Quantification of Biophysical Parameters in Medical Imaging

by Ingolf Sack Tobias Schaeffter

This book provides a selection of essential knowledge on the image-based quantification of biophysical parameters for the purpose of clinical diagnosis. The authors regard clinical imaging scanners as physical measurement systems capable of quantifying intrinsic parameters for depiction of the constitution and biophysical properties of in vivo tissue. On the one hand, this approach supports the development of new methods of imaging highly reproducible, system-independent, and quantitative biomarkers, and these methods receive detailed attention in the book. On the other hand, the reader will also gain a deeper understanding of how physical tissue properties interact with the generation of signals in medical imaging, opening new windows on the intricate and fascinating relationship between the structure and function of living tissues. The book will be of interest to all who recognize the limitations of basing clinical diagnosis primarily on visual inspection of images and who wish to learn more about the diagnostic potential of quantitative and biophysics-based medical imaging markers and the challenges that the paucity of such markers poses for next-generation imaging technologies.

Quantification of Contrast Kinetics in Clinical Imaging (SpringerBriefs in Applied Sciences and Technology)

by Massimo Mischi Simona Turco Osama I. Soliman Folkert J. ten Cate Hessel Wijkstra Ivo Schoots

This book provides a comprehensive survey of the pharmacokinetic models used for the quantitative interpretation of contrast-enhanced imaging. It discusses all the available imaging technologies and the problems related to the calibration of the imaging system and accuracy of the estimated physiological parameters. Enhancing imaging modalities using contrast agents has opened up new opportunities for going beyond morphological information and enabling minimally invasive assessment of tissue and organ functionality down to the molecular level. In combination with mathematical modeling of the contrast agent kinetics, contrast- enhanced imaging has the potential to provide clinically valuable additional information by estimating quantitative physiological parameters. The book presents the broad spectrum of diagnostic possibilities provided by quantitative contrast-enhanced imaging, with a particular focus on cardiology and oncology, as well as novel developments in the area of quantitative molecular imaging along with their potential clinical applications. Given the variety of available techniques, the choice of the appropriate imaging modality and the most suitable pharmacokinetic model is often challenging. As such, the book provides a valuable technical guide for researchers, clinical scientists, and experts in the field who wish to better understand and properly apply tracer-kinetic modeling for quantitative contrast-enhanced imaging.

Quantified Eco-Efficiency: An Introduction with Applications (Eco-Efficiency in Industry and Science #22)

by Gjalt Huppes Masanobu Ishikawa

A central asset of eco-efficiency analysis is that it does not depend on a specific evaluation of environmental impacts against economic effects. Several evaluation methods may be used, including those based on willingness-to-pay, panel procedures, and public statements on policy goals. This volume covers all aspects of eco-efficiency analysis and offers a global perspective on the subject.

Quantified Societal Risk and Policy Making (Risk, Governance and Society #12)

by P. J. M.Stallen R. E. Jorissen

Quantified Societal Risk and Policy Making is the result of an international workshop on societal risk organized by the Dutch Ministry for Transport, Public Works and Water Management with additional financial support from the Directorate for Transportation (DG VII) of the European Union. Managing risks, whether there is a strong man-made or natural component, basically means assessing alternative options under uncertainty. The possibility of multiple fatalities is one of the factors that can vary between options. This volume is concerned with one particular type of risk - the risk of death of a number of people in one accident - and with one particular tool - probabilistic risk analysis - as they are developing in various domains of society nowadays. Generally, this risk is labelled societal risk. This book shows how such comparisons are shaped at present in various hazard domains, such as: flood protection location and physical planning of industry transportation of chemicals, and prevention of aircraft accidents. It examines how to represent aggregate risks from major hazards in ways that can be handled by policy-makers. The purpose of the book is to increase the awareness of societal risk, disseminate available knowledge of existing approaches, and exchange information on applications from various domains. Quantified Societal Risk and Policy Making should be of interest to all those professionally concerned with defining the optimal separation between hazardous activities and equally desirable developments nearby.

Quantifying Aesthetics of Visual Design Applied to Automatic Design (Springer Theses)

by Ali Jahanian

In this thesis, the author makes several contributions to the study of design of graphical materials. The thesis begins with a review of the relationship between design and aesthetics, and the use of mathematical models to capture this relationship. Then, a novel method for linking linguistic concepts to colors using the Latent Dirichlet Allocation Dual Topic Model is proposed. Next, the thesis studies the relationship between aesthetics and spatial layout by formalizing the notion of visual balance. Applying principles of salience and Gaussian mixture models over a body of about 120,000 aesthetically rated professional photographs, the author provides confirmation of Arnhem's theory about spatial layout. The thesis concludes with a description of tools to support automatically generating personalized design.

Quantifying and Exploring the Gap Between FPGAs and ASICs

by Ian Kuon Jonathan Rose

Field-programmable gate arrays (FPGAs), which are pre-fabricated, programmable digital integrated circuits (ICs), provide easy access to state-of-the-art integrated circuit process technology, and in doing so, democratize this technology of our time. This book is about comparing the qualities of FPGA – their speed performance, area and power consumption, against custom-fabricated ICs, and exploring ways of mitigating their de ciencies. This work began as a question that many have asked, and few had the resources to answer – how much worse is an FPGA compared to a custom-designed chip? As we dealt with that question, we found that it was far more dif cult to answer than we anticipated, but that the results were rich basic insights on fundamental understandings of FPGA architecture. It also encouraged us to nd ways to leverage those insights to seek ways to make FPGA technology better, which is what the second half of the book is about. While the question “How much worse is an FPGA than an ASIC?” has been a constant sub-theme of all research on FPGAs, it was posed most directly, some time around May 2004, by Professor Abbas El Gamal from Stanford University to us – he was working on a 3D FPGA, and was wondering if any real measurements had been made in this kind of comparison. Shortly thereafter we took it up and tried to answer in a serious way.

Quantifying the Value of RFID and the EPCglobal Architecture Framework in Logistics

by Dieter Uckelmann

The “EPCglobal Architecture Framework” is currently the most accepted technical approach to the Internet of Things and provides a solid foundation for building Business-to-Business information networks based on unique identifications of ‘things’. Lately, the vision of the Internet of Things has been extended to a more holistic approach that integrates sensors as well as actuators and includes non-business stakeholders. A detailed look at the current state of the art in research concerning cost and benefit estimations is provided and the limits of Cost Benefit Sharing for RFID-based IT-infrastructures are explained. In this work a market driven evaluation based on sales potential of information is developed. Simple technical means for aggregation of micro values to a billable amount are discussed. The requirements for electronic billing infrastructure are defined and a matching e-billing solutions for an evaluation scenario is presented, providing a technical infrastructure to evaluate and bill product-related information in a future Internet of Things, based on an extended EPCglobal Architecture. Further opportunities and threats are discussed to provide an overview of its future potential. As a result it will contribute to the sustainable success of the Internet of Things itself.

Quantitative Anaesthesia: Low Flow and Closed Circuit (Anaesthesiologie und Intensivmedizin Anaesthesiology and Intensive Care Medicine #204)

by K. Ackern, H. Frankenberger, E. Konecny and Karl Steinbereithner

Quantitative anaesthesia - exact registration of the degree of anaesthesia - has long been the anaesthetist's dream. Such pre­ cision could decrease the risk for the patient. Can -this dream now be realized in the foreseeable future? And can the quantifi­ cation be technically verified? This workshop was organized for these questions to be discussed by a group of experts. Schleswig-Holstein was a logical location for such a gathering. Medical and associated technical advances have socioeconomic consequences: in Schleswig-Holstein there are nowadays more jobs in medical technology than in the traditional shipbuilding industry. The encouragement of medical research and related technical innovation is thus a central component of public poli­ cy. One result of this emphasis was the recent setting up of a study group on medical technology, one of the aims of which is to provide a forum in Schleswig-Holstein for meetings such as this. The intention is to consolidate Schleswig-Holstein's reputation as a centre for both medical-technical development and scien­ tific discussion. The organizers of this scientific workshop thank the Schleswig­ Holstein Ministry of Economics and Transport and Dragerwerk AG for their support.

Quantitative Analysis and Optimal Control of Energy Efficiency in Discrete Manufacturing System

by Yan Wang Cheng-Lin Liu Zhi-Cheng Ji

This book provides energy efficiency quantitative analysis and optimal methods for discrete manufacturing systems from the perspective of global optimization. In order to analyze and optimize energy efficiency for discrete manufacturing systems, it uses real-time access to energy consumption information and models of the energy consumption, and constructs an energy efficiency quantitative index system. Based on the rough set and analytic hierarchy process, it also proposes a principal component quantitative analysis and a combined energy efficiency quantitative analysis. In turn, the book addresses the design and development of quantitative analysis systems. To save energy consumption on the basis of energy efficiency analysis, it presents several optimal control strategies, including one for single-machine equipment, an integrated approach based on RWA-MOPSO, and one for production energy efficiency based on a teaching and learning optimal algorithm. Given its scope, the book offers a valuable guide for students, teachers, engineers and researchers in the field of discrete manufacturing systems.

Quantitative Analysis in Nuclear Medicine Imaging

by Habib Zaidi

This book provides a review of image analysis techniques as they are applied in the field of diagnostic and therapeutic nuclear medicine. Driven in part by the remarkable sophistication of nuclear medicine instrumentation and - crease in computing power and its ready and inexpensive availability, this is a relatively new yet rapidly expanding field. Likewise, although the use of nuclear imaging for diagnosis and therapy has origins dating back almost to the pioneering work of Dr G. de Hevesy, quantitative imaging has only recently emerged as a promising approach for diagnosis and therapy of many diseases. An effort has, therefore, been made to place the reviews provided in this book in a broader context. The effort to do this is reflected by the inclusion of introductory chapters that address basic principles of nuclear medicine instrumentation and dual-modality imaging, followed by overview of issues that are closely related to quantitative nuclear imaging and its potential role in diagnostic and therapeutic applications. A brief overview of each chapter is provided below. Chapter 1 presents a general overview of nuclear medicine imaging physics and instrumentation including planar scintigraphy, single-photon emission computed tomography (SPECT) and positron emission tomography (PET). Nowadays, patients’ diagnosis and therapy is rarely done without the use of imaging technology. As such, imaging considerations are incorporated in almost every chapter of the book. The development of dual-modality - aging systems is an emerging research field, which is addressed in chapter 2.

Quantitative Analysis of Cellular Drug Transport, Disposition, and Delivery (Methods in Pharmacology and Toxicology)

by Gus R. Rosania Greg M. Thurber

This thorough book explores some of the most important methods and concepts affecting the quantitative analysis of the transport, targeting, and disposition of chemicals within cells, which in turn impact the macroscopic pharmacokinetics of chemical agents in the whole organism. The first half of the volume focuses on small organic molecules with drug-like characteristics, while the second half delves into the cellular pharmacokinetics of biologics and other macromolecules, including peptide therapeutics, cyclotides, antibodies, as well as nanoparticles, thus creating a comprehensive treatise that approaches cellular pharmacokinetics from the different perspectives of pharmaceutical scientists, chemical biologists, medicinal chemists, and protein engineers dealing with very different chemical agents spanning a wide range of sizes, physicochemical properties, and targeting mechanisms. Written for the Methods in Pharmacology and Toxicology series, chapters provide the kind of key detail and expert implementation advice that leads to excellent results in the lab. Synthetic biologists, biophysicists, and bioengineers are amongst the long list of scientists who could benefit from reading this book or from using it as a textbook. Authoritative and practical, Quantitative Analysis of Cellular Drug Transport, Disposition, and Delivery builds on a long history of drug development and the adding of quantitative methods at the cellular scale in order to inspire new approaches to drug development that are better able to take advantage of phenomena such as soluble-to-insoluble phase transitions or bispecific targeting, which could ultimately be exploited for the development of more effective drug delivery systems and therapeutic agents.
