What is a computed tomography system?
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 full name of tomography?

What is tomography also known as?
Although also based on the variable absorption of x rays by different tissues, computed tomography (CT) imaging, also known as "CAT scanning" (Computerized Axial Tomography), provides a different form of imaging known as cross-sectional imaging..
Why was CT scan called CAT scan?
CAT stands for “computed axial tomography” and CT is simply “computed tomography.” CAT scan was the first of the two terms to be used; CT scan has become more common in recent years.
These two procedures are the same, though..
- CT scans (also known as CAT scans or computed axial tomography scans) are advanced x-ray procedures.
When a person has a CT scan, they are having many x-rays taken of their body (or part of their body) at nearly the same time. - CT scans take a fast series of X-ray pictures, which are put together to create images of the area that was scanned.
An MRI uses strong magnetic fields to take pictures of the inside of the body.
CT scans are usually the first choice for imaging.
MRIs are useful for certain diseases that a CT scan cannot detect. - Medical Definition
computed tomography. noun. : a method of producing a three-dimensional image of an internal body structure by computerized combination of two-dimensional cross-sectional X-ray images. abbreviation CT. called also computed axial tomography, computerized axial tomography, computerized tomography.
