Download or read book Quality Control and Artefacts in Magnetic Resonance Imaging written by Donald McRobbie and published by Institute of Physics and Engineering in Medicine. This book was released on 2017-01-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Quality Control and Artefacts in Magnetic Resonance Imaging is an authoritative, comprehensive and practical guide for all medical imaging professionals with an interest in evaluating and assuring image quality and scanner performance in MRI. Written by leading UK experts, the report is a major revision of IPEM Report 80: Quality Control in Magnetic Resonance Imaging. The report is in two parts. Part I deals with quality control, with chapters on test object design and test materials, signal parameter measurement (signal-to-noise ratio, ghosting, etc.), geometric parameters (resolution, distortion), slice parameters (position, width and profile), relaxometry and contrast. For each parameter a consistent and systematic structure provides a literature review with reference to current international standards, parameter definition, description of test methods, practical guidance including frequency of measurement, analysis and interpretation of results, and pitfalls. A specialist QC chapter is a new and unique feature providing guidance relating to specific clinical and research techniques: field mapping, diffusion, BOLD fMRI, voxel-based morphometry, dynamic contrast-enhanced MRI, quantitative velocity mapping, spectroscopy, and ultra-high field MRI. Part II provides a comprehensive and exhaustive encyclopaedia of MRI artefacts both common and rare arising from technical limitations and faults, patient and organ motion, tissue properties, intrinsic MR physics, and reconstruction limitations. Pictorial examples of each artefact from clinical or phantom images are provided along with a detailed explanation of the causes and advice on reducing, avoiding or removing the artefact. A summary table of artefact appearance, causes and remediation will enable readers to diagnose and solve their own artefact problems. The practical nature of the report is underpinned by academic rigour with 269 references and a comprehensive index. Quality Control and Artefacts in Magnetic Resonance is an essential reference for all MRI departments and MRI professionals.

Download or read book Artifacts and Technical Solutions in MR Diagnostic Imaging written by Luca Bartalini and published by Independently Published. This book was released on 2018-12-30 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for all those professionals directly or indirectly working in magnetic resonance, and arises from the need to have available a complete and comprehensible guide, in order to recognize, construe and work out almost all the artifacts that can currently be observed in the supplied scanners, being low-field, mid-field, high-field or ultra-high-field. The content includes many demonstrative images and few mathematical formula, moreover simple to be construed, in order to make easily comprehensible the complex mechanisms hidden behind MR Physics, connected to the artifact under consideration. The text presents a basic introduction to the magnetic resonance and a glossary of used acronyms, so that the principles related to k-space, impulse sequences and relaxation times are clearly understood. Artifacts are effectively classified in chapters and subchapters, according to the underlying cause generating them. Each artifacts group is dealt with following a logic providing for: -Introduction to the specific artifact-related technique.-Modes by which the artifact shows itself, on the basis of images and text.-Technical solutions suited to the resolutions.-Online examinations, videos, focuses, overview tables with access linked to the credentials obtained when purchasing the original text. MRI Technologist Dr. Luca Bartalini

Book excerpt: This renowned work is derived from the authors' acclaimed national review course (“Physics of Medical Imaging") at the University of California-Davis for radiology residents. The text is a guide to the fundamental principles of medical imaging physics, radiation protection and radiation biology, with complex topics presented in the clear and concise manner and style for which these authors are known. Coverage includes the production, characteristics and interactions of ionizing radiation used in medical imaging and the imaging modalities in which they are used, including radiography, mammography, fluoroscopy, computed tomography and nuclear medicine. Special attention is paid to optimizing patient dose in each of these modalities. Sections of the book address topics common to all forms of diagnostic imaging, including image quality and medical informatics as well as the non-ionizing medical imaging modalities of MRI and ultrasound. The basic science important to nuclear imaging, including the nature and production of radioactivity, internal dosimetry and radiation detection and measurement, are presented clearly and concisely. Current concepts in the fields of radiation biology and radiation protection relevant to medical imaging, and a number of helpful appendices complete this comprehensive textbook. The text is enhanced by numerous full color charts, tables, images and superb illustrations that reinforce central concepts. The book is ideal for medical imaging professionals, and teachers and students in medical physics and biomedical engineering. Radiology residents will find this text especially useful in bolstering their understanding of imaging physics and related topics prior to board exams.

Download or read book Image Artifact Reduction for Fast Magnetic Resonance Imaging written by Joseph Yitan Cheng and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic resonance imaging (MRI) is a rich source for diagnostic information. It has the ability to obtain excellent soft-tissue contrast at a very high spatial resolution. The imaging process of this modality can be conveniently described as a linear system with Fourier encoding. However, to increase flexibility and robustness, imaging techniques are used that cause basic assumptions of this model to fall apart. As a result, image artifacts arise, decreasing the clinical quality of the scans. More sophisticated methods that take these effects into account must be considered. Many of the errors reside in both the spatial and frequency domain, so simple linear solutions do not suffice. Two sources of image artifacts are investigated: (1) concomitant gradient field and field inhomogeneity and (2) nonrigid motion in free-breathing acquisitions. Each image-artifact source has specific effects which are dependent on the application. For real-time cardiac imaging with spiral k-space trajectories, concomitant gradient field and field inhomogeneity errors result in image blurring. Two fast and practical solutions are developed and applied to real-time cardiac studies and high-resolution cardiac studies. MRI is also a compelling choice for imaging pediatric patients as they are highly susceptible to risks of ionizing radiation of computed tomography and nuclear scintigraphy studies. However, this imaging modality is highly sensitive to motion. The motion can result in destructive image artifacts. To enable free-breathing volumetric exams, novel data acquisition strategies and image reconstruction techniques are developed to compensate for nonrigid respiratory motion. These methods are demonstrated in select pediatric patient studies. Image artifacts fromrespiratory motion are reduced from the free-breathing abdominal scans.
