"At the heart of every medical imaging technology is a sophisticated mathematical model of the measurement process and an algorithm to reconstruct an image from the measured data. This book provides a firm foundation in the mathematical tools used to model the measurements and derive the reconstruction algorithms used in most imaging modalities in current use. In the process, it also covers many important analytic concepts, and techniques used in Fourier analysis, integral equations, sampling theory, and noise analysis.This text uses X-ray computed tomography as a "pedagogical machine" to illustrate important ideas and incorporates extensive discussions of background material making the more advanced mathematical topics accessible to readers with a less formal mathematical education. The mathematical concepts are illuminated with over 200 illustrations and numerous exercises.New to the second edition are a chapter on magnetic resonance imaging (MRI), a revised section on the relationship between the continuum and discrete Fourier transforms, a new section on Grangreat formula, an improved description of the gridding method, and a new section on noise analysis in MRI."

"Essential radiology, third edition , is an extensively revised and updated text that provides a highly engaging, integrated overview of the use of radiology in every specialty and subspecialty, covering all imaging modalities and organ systems. It gives medical students in radiology clerkships a solid understanding of how each imaging modality works and how a variety of pathologic conditions appear on different imaging modalities."

"This book provides a thorough overview of the ongoing evolution in the application of artificial intelligence (AI) within healthcare and radiology, enabling readers to gain a deeper insight into the technological background of AI and the impacts of new and emerging technologies on medical imaging. After an introduction on game changers in radiology, such as deep learning technology, the technological evolution of AI in computing science and medical image computing is described, with explanation of basic principles and the types and subtypes of AI. Subsequent sections address the use of imaging biomarkers, the development and validation of AI applications, and various aspects and issues relating to the growing role of big data in radiology. Diverse real-life clinical applications of AI are then outlined for different body parts, demonstrating their ability to add value to daily radiology practices. The concluding section focuses on the impact of AI on radiology and the implications for radiologists, for example with respect to training. Written by radiologists and IT professionals, the book will be of high value for radiologists, medical/clinical physicists, IT specialists, and imaging informatics professionals"

"Radiology fundamentals is a concise introduction to the dynamic field of radiology for medical students, non-radiology house staff, physician assistants, nurse practitioners, radiology assistants, and other allied health professionals. The goal of the book is to provide readers with general examples and brief discussions of basic radiographic principles and to serve as a curriculum guide, supplementing a radiology education and providing a solid foundation for further learning. Introductory chapters provide readers with the fundamental scientific concepts underlying the medical use of imaging modalities and technology, including ultrasound, computed tomography, magnetic resonance imaging, and nuclear medicine. The main scope of the book is to present concise chapters organized by anatomic region and radiology sub-specialty that highlight the radiologist’s role in diagnosing and treating common diseases, disorders, and conditions. Highly illustrated with images and diagrams, each chapter in Radiology Fundamentals begins with learning objectives to aid readers in recognizing important points and connecting the basic radiology concepts that run throughout the text. It is the editors’ hope that this valuable, up-to-date resource will foster and further stimulate self-directed radiology learning—the process at the heart of medical education."

"Summary: Known as the bible of biomedical engineering, The Biomedical Engineering Handbook, Fourth Edition, sets the standard against which all other references of this nature are measured. As such, it has served as a major resource for both skilled professionals and novices to biomedical engineering. Biomedical Signals, Imaging, and Informatics, the third volume of the handbook, presents material from respected scientists with diverse backgrounds in biosignal processing, medical imaging, infrared imaging, and medical informatics"

"Dalam mendapatkan hasil pencitraan Kedokteran Nuklir yang baik adalah didukung dengan instrumen dengan performa yang baik yaitu sesuai dengan standar mutu alat tersebut. Untuk menjaga agar performa instrumen tetap bekerja secara optimal harus dilakukan uji secara berkala dengan protokol uji yang tepat. Penelitian ini dilakukan untuk menguji kualitas citra kamera gamma dengan fantom IEC 61675-2 dan membuat protokol pengujianya meliputi pengujian resolusi radial, resolusi tangensial dan scatter fraction. Pengujian resolusi radial dan resolusi tangensial dilakukan menggunakan sumber titik sedangkan untuk pengujian scatter fraction menggunakan sumber garis. Dari penelitian ini didapatkan hasil rerata FWHM untuk resolusi radial 14,08, pada resolusi tangensial 10,21 mm. Untuk pengujian scatter fraction didapatkan hasil 0,042 dengan prosentase hamburan 4,2%.

In order to achieve an optimal scanned image of nuclear medicine device, a good instrument with proper performance which is consistent with its standard quality is required. Furthermore, suitable and periodic protocol test is also a good requirement so that the instrument can extend its maximum performance.In order to Achieve an optimal scanned image of nuclear medicine devices, a good instrument with proper roomates performance is consistent with its standard quality is required.

This research was conducted to test the image quality of gamma cameras with phantom IEC 61675-2 and make protocol includes testing radial resolution, tangential resolution and scatter fraction. Test of tangential and radial resolution made using a point source, while for test Scatter fraction using a line source. From this research, the results of the mean FWHM for the radial resolution 14.08 mm and 10.21 mm in tangential resolution. test Scatter fraction obtained scattering percentage of 4.2%."
