Basic physics of ultrasonic imaging

The present volume on basic physics of ultrasonographic imaging procedures provides clear and concise information on the physics behind ultrasound examinations in diagnostic imaging. It attempts to present the subject from a simple approach that should make it possible for the target groups to comprehend the important concepts which form the physical basis of ultrasonic imaging. The main target group of this manual is radiological technologists and radiographers working with diagnostic ultrasound in developing countries. Clinicians and nurse practitioners may also find the simple presentation appealing. A conscious effort has been made to avoid detailed mathematical treatment of the subject. The emphasis is on simplicity.

Digital Radiography in Practice

by Quinn B. Carroll (Author)

Medical radiography programs will appreciate having an economical textbook that focuses on the practical aspects of digital radiography. Nearly all textbooks to date claiming the title digital radiography have dealt primarily with the managerial aspects of the topic at the expense of any practical information on how digital imaging works and its clinical implications for the daily practice of radiography. The goal of this book is to provide an accurate and adequate description of all the aspects of digital images and digital equipment, and their implications for radiographic technique and clinical application in a student-friendly way by providing crisp, clear illustrations along with readable text. Many of the lucid illustrations in this textbook are from the author’s comprehensive textbook, Radiography in the Digital Age (Charles C Thomas, 2018), to make digital radiography comprehensible to the student, but in this book the focus is only on digital topics and the facts are stated with such brief explanatory material as each topic will allow. Many digital topics are intimidating, and every attempt is made to reduce these topics to a descriptive, non-mathematical level that can be intuitively understood by the average student. A helpful glossary is included whenever a concise definition is needed for a particular term.

Review
This is a textbook concentrating on digital imaging in a radiography department. As a radiographer I have used and reported both CR and DR images, and have been involved in departments transitioning between the two. The chapters are laid out in a good order, leading from the very basics of understanding the digital machine and how the images are produced, through to post-processing of images, and how they are best displayed, finishing with information about reporting screen quality, quality control for the machines and a final chapter introducing digital fluoroscopy. The information is worth the retail price. The content of each chapter is laid out well, with a good mix of pictures and diagrams breaking up the text. The use of radiography language helps to make it understandable, and walks you through the sometimes complex physics of image acquisition. There is good information on the capabilities and also the limitations of the equipment, and the quizzes at the end of each chapter help to cement the learning from the readings. There is an emphasis on image quality and an understanding that all radiographers should work to the ALARP principle, and how digital equipment can help this. It explains the issues with both under exposure and over exposure on image manipulation and reporting. As an American book it only mentions radiologists, but it is equally important for reporting radiographers to understand image manipulation. The information in the book would be beneficial to student radiographers and also has a place in the modern radiography department switching from CR to DR, or looking to understand the capabilities of their machinery and to get the best out of it. It will help with technical questions that may need to be asked of each manufacturer if new equipment is being sourced. I now understand more about the machinery and the imaging, and the relationship between the exposure index and the deviation index, and the limitation of manipulating the image at source for the reporter. The glossary at the end is a comprehensive list with explanation of all the terminology we should all be aware of and often use, and is a good reference point to help the all-round knowledge needed to understand DR imaging. –Hilary Rose, reporting radiographer, Weston Area Health NHS Trust / RAD Magazine / February 2020

Fast Quantitative Magnetic Resonance Imaging

Among medical imaging modalities, magnetic resonance imaging (MRI) stands out for its excellent soft-tissue contrast, anatomical detail, and high sensitivity for disease detection. However, as proven by the continuous and vast effort to develop new MRI techniques, limitations and open challenges remain. The primary source of contrast in MRI images are the various relaxation parameters associated with the nuclear magnetic resonance (NMR) phenomena upon which MRI is based. Although it is possible to quantify these relaxation parameters (qMRI) they are rarely used in the clinic, and radiological interpretation of images is primarily based upon images that are relaxation time weighted. The clinical adoption of qMRI is mainly limited by the long acquisition times required to quantify each relaxation parameter as well as questions around their accuracy and reliability. More specifically, the main limitations of qMRI methods have been the difficulty in dealing with the high inter-parameter correlations and a high sensitivity to MRI system imperfections.

Recently, new methods for rapid qMRI have been proposed. The multi-parametric models at the heart of these techniques have the main advantage of accounting for the correlations between the parameters of interest as well as system imperfections. This holistic view on the MR signal makes it possible to regress many individual parameters at once, potentially with a higher accuracy. Novel, accurate techniques promise a fast estimation of relevant MRI quantities, including but not limited to longitudinal (T1) and transverse (T2) relaxation times. Among these emerging methods, MR Fingerprinting (MRF), synthetic MR (syMRI or MAGIC), and T1-T2 Shuffling are making their way into the clinical world at a very fast pace. However, the main underlying assumptions and algorithms used are sometimes different from those found in the conventional MRI literature, and can be elusive at times. In this book, we take the opportunity to study and describe the main assumptions, theoretical background, and methods that are the basis of these emerging techniques.

Quantitative transient state imaging provides an incredible, transformative opportunity for MRI. There is huge potential to further extend the physics, in conjunction with the underlying physiology, toward a better theoretical description of the underlying models, their application, and evaluation to improve the assessment of disease and treatment efficacy.
