A computerized tomography (CT) scan combines a series of X-ray images taken from different angles around your body and uses computer processing to create cross-sectional images (slices) of the bones, blood vessels and soft tissues inside your body. CT scan images provide more-detailed information than plain X-rays do.

What is measure of CT?

The intensity of the attenuated X-ray beam is expressed as a CT number (also known as the linear attenuation coefficient, or attenuation value). This number is a measure of attenuation relative to air and water expressed in Hounsfield units (HU): CT number of air = -1000 HU. CT number of water = 0 HU.

What is CT in electrical?

A current transformer (CT) is a type of transformer that is used to reduce or multiply an alternating current (AC). It produces a current in its secondary which is proportional to the current in its primary.
