Radiography is a versatile technique with many applications to archaeological and art historical artefacts. It can be used to assess the condition of objects before conservation treatment, to gain insight into materials used and methods of construction, and to reveal teh secrets of teh embalmer's art, hidden within mummified remains. The techniques can be applied to materials as diverse as paper, wood, ceramic and metal, as well as to human and other animal remains. Radiographic examination may provide images of objects concealed within a mass of corrosion and may even reveal a previously unknown painting, hidden beneath a later work. All of this can be carried out non-destructively, making radiography an invaluable tool for the study of cultural materials. This book explores some of this multitude of applications through a series of chapters, each written by practitioners in their particular field. These accounts include descriptions of some less familiar methods, such as xeroradiography, stereoradiography and the application of recenty introduced image processing techniques. They demonstrate vividly the versatility of radiography, and the range of topics discussed illustrates the valuable contribution that radiography can make to the study of artfacts made from a variety of materials, from many different cultures. For the most part, the book is arranged on the basis of the nature of the materials studied; the particular concerns of the conservator are then consdered, followed by a discussion of the use of radiography in the detection of restoration, pastiche and fakes. The final chapter provides an account of the application of computer-based image processing techniques. Written by experts in their particular fields Of interest to the conservator and curator alike Illustrated with over 200 photos and line drawings

Radiography can be an invaluable tool for the study of a diverse array of cultural materials including metals, ceramics, paper, paintings and human and animal remains. In this book, experts in the field bring to life their experiences with the different materials, describing the techniques that can be employed to discover the stories behind the objects. This second edition, available in paperback for the first time, includes new case studies and images, as well as whole new sections on digital imaging, quality control and animal mummies.

X-radiography of textile objects reveals hidden features as well as unexpected components and materials. This non-destructive technique throws light on construction, manufacturing techniques, use, wear, repair, patterns of decay and dating. X-radiography improves artefact documentation and interpretation as well as guiding conservation approaches by enhancing understanding. This book explores techniques for X-raying textiles. It describes approaches to image interpretation and explains how, through digitisation and digital image manipulation, maximum information can be realised. Case studies include archaeological, ecclesiastical and ethnographic textiles, items of dress and accessories, upholstery, quilts, embroideries, dolls and toys. Museum professionals will find this stimulating book an essential guide for developing their own practice or commissioning textile X-radiographs.

Containing chapter contributions from over 130 experts, this unique publication is the first handbook dedicated to the physics and technology of X-ray imaging, offering extensive coverage of the field. This highly comprehensive work is edited by one of the world’s leading experts in X-ray imaging physics and technology and has been created with guidance from a Scientific Board containing respected and renowned scientists from around the world. The book's scope includes 2D and 3D X-ray imaging techniques from soft-X-ray to megavoltage energies, including computed tomography, fluoroscopy, dental imaging and small animal imaging, with several chapters dedicated to breast imaging techniques. 2D and 3D industrial imaging is incorporated, including imaging of artworks. Specific attention is dedicated to techniques of phase contrast X-ray imaging. The approach undertaken is one that illustrates the theory as well as the techniques and the devices routinely used in the various fields. Computational aspects are fully covered, including 3D reconstruction algorithms, hard/software phantoms, and computer-aided diagnosis. Theories of image quality are fully illustrated. Historical, radioprotection, radiation dosimetry, quality assurance and educational aspects are also covered. This handbook will be suitable for a very broad audience, including graduate students in medical physics and biomedical engineering; medical physics residents; radiographers; physicists and engineers in the field of imaging and non-destructive industrial testing using X-rays; and scientists interested in understanding and using X-ray imaging techniques. The handbook's editor, Dr. Paolo Russo, has over 30 years’ experience in the academic teaching of medical physics and X-ray imaging research. He has authored several book chapters in the field of X-ray imaging, is Editor-in-Chief of an international scientific journal in medical physics, and has responsibilities in the publication committees of international scientific organizations in medical physics. Features: Comprehensive coverage of the use of X-rays both in medical radiology and industrial testing The first handbook published to be dedicated to the physics and technology of X-rays Handbook edited by world authority, with contributions from experts in each field

The application of X-rays to objects of archaeology and insights into construction and chemical composition in a non-destructive manner date back to the discovery of radiation. This book contains measurement data taken with portable XRF and XRD, and data taken with accelerating ion beams and synchrotron radiations, and with their explanation.

/inca/publications/misc/creaghcov.htmAbout the coverThis book contains twenty chapters covering a wide range of research in the fields of scientific conservation of art and archaeometry. The common thread is the use of radiation in these analyses. The term "radiation" is used in the widest possible sense. The book encompasses the use of electromagnetic radiation in its microwave, infrared, visible, ultraviolet, x ray and &ggr; ray forms and the use of particulate forms such as electrons, neutrons and charged particles for which the Planck's Law relation applies. In many cases there is an interplay between the two forms: for example, proton induced x ray emission (PIXE), secondary ion mass spectrometry (SIMS). As far as possible the chapters have been arranged in order of ascending particle energy. Thus it commences with the use of microwaves and finishes with the use of &ggr; rays. The authors were chosen on the basis of their expertise as practitioners of their particular field of study. This means that, for example, the mature fields of study such as the IR and UV study of paintings have been written by senior researchers, whereas for the emerging fields of synchrotron and neutron techniques the chapters have been written by talented researchers at the commencement of their careers.
