A companion to the Insight Toolkit An introduction to the theory of modern medical image processing, including the analysis of data from - X-ray computer tomography, - magnetic resonance imaging, - nuclear medicine, - and ultrasound. Using an algorithmic approach, and providing the mathematical, statistical, or signal processing as needed for background, the authors describe the principles of all methods implemented in the Insight Toolkit (ITK), a freely available, open- source, object-oriented library. The emphasis is on providing intuitive descriptions of the principles and illustrative examples of results from the leading filtering, segmentation, and registration methods. This book covers the mathematical foundations of important techniques such as: - Statistical pattern recognition, - PDE-based nonlinear image filtering, - Markov random fields, - Level set methods, - Deformable models, - Mutual information, image-based registration - Non-rigid image data fusion With contributions from: Elsa Angelini, Brian Avants, Stephen Aylward, Ting Chen, Jeffrey Duda, Jim Gee, Luis Ibanez, Celina Imielinska, Yinpeng Jin, Jisung Kim, Bill Lorensen, Dimitris Metaxas, Lydia Ng, Punam Saha, George Stetten, Tessa Sundaram, Jay Udupa, Ross Whitaker, Terry Yoo, and Ying Zhuge. The Insight Toolkit is part of the Visible Human Project from the National Library of Medicine, with support from NIDCR, NINDS, NIMH, NEI, NSF, TATRC, NCI, and NIDCD.

Miles's pathbreaking work shows how art and architecture have shaped religious understanding throughout the history of Christianity.

The notion of the painting as an art object is a relatively recent invention. The Self-Aware Image offers an impressive and complex account of the origins and development of this invention from the late Renaissance through the end of the baroque age. In comparison to the old image characterized by its preeminently liturgical function and its display in a predetermined space, the painting as the new image is increasingly autonomous and movable. As a modern art object, the painting becomes the focus of an aesthetic contemplation through its insertion into a gallery or a collection. As a result of the Protestant iconoclasm and the advancement of scientific knowledge, the essence and role of the image is put into question and thematized not only by theologians and scholars, but especially by artists. The painting thus becomes a field of visual experimentation in which art reflects on itself, its potential, its limits, its truth, and its nothingness. The representation of windows, doors, niches, mirrors, and paintings enable artists to embed the image within the image, to frame the fictiveness of the image in order to deceive, puzzle, and challenge the beholder. The pictorial devices through which artists introduce their authorial self into the image and stage the making of the image itself form the foundation of a new poetics: the poetics of metapainting. First published in French in 1993, Victor Stoichita's Self-Aware Image has become a classic of the history of art. This new, updated, and improved English edition marks the twentieth anniversary of a work that radically changed the perception of seventeenth-century art and that constitutes an ever-valid reference for contemporary scholarship. An introduction by Lorenzo Pericolo illustrates the great importance of the book for our comprehension of baroque painting.

This textbook, intended for advanced undergraduate and graduate students, is an introduction to the physical and mathematical principles used in clinical medical imaging. The first two chapters introduce basic concepts and useful terms used in medical imaging and the tools implemented in image reconstruction, while the following chapters cover an array of topics such as physics of x-rays and their implementation in planar and computed tomography (CT) imaging; nuclear medicine imaging and the methods of forming functional planar and single photon emission computed tomography (SPECT) images and Clinical imaging using positron emitters as radiotracers. The book also discusses the principles of MRI pulse sequencing and signal generation, gradient fields, and the methodologies implemented for image formation, form flow imaging and magnetic resonance angiography and the basic physics of acoustic waves, the different acquisition modes used in medical ultrasound, and the methodologies implemented for image formation and flow imaging using the Doppler Effect. By the end of the book, readers will know what is expected from a medical image, will comprehend the issues involved in producing and assessing the quality of a medical image, will be able to conceptually implement this knowledge in the development of a new imaging modality, and will be able to write basic algorithms for image reconstruction. Knowledge of calculus, linear algebra, regular and partial differential equations, and a familiarity with the Fourier transform and it applications is expected, along with fluency with computer programming. The book contains exercises, homework problems, and sample exam questions that are exemplary of the main concepts and formulae students would encounter in a clinical setting.

In this book, Warren Keller reveals the secrets of astro-image processing software PixInsight in a practical and easy to follow manner, allowing the reader to produce stunning astrophotographs from even mediocre data. As the first comprehensive post-processing platform to be created by astro-imagers for astro-imagers, it has for many, replaced the generic graphics editors as the software of choice. With clear instructions from Keller, astrophotographers can get the most from its tools to create amazing images. Capable of complex post-processing routines, PixInsight is also an advanced pre-processing software, through which astrophotographers calibrate and stack their exposures into completed master files. Although it is extremely powerful, PixInsight has been inadequately documented in print--until now. With screenshots to help illustrate the process, it is a vital guide.

In the history of black America, the image of the mortal, wounded, and dead black body has long been looked at by others from a safe distance. Courtney Baker questions the relationship between the spectator and victim and urges viewers to move beyond the safety of the "gaze" to cultivate a capacity for humane insight toward representations of human suffering. Utilizing the visual studies concept termed the "look," Baker interrogates how the notion of humanity was articulated and recognized in oft-referenced moments within the African American experience: the graphic brutality of the 1834 Lalaurie affair; the photographic exhibition of lynching, Without Sanctuary ; Emmett Till's murder and funeral; and the devastation caused by Hurricane Katrina. Contemplating these and other episodes, Baker traces how proponents of black freedom and dignity used the visual display of violence against the black body to galvanize action against racial injustice. An innovative cultural study that connects visual theory to African American history, Humane Insight asserts the importance of ethics in our analysis of race and visual culture, and reveals how representations of pain can become the currency of black liberation from injustice.

This book comprises a selection of William Hart McNichols's popular icons and sacred images into a single collection.
