What are CT scanning slices?

Scanning of computer tomography (CT) is a medical technique that provides images of internal organs and bones of the body. It does this by taking X -ray images of the body in many different directions to make many pictures in thin slices. The machine collects all these slices of CT scanning into a complex image for a physician, who can use the symptoms of the disease in the patient. Medical problems such as cancer, internal injuries and blockages can be diagnosed with this technique.

Older medical display techniques, such as simple X -rays, have a limit that they can only look directly through the body. However, slices of CT scan look one piece at the body at a time, similar to slices of loaf bread; In fact, the CT scanner takes these images in different directions, not only vertically, it requires the machine to worry about a studied person, and the patient must lie inside the machine, turning around the person to create CT scanning from all directions.

vertical scanning slices CT persons are equivalent to slices of bread, while other directional slices are like cutting a loaf at a more clever angle. Each of the CT scanning cuts is produced by X -ray rays moving body and landing on X -ray detectors on the opposite side of the machine. The speed at which X -rays move through the body concerns the type of substance in the way, and therefore a dense bone in the X -ray image appears white. In the resulting image, less dense organs look, while the air seems black.

Medical science has gathered information about CT scan sheets and the normal appearance of healthy parts of the body. If the body is ill or injured, it may look unusual when scanning, which can help doctors to determine the cause of the health problem. Sometimes the patient must receive or be injected before scanning to make the resulting images clarify. This is particularly useful in the diagnosis of probesLames such as a blocked blood vessel or pipes inside the body.

CT scan uses radiation to create images associated with cancer development, but the amount of radiation used is very unlikely to cause cancer. Since growing children and unborn children are more sensitive to radiation, pregnant women and children can be inappropriate candidates for scanning CT. The advantages of CT scans over other diagnostic methods such as exploratory surgery include their overall safety, the absence of any recovery time and easy use.
