How it works?

What type of images does a CT scanner provide?

• Low-resolution anatomical images

• High-resolution cross-sectional anatomical images

• 3D animated images

• Only bone images

The table moves through a circular opening in the CT scanner called the ________, while an x-ray tube emits x-rays as it spins 360 degrees inside the gantry.

• gantry

• aperture

• collimator

• detector

What does a detector array measure in a CT scanner?

• The amount of x-rays that pass through the anatomic part

• The speed of the table

• The temperature inside the scanner

• The color of the images

In which year was the CT scan invented?

• 1960

• 1972

A CT scan is mainly used for:

• Cooking

• Medical imaging and diagnosis

• Painting

• Construction

Instead of sending out a single X-ray through the body as with ordinary x-ray, what does a CT scan do?

• Several beams are sent at the same time from different angles.

• It uses only sound waves to create images.

• It only measures the temperature of the body.

• It produces images using magnetic fields only.
