Sommario/riassunto

This volume is based on lectures given during the program Complex Quantum Systems held at the National University of Singapore's Institute for Mathematical Sciences from 17 February to 27 March 2010. It guides the reader through two introductory expositions on large Coulomb systems to five of the most important developments in the field: derivation of mean field equations, derivation of effective Hamiltonians, alternative high precision methods in quantum chemistry, modern many body methods originating from quantum information, and - the most complex - semirelativistic quantum electrodynamics.

Sommario/riassunto

This book is a detailed review of optical coherence tomography (OCT) in cardiovascular practice. OCT enables cross-sectional and volumetric imaging of internal structure and pathology in biological tissues, thus performing an “optical biopsy”, imaging pathology in situ and in real time without the need for excisional biopsy. OCT imaging has become a standard of care in ophthalmology and is an emerging imaging modality in cardiology, where it provides information that often cannot be obtained by any other means. This book provides readers who are not familiar with image interpretation and don’t have enough background/knowledge with information on its clinical use and potential. Cardiovascular OCT Imaging is designed for busy interventional cardiologists and cardiologists to quickly become familiar with this emerging technology so that they can take advantage of its power to improve patient care and outcome. It will therefore be of great interest to all involved in interventional cardiology from trainees



to practicing physicians and technologists.
