What is the description of computed 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 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.Sep 28, 2020.
Where does the word tomography come from?
The word tomography is derived from Ancient Greek τόμος tomos, "slice, section" and γράφω graphō, "to write" or, in this context as well, "to describe." A device used in tomography is called a tomograph, while the image produced is a tomogram..
Why is a CT important?
CT scans can be used to identify disease or injury within various regions of the body.
For example, CT has become a useful screening tool for detecting possible tumors or lesions within the abdomen.
A CT scan of the heart may be ordered when various types of heart disease or abnormalities are suspected..
Why would you need a tomography?
Why it's done.
Your doctor may recommend a CT scan to help: Diagnose muscle and bone disorders, such as bone tumors and fractures.
Pinpoint the location of a tumor, infection or blood clot.Jan 6, 2022.
- A CT of the brain is a noninvasive diagnostic imaging procedure that uses special X-rays measurements to produce horizontal, or axial, images (often called slices) of the brain.
- 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. - The CT machine passes X-ray photons through each point in the object at different angles through 360 degrees.
Fluctuations in the density of the different parts of the object change the intensity of photons that successfully pass through the object depending on the angles at which the beam of photons is shone.
