It can depict the severity, level and cause of obstruction. Introduction. Introduction Computed tomography (CT) is an imaging technique that makes it possible to visualize the internals of an object (in-cluding the human body) from a limited number of lower-dimensional projections. Multi-Detector row Computed Tomography is an important imaging modality for characterization and presurgical evaluation of neck masses. 1. Unlike conventional radiography which uses a fixed X-ray tube, computed tomography utilizes a motorized X-ray source that rotates 3600 around The smooth, continuous curve is due to Bremsstrahlung radiation, and the spikes are characteristic K lines for rhodium atoms [Source: Wikipedia]. • Digital geometry processing is used to generate three-dimensional images of the object from those slices. Since its introduction in the 1970s, computed tomography (CT) has revolutionized diagnostic decision making[1,2].It has resulted in better surgery, better diagnosis and treatment of cancer, better treatment after injury and major trauma, Helical scanning and the invention of multiple detectors are just a couple.

In our hospital, emergency physicians (EPs) must interpret emergency CT scans and formulate a plan for managing most trauma cases. Introduction Computed Tomography (CT) was introduced into clinical practice in 1972 and revolutionized X Ray imaging by providing high quality images which reproduced transverse cross sections of the body. X-ray scans furnish detailed images of an object such as dimensions, shape, internal defects and some pathology can be seen in … Since its introduction in the 1970s, computed tomography (CT) has revolutionized diagnostic decision making[1,2].It has resulted in better surgery, better diagnosis and treatment of cancer, better treatment after injury and major trauma, Introduction Computed Tomography (CT) was first introduced as a medical device in the 1970's, and has since become a ubiquitous imaging tool. CT could be an ideal tool to study representative sizes of soil samples because of the noninvasive characteristic of this technique. Any deadline is manageable when you have so proficient writers on the team. Computed tomography (CT) imaging contributes up to 63% of the patients' collective doses from medical exposure, leading to a significant increase in cancer incidence up to 2% (Mettler et al.,2020; Marant-Micallef et al., 2019; Brenner &Hall, 2007). Introduction. Computerized tomography is believed to be the most important development in diagnostic imaging history since the discovery of X rays in 1895 by W. K. Roentgen. 1. Computed tomography (CT) has been used as a non-invasive tomographic method in a wide range of applications from medical diagnosis to astronomy [1-6]. Our aim is to propose the split-bolus multidetector-row computed tomography technique as an alternative to the Introduction: Computed tomography (CT) from penetrating radiation allows one to reconstruct the inte-rior structure of an object without physically dissecting it. Computed tomography (CT) was introduced in the early 1970s and has since then revolutionized diagnostic radiology. We calculate the annual net profits from CT introduction in Japan for single-slice CT (SSCT), multi-slice CT (MSCT), number of hospital beds, and prefecture.
