Magnetic Resonance Imaging (MRI) is among the most important medical imaging techniques available today. There is an installed base of approximately 15,000 MRI scanners worldwide. Each of these scanners is capable of running many different "pulse sequences", which are governed by physics and engineering principles, and implemented by software programs that control the MRI hardware. To utilize an MRI scanner to the fullest extent, a conceptual understanding of its pulse sequences is crucial. Handbook of MRI Pulse Sequences offers a complete guide that can help the scientists, engineers, clinicians, and technologists in the field of MRI understand and better employ their scanner. - Explains pulse sequences, their components, and the associated image reconstruction methods commonly used in MRI - Provides self-contained sections for individual techniques - Can be used as a quick reference guide or as a resource for deeper study - Includes both non-mathematical and mathematical descriptions - Contains numerous figures, tables, references, and worked example problems
Building value in our global economy increasingly demands creating new opportunities and solving new problems. In a nutshell, that's what inventors do. Just as software has driven growth and opened new markets over the past generation, invention is poised to become the X-factor for the future. With a foreword by former Microsoft research chief Nathan Myhrvold, this groundbreaking book takes us inside the laboratories and inside the minds of some of today's leading inventors to demystify the critical process by which they imagine and create. Evan I. Schwartz argues that invention has remained steeped in myth and misunderstanding. We tend to view invention as a byproduct of accidental discover...
At the heart of every medical imaging technology is a sophisticated mathematical model of the measurement process and an algorithm to reconstruct an image from the measured data. This book provides a firm foundation in the mathematical tools used to model the measurements and derive the reconstruction algorithms used in most imaging modalities in current use. In the process, it also covers many important analytic concepts and techniques used in Fourier analysis, integral equations, sampling theory, and noise analysis.This text uses X-ray computed tomography as a "pedagogical machine" to illustrate important ideas and incorporates extensive discussions of background material making the more a...
The following analysis illustrates the underlying trends and relationships of U.S. issued patents of the subject company. The analysis employs two frequently used patent classification methods: US Patent Classification (UPC) and International Patent Classification (IPC). Aside from assisting patent examiners in determining the field of search for newly submitted patent applications, the two classification methods play a pivotal role in the characterization and analysis of technologies contained in collections of patent data. The analysis also includes the company’s most prolific inventors, top cited patents as well as foreign filings by technology area.
At its current rate, technological development has outpaced corresponding changes in international law. Proposals to remedy this deficiency have been made, in part, by members of the Shanghai Cooperation Organization (led by the Russian Federation), but the United States and select allies have rejected these proposals, arguing that existing international law already provides a suitable comprehensive framework necessary to tackle cyber-warfare. Cyber-Attacks and the Exploitable Imperfections of International Law does not contest (and, in fact, supports) the idea that contemporary jus ad bellum and jus in bello, in general, can accommodate cyber-warfare. However, this analysis argues that existing international law contains significant imperfections that can be exploited; gaps, not yet filled, that fail to address future risks posed by cyber-attacks.
