Computed Tomography Can Produce Clear Images of the Whole Body
Computed tomography (CT) refers to the minimally invasive medical imaging of the body that helps physicians to diagnose and treat certain medical conditions. CT scan is also known as computed axial tomography (CAT) scan. This medical test involves detailed images of the patient’s body with aid of advanced X-ray technology.
CT scanner can produce the images of the person to be examined for the oncology procedures. These images are of great help to the doctors to examine the current condition of the patients. The computed tomography of body can be related to the heart, liver, lungs, kidney, arteries, bones, etc. This technology can be done on whole body or just some parts of it. The computed tomography angiography uses contrast material that can be injected into a peripheral vain to generate detailed images of both blood vessels and tissues. Digital geometry processing is used to produce three-dimensional (3D) image of the inside of the body or object from a large series of two dimensional X-ray images taken around a single axis of rotation.
A volume of data, generated by the CT procedure, can be manipulated through windowing in order to view bodily structures. There are two types of CT scans, such as screening CT scan and diagnostic CT scan. It has become an important tool of medical imaging to supplement X-rays and medical ultrasonography. The CT colonography is a full-motion heart scan for patient with high risk of heart disease. Computed tomography technology for body scanning is used to detect both acute and chronic changes in the lung. CT scanner looks a large, box like machine with a hole or short tunnel.
