| ct scan new technology: Health Risks from Exposure to Low Levels of Ionizing Radiation Committee to Assess Health Risks from Exposure to Low Levels of Ionizing Radiation, National Research Council, 2006-03-23 This book is the seventh in a series of titles from the National Research Council that addresses the effects of exposure to low dose LET (Linear Energy Transfer) ionizing radiation and human health. Updating information previously presented in the 1990 publication, Health Effects of Exposure to Low Levels of Ionizing Radiation: BEIR V, this book draws upon new data in both epidemiologic and experimental research. Ionizing radiation arises from both natural and man-made sources and at very high doses can produce damaging effects in human tissue that can be evident within days after exposure. However, it is the low-dose exposures that are the focus of this book. So-called “late” effects, such as cancer, are produced many years after the initial exposure. This book is among the first of its kind to include detailed risk estimates for cancer incidence in addition to cancer mortality. BEIR VII offers a full review of the available biological, biophysical, and epidemiological literature since the last BEIR report on the subject and develops the most up-to-date and comprehensive risk estimates for cancer and other health effects from exposure to low-level ionizing radiation. |
| ct scan new technology: Branching and Rooting Out with a CT Scanner: The Why, the How, and the Outcomes, Present and Possibly Future Pierre Dutilleul, Jonathan A. Lafond, 2016-04-13 Until recently, a majority of the applications of X-ray computed tomography (CT) scanning in plant sciences remained descriptive; some included a quantification of the plant materials when the root-soil isolation or branch-leaf separation was satisfactory; and a few involved the modeling of plant biology processes or the assessment of treatment or disease effects on plant biomass and structures during growth. In the last decade, repeated CT scanning of the same plants was reported in an increasing number of studies in which moderate doses of X-rays had been used. Besides the general objectives of Frontiers in Plant Science research topics, “Branching and Rooting Out with a CT Scanner” was proposed to meet specific objectives: (i) providing a non-technical update on knowledge about the application of CT scanning technology to plants, starting with the type of CT scanning data collected (CT images vs. CT numbers) and their processing in the graphical and numerical approaches; (ii) drawing the limits of the CT scanning approach, which because it is based on material density can distinguish materials with contrasting or moderately overlapping densities (e.g., branches vs. leaves, roots vs. non-organic soils) but not the others (e.g., roots vs. organic soils); (iii) explaining with a sufficient level of detail the main procedures used for graphical, quantitative and statistical analyses of plant CT scanning data, including fractal complexity measures and statistics appropriate for repeated plant CT scanning, in experiments where the research hypotheses are about biological processes such as light interception by canopies, root disease development and plant growth under stress conditions; (iv) comparing plant CT scanning with an alternative technology that applies to plants, such as the phenomics platforms which target leaf canopies; and (v) providing current and potential users of plant CT scanning with up-to-date information and exhaustive documentation, including clear perspectives and well-defined goals for the future, for them to be even more efficient or most efficient from start in their research work. |

| ct scan new technology: Spectral, Photon Counting Computed Tomography Katsuyuki Taguchi, Ira Blevis, Krzysztof Iniewski, 2020-07-14 Spectral, Photon Counting Computed Tomography is a comprehensive cover of the latest developments in the most prevalent imaging modality (x-ray computed tomography (CT)) in its latest incarnation: Spectral, Dual-Energy, and Photon Counting CT. Disadvantages of the conventional single-energy technique used by CT technology are that different materials cannot be distinguished and that the noise is larger. To address these problems, a novel spectral CT concept has been proposed. Spectral Dual-Energy CT (DE-CT) acquires two sets of spectral data, and Spectral Photon Counting CT (PC-CT) detects energy of x-ray photons to reveal additional material information of objects by using novel energy-sensitive, photon-counting detectors. The K-edge imaging may be a gateway for functional or molecular CT. The book covers detectors and electronics, image reconstruction methods, image quality assessments, a simulation tool, nanoparticle contrast agents, and clinical applications for spectral CT. |

| ct scan new technology: Computed Tomography Stewart C. Bushong, 2000-05-25 Here's everything students must know about computed tomography to excel in the classroom, score big on the ARRT exams, and thrive in clinical practice. Covers the full range of topics--ultrasound interaction with tissue, the ultrasound beam and image, quality control, the biological effects of ultrasound, image artifacts, and more. |
| ct scan new technology: Clinical Applications of SPECT/CT International Atomic Energy Agency, 2008 Integrated single photon emission computed tomography and computed tomography (SPECT/CT) has emerged as an important diagnostic tool in medical imaging, where morphological markers are superimposed on anatomical images to allow a more thorough examination and higher levels of diagnostic accuracy. This TECDOC presents an overview of the SPECT/CT technology for use by nuclear medicine physicians, radiologists and clinical practitioners. The publication also covers the current medical status of SPECT/CT imaging, the role of this technology in the clinical management of patients and possible trends for future development. |
| ct scan new technology: Technical Fundamentals of Radiology and CT Guillermo Avendaño Cervantes, 2016 Technical Fundamentals of Radiology and CT is intended to cover all issues related to radiology and computed tomography, from the technological point of view, both for understanding the operation of all devices involved and for their maintenance. It is intended for students and a wide range of professionals working in various fields of radiology, those who take images and know little about the workings of the devices, and professionals who install, maintain and solve technological problems of all radiological systems used in health institutions. |
