Respiratory and cardiac motion leads to image degradation in Positron Emission Tomography (PET), which impairs quantification. In this book, the authors present approaches to motion estimation and motion correction in thoracic PET. The approaches for motion estimation are based on dual gating and mass-preserving image registration (VAMPIRE) and mass-preserving optical flow (MPOF). With mass-preservation, image intensity modulations caused by highly non-rigid cardiac motion are accounted for. Within the image registration framework different data terms, different variants of regularization and parametric and non-parametric motion models are examined. Within the optical flow framework, different data terms and further non-quadratic penalization are also discussed. The approaches for motion correction particularly focus on pipelines in dual gated PET. A quantitative evaluation of the proposed approaches is performed on software phantom data with accompanied ground-truth motion information. Further, clinical applicability is shown on patient data. The book concludes with an outlook of recent developments and potential future advances in the field of PET motion correction.

Today, climate change is among the most hotly-debated topics. The Clean Development Mechanism (CDM), one of the three financial mechanisms under the Kyoto Protocol open to developing and developed countries, was devised to assist in mitigation of global warming. This book discusses what China should do to make full use of the CDM to promote sustainable development and to meet the challenge of climate change from a legal perspective. The findings lead to the conclusion that the CDM has limitations in promoting sustainable development in China, and thus should be regarded only as a complementary instrument in combating climate change. Legal strategies for improving the implementation of CDM projects under the legal framework in China are thus put forward, and some proposals for China to meet the challenge of climate change in the post-2012 era are made.This book offers new insights to academics and policymakers both in the public and private sector. It is intended for legal practitioners and researchers on carbon trading as well as policymakers interested in the role of developing countries in climate change law. In addition, it is of interest to stakeholders of CDM projects.

Dieses Buch bietet eine systematische Einführung in dieses neue Arbeitsfeld der automatischen Bildanalyse. Es behandelt sämtliche wichtigen Teilaspekte, beginnend mit der Gewinnung von Tiefenbildern durch passive und aktive Verfahren über die Extraktion charakteristischer Flächenmerkmale und die Segmentierung bis hin zur modellbasierten Objekterkennung. Daneben werden konkrete Anwendungen der Tiefenbildanalyse vorgestellt. Die Didaktik des Buches erlaubt es Forschern und Praktikern, sich selbständig in dieses Gebiet einzuarbeiten. Das teilweise schwer zugängliche Material wurde in einheitlicher Notation und verständlicher Form aufbereitet. Die beschriebenen Verfahren können damit leicht auf dem Computer implementiert werden. Die Literaturhinweise geben einen vollständigen Überblick über die aktuelle Forschung.
