Book Description
In this thesis, we improve the standard 3D medical image interactive segmentation workflow. Drawing from the field of Active Learning, we propose a method for automating the process of deciding where the user should provide input next for optimally improving the segmentation. Specifically, we evaluate a given intermediate segmentation by constructing an uncertainty field over the image domain based on a multitude of segmentation quality metrics. We then find the plane that intersects with maximal uncertainty, and present it to the user for segmentation as an active batch query. We demonstrate the method through two embodiments, one using the Random Walker segmentation algorithm, and the other using the 3D Livewire method as seen in the software tool, TurtleSeg. We show that in both implementations, our method makes better decisions than user intuition and greatly reduces user interaction time.

Book Description
This book provides a thorough overview of the ongoing evolution in the application of artificial intelligence (AI) within healthcare and radiology, enabling readers to gain a deeper insight into the technological background of AI and the impacts of new and emerging technologies on medical imaging. After an introduction on game changers in radiology, such as deep learning technology, the technological evolution of AI in computing science and medical image computing is described, with explanation of basic principles and the types and subtypes of AI. Subsequent sections address the use of imaging biomarkers, the development and validation of AI applications, and various aspects and issues relating to the growing role of big data in radiology. Diverse real-life clinical applications of AI are then outlined for different body parts, demonstrating their ability to add value to daily radiology practices. The concluding section focuses on the impact of AI on radiology and the implications for radiologists, for example with respect to training. Written by radiologists and IT professionals, the book will be of high value for radiologists, medical/clinical physicists, IT specialists, and imaging informatics professionals.

Book Description
Rapid progress in the technique and practice of virtual colonoscopy as well as the conti- ing clinical high interest for this radiodiagnostic procedure made this second edition, only 3 years after the publication of the ? rst edition of this successful volume, necessary. This new edition includes the latest study results and technical developments of this exciting noninvasive diagnostic modality for the evaluation of the colon. The technical presentation and lay out of the text and of the many new illustrations are impeccable. The editors were again able to ensure the collaboration of many international leaders in the ? eld and the book offers a very comprehensive overview of all aspects and issues of CT colonography with a focus on how to perform practically this examination, which requires meticulous technique starting from rigorous preparation, then the conduct of the study itself, and ? nally the interpretation of the results. I am very much indebted to the editors and the collaborating authors for preparing this outstanding volume in a record short time period, which enabled them to include the latest technical advances in this rapidly evolving important radiological method. It is highly recommended to general and gastrointestinal radiologists as well as gast- eneterologists as a most welcome update of their knowledge and as a practical guide in their daily practice. I am convinced that this second edition will meet the same success with our readership as the ? rst one.

Book Description
Atlas of Early Zebrafish Brain Development: A Tool for Molecular Neurogenetics, Second Edition, remains the only neuroanatomical expression atlas of important genetic and immunohistochemical markers of this vertebrate model system. It represents a key reference and interpretation matrix for analyzing expression domains of genes involved in Zebrafish brain development and neurogenesis, and serves as a continuing milestone in this research area. This updated volume provides in-situ hybridized and immunostained preparations of complete series of brain sections, revealing markers of the fundamental stages in the life history of neuronal cells in very high quality preparations and photographic plates. Specific additions to this edition include documentation on the distribution of neurons expressing GABA, dopamine and serotonin, material on the basal ganglia, hypothalamus, and the caudal, segmented part of the diencephalon, new theories on the early organization of the telencephalon and thalamus, and integration of a comparative perspective on the mid- and hindbrain.
