What is computed tomography?

Computed Tomography is more commonly known as CT scan. It is a specialized form of X-ray. Computed Tomography is a non-invasive diagnostic procedure. CT scan provides concise images of different body parts and can also divulge any internal bleeding or injury during emergency situations. It is absolutely painless and is known to provide accurate information.

The patient is required to lie down on a table which is then passed through an opening, circular in structure. The radiations are rotated inside the CT scan machine for processing the images of the required body parts.
