What is a CT Scanner and How Does It Work?
CT (Computed Tomography) scanner is an advanced medical device that makes use of x-rays in order to generate detailed cross-sectional images of the inside of the body. An X-ray tube that goes around the patient emits X-ray beams as the table slides through the scanner. These beams go through the body where they are absorbed at different rates based on how dense the tissues are. The detector arrays on the opposite side collect these X-rays after leaving one’s body and a computer processes them into a series of two dimensional pictures known as “slices”. These slices can be combined further to form a complete three-dimensional model that allows for anatomical and pathological studies with high precision. CT scanners have become integral tools in diagnostic medicine because of their capacity to produce high-resolution images with improved contrast.
