A CT scan, also called X-ray computed tomography (X-ray CT) or computerized axial tomography scan (CAT scan), makes use of computer-processed combinations of many X-ray images taken from different angles to produce cross-sectional (tomographic) images (virtual 'slices') of specific areas of a scanned object, allowing the user to see inside the object without cutting.
Digital geometry processing is used to generate a three-dimensional image of the inside of the object from a large series of two-dimensional radiographic images taken around a single axis of rotation.Medical imaging is the most common application of X-ray CT. Its cross-sectional images are used for diagnostic and therapeutic purposes in various medical disciplines. The rest of this article discusses medical-imaging X-ray CT; industrial applications of X-ray CT are discussed at industrial computed tomography scanning.
As X-ray CT is the most common form of CT in medicine and various other contexts, the term computed tomography alone (or CT) is often used to refer to X-ray CT, although other types exist (such as positron emission tomography [PET] and single-photon emission computed tomography [SPECT]). Older and less preferred terms that also refer to X-ray CT are computed axial tomography (CAT scan) and computer-aided/assisted tomography. X-ray CT is a form of radiography, although the word "radiography" used alone usually refers, by wide convention, to non-tomographic radiography.
NIBIB's 60 Seconds of Science explains how CT scans work. CT images are more detailed than conventional x-ray images. Image slices that CT scans produce can be 2 or 3 dimensional and can reveal abnormal structures or help the physician plan and monitor treatments. Music by longzijun 'Chillvolution.'

A CT scan takes a series of X-rays and uses a computer to put them together. It helps your doctor make a diagnosis, decide about what treatment you need or find out if your treatment is working. Find out what happens when you have the scan. This is a Cancer Research UK video.

Computed Tomography (CT) is a scanning technique that uses X-Rays to take highly detailed images of the body. A CT scan can give detailed information about many parts of the body, including the lungs, bones, soft tissues, heart and blood vessels. It can be used to diagnose and monitor many conditions.
Reading a CT scan in a systematic way in the Emergency Department can help you quickly and thoroughly assess for any neurological pathology. Remember the mnemonic "Blood Can Be Very Bad"

This is what a ct scanner looks like on the inside while it spins like a mad man.
In this video, I try to explain the basic principle of how Computed Tomography (Cat Scan) works. We also take a look inside the gantry and console of the system and see the machine take a scan of a phantom (no, we didn't radiate a person for this!!). I tried to keep this as non-technical as possible. Enjoy!

What is CT? Computed Tomography, known as CT or a CAT scan, uses X-ray images to produce a three-dimensional image of your body. It produces a more detailed image than conventional x-ray. CT imaging is used to show more detail of soft tissue, like the brain, as well as dense tissue, like bone. Multiple CT images are stacked like slices of a loaf of bread. A "contrast" is used in CT: CT scans often require the use of a liquid to help see the body and its organs and any abnormalities better. It is called "contrast." You may drink the special liquid or have it injected. The contrast will be removed from your body through normal urination and bowel movements.

This video deals with the anatomy of the thorax in transverse anatomical and axial CT sections. The video begins with a transverse anatomical section at the root of the neck and continues down to the level of T10 vertebra where the esophagus passes through the diaphragm. The anatomical sections are arranged to match CT & MRI sections to provide better understanding of the imaging anatomy of the thorax. The arrangement of thoracic structures is followed in (17) serial transverse sections of the thorax and compared with (11) representative axial CT sections at different levels. The anatomical sections are selected from the Visible Human Project.
