How does multislice CT work?

Multi-Slice CT Scanners When a patient passes through the CT, the circular opening rotates and takes a series of x-rays. Each rotation takes approximately 1 second. During the rotation, beams of radiation are used to make an image of the particular section of the patient’s body inside the circular opening.

What is a 64 slice CT?

Like a traditional computed tomography (CT) scan, our 64-slice CT scan combines a series of X-ray views taken from many different angles, and then uses a computer to reconstruct the “slices” to produce actual pictures.
