Book excerpt: Seminar paper from the year 2011 in the subject Medicine - Other, grade: 1,3, University of Applied Sciences Ulm (Informatik), course: Medizinische Bildverarbeitung, language: English, abstract: This paper introduces into the essentials of computed tomography and gives a brief lead-in to Cardiac CT, which is the clinical application of computed tomography in cardiac imaging. At first, the usage of X-rays is explained and the resulting main task of a CT scanner: The reconstruction of a three-dimensional image from the X-ray shadows, that are captured by the digital radiation detector unit. This reconstruction problem is known as the inverse problem in mathematics, which was initially solved by Johann Radon. Transferred to the field of computed tomography, the inverse problem means the definition of a volume dataset by reconstruction algorithms like for instance the Fourier Transform, which is shortly introduced, as well as the filtered backprojection. The main issue of Cardiac CT is the steady movement of the heart and chest of an examined patient. To ensure high image quality the scanner is triggered by a concurrently recorded ECG. ECG Triggering can ensure that the scanner only captues images during the phases of the heartbeat, where movement is minimal. One major application of Cardiac CT is non-invasive coronary angiography, which possibly could substitute invasive diagnostic surgeries like cardiac catheterization of non-emergency patients.

Download or read book Dual Energy CT in Cardiovascular Imaging written by Patricia M. Carrascosa and published by Springer. This book was released on 2015-10-03 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first textbook in DECT focussing especially on the cardiovascular field. DECT was developed many years ago but has recently spread its clinical utility. Many new applications have been developed over the last years and the cardiovascular system has benefited from these advances. New protocols will be used in the near future which will help to optimize results obtained until now with single energy CT, such as a more precise quantification of coronary artery stenosis using either different monochromatic levels or material decomposition, reduction of beam hardening artifacts in perfusion studies and optimizing endovenous contrast, among others.
Download or read book Computed Tomography Principles Techniques and Clinical Applications written by Robert Meyer and published by American Medical Publishers. This book was released on 2021-11-16 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computed tomography is an imaging procedure that makes use of computer-processed combinations of many X-ray measurements. The X-ray measurements are taken from different angles to produce cross-sectional images of particular areas of a scanned object. This helps in seeing inside the object without cutting. Computed tomography is an important tool in medical imaging which supplements medical ultrasonography and X-rays. It is primarily used for preventive medicine or screening for disease, such as CT scanning of head, lungs, angiography, etc. CT scanning of the head is used to detect medical conditions such as bone trauma, tumors, infarction and calcifications. CT scanning of lungs is used for detecting both acute and chronic changes in the lungs parenchyma. In angiography, it is used to visualize arterial and venous vessels throughout the body. In cardiac imaging, it is performed to gain knowledge about cardiac and coronary anatomy. This book unravels the recent studies in the field of computed tomography. The topics covered herein deal with the core aspects of this field. This book will prove to be immensely beneficial to students and researchers in medical imaging.
