This book examines non-invasive, electrical-based methods for disease diagnosis and assessment of heart function. In particular, a formalized signal model is proposed since this offers several advantages over methods that rely on measured data alone. By using a formalized representation, the parameters of the signal model can be easily manipulated and/or modified, thus providing mechanisms that allow researchers to reproduce and control such signals. In addition, having such a formalized signal model makes it possible to develop computer tools that can be used for manipulating and understanding how signal changes result from various heart conditions, as well as for generating input signals for experimenting with and evaluating the performance of e.g. signal extraction methods. The work focuses on bioelectrical information, particularly electrical bio-impedance (EBI). Once the EBI has been measured, the corresponding signals have to be modelled for analysis. This requires a structured approach in order to move from real measured data to the model of the corresponding signals. This book proposes a generic framework for this procedure. It can be used as a guide for modelling impedance cardiography (ICG) and impedance respirography (IRG) signals, as well as for developing the corresponding bio-impedance signal simulator (BISS).

Diseases once believed to be confined to the tropics, such as parasitic, mycobacterial, fungal, bacterial, and viral infections are still a major cause of mortality and moribidity in the tropics, yet can affect the developed world in an era of increased global travel and migration. Neuroimaging technique developments over the last several decades have helped clinicians better understand and diagnose these conditions. Experts from tropical countries share their experiences regarding tropical disorders, some of which are rare in the western world, but possible to appear in patients and not readily recognized by specialists not familiar with these diseases.

Topics in this issue include: Relevance of neuroimaging in the diagnosis and management of tropical neurologic disorders; Pathology of Tropical Diseases; Viral Infections of the Central Nervous System; Central Nervous System Tuberculosis; Parasitic diseases of nervous system; Neuroimaging in Post-infectious Demyelination and Nutritional Disorders of the Central Nervous System; CNS Fungal Infections in the Tropics; Neuroimaging Epilepsy in the Tropics; Neuroimaging in Cranio-Vertebral Anomalies as seen in Tropics; Vascular Brain Pathologies; Neurobrucellosis; Hirayama Disease; Transverse Myelitis; and Pyomyositis.

Since the early 20th century, medical imaging has been dominated by monochrome imaging modalities such as x-ray, computed tomography, ultrasound, and magnetic resonance imaging. As a result, color information has been overlooked in medical image analysis applications. Recently, various medical imaging modalities that involve color information have been introduced. These include cervicography, dermoscopy, fundus photography, gastrointestinal endoscopy, microscopy, and wound photography. However, in comparison to monochrome images, the analysis of color images is a relatively unexplored area. The multivariate nature of color image data presents new challenges for researchers and practitioners as the numerous methods developed for monochrome images are often not directly applicable to multichannel images. The goal of this volume is to summarize the state-of-the-art in the utilization of color information in medical image analysis.

In the later stages of gestation, fetal functions undergo increasing change and development, preparing the fetus for the transition to its postnatal environment. Rapid maturation is witnessed in breathing, swallowing, sensory functions, sleep, and many other processes, with corresponding behavioral changes. By 35 to 40 weeks of gestation, fetuses are capable of living ex utero without support, but it is increasingly appreciated that even infants born at between 35 and 36 weeks can suffer long-term consequences. This book, which complements the author's previous volume on development of normal fetal movements during the first 25 weeks of gestation, discusses in detail the full range of behavioral phenomena observed during the final 15 weeks of gestation, with careful analysis of their mutual relationships. A key feature is the outstanding photographic material, difficult to obtain at this late stage, and the instructive graphs that are also included. The information provided will alert clinicians to deviations from the norm and to physiologic phenomena that can turn pathologic in infants born prematurely.

Traditional research methodologies in the human respiratory system have always been challenging due to their invasive nature.
