High-Resolution Radiographs of the Hand


Book Description

Plain radiography is still alive. In many institutions, including ours, conventional radiography has been replaced by digital systems including imaging-plate-based computed radiography and fat-panel detector-based digital radiography. Even for the education of radiation technologists, conventional flm-screen radiography has been de-- phasized, and their education is concentrated on digital systems. Spatial resolution of a conventional system is still far better than the current digital systems, although the dynamic range is wider in the latter system. Industrial flm radiography with small grain size and direct exposure has an even higher resolution, and such hi- resolution systems are something we lost in the transition from the conventional system to the current PACS-friendly system. I am pleased to know that Giuseppe Guglielmi and Wilfred Peh have published this textbook of high-resolution hand radiographs that cannot be obtained with any other techniques. Radiography has always been the most important modality in the evaluation of the hand, and, moreover, high-resolution industrial flms are extremely efective in the evaluation of the hand, particularly for assessing subtle erosions. Hands are not just one of the peripheries of the human body. Tey refect conditions of the whole human body. Not only the metabolic status, but also many congenital disorders are manifested in the hand. Radiographic fndings of the hand are ofen specifc, and contribute to the diagnoses a great deal. Tere have been several publications concerning the radiology of the hand, and they have been well accepted.




Medical Imaging Systems


Book Description

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.




High Resolution X-Ray Diffractometry And Topography


Book Description

The rapid growth in the applications of electronic materials has created an increasing demand for reliable techniques for examining and characterizing these materials. This book explores the area of x-ray diffraction and the techniques available for deployment in research, development, and production. It maps the theoretical and practical background necessary to study single crystal materials using high resolution x-ray diffraction and topography. It combines mathematical formalism with graphical explanations and hands-on advice for interpreting data, thus providing the theoretical and practical background for applying these techniques in scientific and industrial materials characterization




High-Resolution X-Ray Scattering


Book Description

During the last 20 years interest in high-resolution x-ray diffractometry and reflectivity has grown as a result of the development of the semiconductor industry and the increasing interest in material research of thin layers of magnetic, organic, and other materials. For example, optoelectronics requires a subsequent epitaxy of thin layers of different semiconductor materials. Here, the individuallayer thicknesses are scaled down to a few atomic layers in order to exploit quantum effects. For reasons of electronic and optical confinement, these thin layers are embedded within much thicker cladding layers or stacks of multilayers of slightly different chemical composition. It is evident that the interface quality of those quantum weHs is quite important for the function of devices. Thin metallic layers often show magnetic properties which do not ap pear for thick layers or in bulk material. The investigation of the mutual interaction of magnetic and non-magnetic layers leads to the discovery of colossal magnetoresistance, for example. This property is strongly related to the thickness and interface roughness of covered layers.




Imaging of Foreign Bodies


Book Description

Most ingested foreign bodies pass through the gastrointestinal tract without a problem. However, both ingested and inserted foreign bodies may cause bowel obstruction or perforation or lead to severe hemorrhage, abscess formation, or septicemia. Foreign body aspiration is common in children, especially those under 3 years of age, and in these cases chest radiography and CT are the main imaging modalities. This textbook provides a thorough overview of the critical role of diagnostic imaging in the assessment of patients with suspected foreign body ingestion, aspiration, or insertion. A wide range of scenarios are covered, from the common problem of foreign body ingestion or aspiration in children and mentally handicapped adults through to drug smuggling by body packing and gunshot wounds. Guidance is offered on diagnostic protocols, and the value of different imaging modalities in different situations is explained. Helpful management tips are also provided. This textbook will prove invaluable for residents in radiology, radiologists, and physicians who are involved on a daily basis, within an emergency department, in the management of patients with suspected ingestion, aspiration, or insertion of foreign bodies.​




The Radiology Handbook


Book Description

Designed for busy medical students, The Radiology Handbook is a quick and easy reference for any practitioner who needs information on ordering or interpreting images. The book is divided into three parts: - Part I presents a table, organized from head to toe, with recommended imaging tests for common clinical conditions. - Part II is organized in a question and answer format that covers the following topics: how each major imaging modality works to create an image; what the basic precepts of image interpretation in each body system are; and where to find information and resources for continued learning. - Part III is an imaging quiz beginning at the head and ending at the foot. Sixty images are provided to self-test knowledge about normal imaging anatomy and common imaging pathology. Published in collaboration with the Ohio University College of Osteopathic Medicine, The Radiology Handbook is a convenient pocket-sized resource designed for medical students and non radiologists.

Covering practices ranging from ultrasound at the point of care to the interpretation of CT scan results, this book contains over 2,200 images, each with detailed captions and line-art that highlight key findings. Within each section, particular attention is devoted to practical tricks of the trade and tips for avoiding common pitfalls. Overall, this book is a useful source for experienced clinicians, residents, mid-level providers, or medical students who want to maximize the diagnostic accuracy of each modality without losing valuable time.




Skeletal Development of the Hand and Wrist


Book Description

Bone age assessment, a crucial part of the diagnosis and management of pediatric growth disorders as well as the timing of certain pediatric orthopedic procedures, has for decades depended on the meticulous examination of plain radiographs. Examining the subtle changes present within the maturing human hand often proves to be challenging and time-consuming. Building on the popular Greulich and Pyle atlas, this book modernizes the method for pediatric skeletal maturity determination. It offers a wealth of images, carefully mined from thousands of digital radiographs from University of Virginia's Picture Archiving and Communication System (PACS), edited to best demonstrate important developmental bone features, and organized by age and sex for rapid reference. To expedite learning and clinical image analysis, images come in pairs: annotated and unannotated, for easy comparison. Succinct annotations on the images replace lengthy text to provide a quicker and clearer understanding of the skeletal age. These annotations highlight important and subtle features to help distinguish images that otherwise look superficially alike. The result is an atlas of exceptionally high quality skeletal radiographic standards that capture both the major and finer details of the accepted standards of Greulich and Pyle. The user-friendly format of this book enables a faster, more accurate, and more educational approach to determining skeletal maturity. The Digital Bone Age Companion packaged with the book is a computer program that facilitates viewing of the atlas images in digital format. Users can easily zoom in on radiographic features, set image level and width to their preference, and compare two or three reference standards side-by-side for difficult cases. Most importantly, the program expedites evaluation, optimizes workflow, and minimizes user-introduced errors with the reliable bone age calculator and built-in report generator. The digital format may also be available for integration with your Radiology Information System (RIS) for further workflow enhancement. Given the broad application of pediatric bone aging, Skeletal Development of the Hand and Wrist is not only intended for practicing and training radiologists, but for all of those who employ bone age studies as part of their practice.
