier activities in the field. Other books may only focus on instrumentation, physics or computer algorithms. In contrast, this book contains all components so that the readers will obtain a full picture of the field. At the same time, readers can gain some deep insights into certain special topics such as 3D reconstruction and image enhancement software systems involving MRI, ultrasound, X-ray and other medical imaging modalities.

Computer Simulations and the Changing Face of Scientific Experimentation
Author: Eckhart Arnold
Publisher: Cambridge Scholars Publishing
ISBN: 1443849952
Category : Science
Languages : en
Pages : 260
Book Description
Computer simulations have become a central tool for scientific practice. Their use has replaced, in many cases, standard experimental procedures. This goes without mentioning cases where the target system is empirical but there are no techniques for direct manipulation of the system, such as astronomical observation. To these cases, computer simulations have proved to be of central importance. The question about their use and implementation, therefore, is not only a technical one but represents a challenge for the humanities as well. In this volume, scientists, historians, and philosophers join to examine computer simulations in scientific practice. One central aim of the volume is to provide a multi-perspective view on the topic. Therefore, the text includes philosophical studies on computer simulations, as well as case studies from simulation practice, and historical studies of the evolution of simulations as a research method. The theoretical studies in this book discuss the epistemological relation between simulations and experiments as well as the empirical or non-empirical status of data resulting from computer simulations. The role of simulations in current scientific practice is examined in the cases of astronomy, system biology, nanoscale research, and in the pharmaceutical industry. The historical perspective is brought in by examining the rise of supercomputing as well as the exploding number of published simulation studies in some scientific fields. The book concludes with critical reflections on the potential, limitations, and failures of computer simulations.
