Since then, technological advances and math have allowed single images to be computed into two-dimensional informative images.
The CT scan is essentially an X-ray study, where a series of rays are rotated around a specified body part, and computer-generated cross-sectional images are produced._{Jan 2, 2023}.
How many CT scans are safe per year?
There is no recommended limit on how many computed tomography (CT) scans you can have.
CT scans provide critical information.
When a severely ill patient has undergone several CT exams, the exams were important for diagnosis and treatment..
What is a CT scan NIH?
During a CT scan, the patient lies on a bed that slowly moves through the gantry while the x-ray tube rotates around the patient, shooting narrow beams of x-rays through the body.
Instead of film, CT scanners use special digital x-ray detectors, which are located directly opposite the x-ray source..
CT scan images allow the doctor to look at the inside of the body just as one would look at the inside of a loaf of bread by slicing it.
This type of special X-ray, in a sense, takes "pictures" of slices of the body so doctors can look right at the area of interest.
The conventional (traditional) CT scanner uses a fan-shaped X-ray beam, which takes a single slice image per scan and moves to the next slice scan position.
The spiral (helical) CT scanner uses a DAS in which the fan-shaped X-ray beam and detector (or multidetector) move along a helical path relative to the object.

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”—of the body.
