Analysis and Application of Analog Electronic Circuits to Biomedical Instrumentation, Second Edition helps biomedical engineers understand the basic analog electronic circuits used for signal conditioning in biomedical instruments. It explains the function and design of signal conditioning systems using analog ICs—the circuits that enable ECG, EEG, EMG, ERG, tomographic images, biochemical spectrograms, and other crucial medical applications. This book demonstrates how op amps are the keystone of modern analog signal conditioning system design and illustrates how they can be used to build instrumentation amplifiers, active filters, and many other biomedical instrumentation systems and subsystems. It introduces the mathematical tools used to describe noise and its propagation through linear systems, and it looks at how signal-to-noise ratios can be improved by signal averaging and linear filtering. Features Analyzes the properties of photonic sensors and emitters and the circuits that power them Details the design of instrumentation amplifiers and medical isolation amplifiers Considers the modulation and demodulation of biomedical signals Examines analog power amplifiers, including power op amps and class D (switched) PAs Describes wireless patient monitoring, including Wi-Fi and Bluetooth communication protocols Explores RFID, GPS, and ultrasonic tags and the design of fractal antennas Addresses special analog electronic circuits and systems such as phase-sensitive rectifiers, phase detectors, and IC thermometers By explaining the "building blocks" of biomedical systems, the author illustrates the importance of signal conditioning systems in the devices that gather and monitor patients’ critical medical information.

Non-Invasive Instrumentation and Measurement in Medical Diagnosis, Second Edition discusses NIMD as a rapidly growing, interdisciplinary field. The contents within this second edition text is derived from Professor Robert B. Northrop’s experience teaching for over 35 years in the Biomedical Engineering Department at the University of Connecticut. The text focusses on the instruments and procedures which are used for non-invasive medical diagnosis and therapy, highlighting why NIMD is the preferred procedure, whenever possible, to avoid the risks and expenses associated with surgically opening the body surface. This second edition also covers a wide spectrum of NIMD topics including: x-ray bone densitometry by the DEXA method; tissue fluorescence spectroscopy; optical interferometric measurement of nanometer tissue displacements; laser Doppler velocimetry; pulse oximetry; and applications of Raman spectroscopy in detecting cancer, to name a few. This book is intended for use in an introductory classroom course on Non-Invasive Medical Instrumentation and Measurements taken by juniors, seniors, and graduate students in Biomedical Engineering. It will also serve as a reference book for medical students and other health professionals intrigued by the topic. Practicing physicians, nurses, physicists, and biophysicists interested in learning state of the art techniques in this critical field will also find this text valuable. Non-Invasive Instrumentation and Measurement in Medical Diagnosis, Second Edition concludes with an expansive index, bibliography, as well as a comprehensive glossary for future reference and reading.

The interdisciplinary field of biomedical engineering requires its practitioners to master not only engineering skills, but also a diversity of material in the biological sciences. This text helps biomedical engineers strengthen their skills in the common network of applied mathematics that ties together these diverse disciplines. Based on the author's 30 years of experience in teaching as well as his personal research on neurosensory systems, Signals and Systems Analysis in Biomedical Engineering provides a ready source of information on those specialized mathematical techniques most useful in describing and analyzing biomedical signals, including ECG, EEG, blood pressure, biochemical spectrograms, and tomographic images. Enriched with many examples that promote sound practical analysis, this book: Presents the traditional systems mathematics used to characterize linear time-invariant (LTI) systems and, given inputs, find their outputs Explains the relations between impulse response, real convolution, transfer functions and frequency response functions Reviews specialized mathematical techniques used to characterize and model nonlinear systems Introduces the basic mathematical tools used to describe noise and how it propagates through LTI and NLTI systems Describes how signal-to-noise ratio can be improved by signal averaging and linear and nonlinear filtering

Noninvasive medical diagnosis (NIMD) is as old as medical practice itself. From the earliest healers' observations of odors, skin color, and breath sounds to today's wealth of technologies, the basics remain the same and keep the role of NIMD essential to effective medical care. Noninvasive Instrumentation and Measurement in Medical Diagnosis is the first book dedicated to NIMD tools and techniques. Featuring emerging technologies along with traditional instruments, it describes how these non-invasive tools and techniques work and explores developments that will make NIMD simpler, more reliable, less expensive, and risk-free. Much of the material is descriptive, but the author includes rigorous mathematical analysis where appropriate. The treatment is readily accessible to readers with a background in basic algebra and ordinary differential equations, basic circuit theory, and concepts such as frequency response and transient response of linear systems. The rapid evolution of biomedical instrumentation has meant that books just five years old are already outdated. Whether used for an upper-level, biomedical engineering class or as a reference for medical students, healthcare professional, physicists, or physiologists, Noninvasive Instrumentation and Measurement in Medical Diagnosis stands alone in presenting the state of NIMD art and science.

Approaches such as the Transfer Function and the Fourier and the Laplace transforms are important tools for bioengineers that often considered borrowed from electrical engineering. This text allows bioengineering students and bioengineers the ability to foster a sense of ownership of these tools by providing them with a solid foundation in the concepts of linear systems analysis. Circuits, Signals and Systems for Bioengineers guides readers through the basic engineering concepts that underlie biological systems, medical devices, biocontrol, and biosignal analysis. Material important to their study and traditionally taught in an electrical engineering service course can now be embraced by bioengineers. Instructive illustrations and MATLAB routines and examples are provided throughout the book. Translates important electrical engineering tools such as Fourier Transform, Laplace Transform, analog modeling, systems modeling, and other linear systems analysis techniques for bioengineering students.
