GhariebLondon :IntechOpen,2022.©20221 online resource (86 pages)1-80355-119-4 Includes bibliographical references and index.A computed tomography (CT) scan uses X-rays and a computer to create detailed images of the inside of the body. CT scanners measure, versus different angles, X-ray attenuations when passing through different tissues inside the body through rotation of both X-ray tube and a row of X-ray detectors placed in the gantry. These measurements are then processed using computer algorithms to reconstruct tomographic (cross-sectional) images. CT can produce detailed images of many structures inside the body, including the internal organs, blood vessels, and bones. This book presents a comprehensive overview of CT scanning. Chapters address such topics as instrumental basics, CT imaging in coronavirus, radiation and risk assessment in chest imaging, positron emission tomography (PET), and feature extraction.Computed-Tomography TomographyTomography.616.0757Gharieb Reda R.NjHacINjHaclBOOK9910688362403321Computed-Tomography (CT) Scan2903072UNINA00477nam 2200181z- 450 99110349776033211-04-078543-3(CKB)4100000012907570(EXLCZ)99410000001290757020251012c2013uuuu -u- -engAfter the Break: Television Theory TodayTaylor & Francis LtdAfter the BreakBOOK9911034977603321After the Break1803267UNINA
