How does a CT machine work?
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 are the advantages of Computerised tomography?
When used appropriately, the benefits of a CT scan far exceed the risks.
CT scans can provide detailed information to diagnose, plan treatment for, and evaluate many conditions in adults and children.
Additionally, the detailed images provided by CT scans may eliminate the need for exploratory surgery.May 1, 2023.

What are the tools required for conducting a CT scan?
Filter.
The filter stays between the patient and the source of the x-ray. Collimator.
Another tool used in the CT scan is the collimator. Detector array.
Now, the detector array is one of the most functional parts of a CT scan. Gantry..What does a computed tomography do?
Computed tomography is commonly referred to as a CT scan.
A CT scan is a diagnostic imaging procedure that uses a combination of X-rays and computer technology to produce images of the inside of the body.
It shows detailed images of any part of the body, including the bones, muscles, fat, organs and blood vessels..
What equipment is used for computed tomography?
The CT scanner is typically a large, donut-shaped machine with a short tunnel in the center.
You will lie on a narrow table that slides in and out of this short tunnel.
Rotating around you, the x-ray tube and electronic x-ray detectors are located opposite each other in a ring, called a gantry..

What is the device used in tomography?
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..

Filter.
The filter stays between the patient and the source of the x-ray. Collimator.
Another tool used in the CT scan is the collimator. Detector array.
Now, the detector array is one of the most functional parts of a CT scan. Gantry.- CT scanners are composed of three important elements: an X-ray tube, a gantry with a ring of X-ray sensitive detectors, and a computer.
In this method, images are created using the same physics principles as in conventional radiography. - Unlike x-ray radiography, the detectors of the CT scanner do not produce an image.
They measure the transmission of a thin beam (1-10 mm) of x-rays through a full CT of the body.
The image of that section is taken from different angles, and this allows to retrieve the information on the depth (in the third dimension).
