What is a computer tomography?
The term “computed tomography,” or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine's computer to generate cross-sectional images, or “slices.”.

What is the description of computed tomography?
Computed tomography (CT), sometimes called "computerized tomography" or "computed axial tomography" (CAT), is a noninvasive medical examination or procedure that uses specialized X-ray equipment to produce cross-sectional images of the body..
Where is a tomography used?
A CT scan can show detailed images of any part of the body, including the bones, muscles, organs and blood vessels.
CT scans can also be used for fluid or tissue biopsies, or as part of preparation for surgery or treatment..
- A CT image consists of an array of picture elements called pixels.
Each pixel represents the mean attenuation of an axial column of tissue about 1 cm in length.
The attenuation is expressed as a Hounsfield number.
