Do CT scans have films?
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..
How CT films are stored?
To store such a large volume of medical images, each hospital usually has a PACS server.
PACS (Picture Archiving and Communication System) is a central server on which images are stored, and from which they can be retrieved when needed..
How do you study for a CT scan film?
In order to read a CT scan, you must consider the colors white, gray, and black.
Each color represents a distinct part of your body: soft tissues, fat, air, and bone.
A change in color in a specific area of your body might indicate the presence of an abnormality.
Dense tissues, such as bone, are seen as white patches..
What is CT film?
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..
Why are CT images helpful?
A CT scan can be used to visualize nearly all parts of the body and is used to diagnose disease or injury as well as to plan medical, surgical or radiation treatment..
Why are CT scans sometimes used instead of radiography?
A CT scan, or computed tomography scan, sends radiation through the body.
However, unlike a simple X-ray study, it offers a much higher level of detail, creating computerized, 360-degree views of the body's structures.
CT scans are fast and detailed.
They take longer than X-rays but are still fast (about one minute)..
- Typical matrix size for CT scanners is 512 \xd7 512 pixels, or more than 260,000 pixels comprising the image.
Because CT acquires tomographic slices, each pixel actually represents a small volume of tissue, a voxel.
