How are CT scans made?
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 components of CT scan?
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..

What are the components of computed tomography?
A CT scan can show detailed images of any part of the body, including the bones, muscles, organs and blood vessels.
CT scans can also be used for fluid or tissue biopsies, or as part of preparation for surgery or treatment..
What are the components of 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 are the main concepts of computed tomography?
The imaging group contains all of the elements necessary to produce an image, including the x-ray generator, x-ray tube, and detector system.
The generator, x-ray tube(s) and detector(s) are located in housing called a gantry (Fig. 9-9), which also contains the mechanics that provide the motion used in the CT unit..
What are the three primary components of a computed tomographic system?
The imaging group contains all of the elements necessary to produce an image, including the x-ray generator, x-ray tube, and detector system.

What does a CT consist of?
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?
Individual detector elements are affixed to a circuit board.
Solid state crystal detectors are made from a variety of materials, like cadmium tungstate, cesium iodide, bismuth germinate and ceramic rare earth compounds like gadolinium of yttrius..
What equipment is used in computed tomography?
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..Why do we need computed tomography?
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..
