Computed tomography variables

What are the main components of computed tomography?

Therefore, hardware elements are discussed first.

What are the main components of computed tomography?

A CT scan can show detailed images of any part of the body, including the bones, muscles, organs and blood vessels.
CT scans can also be used for fluid or tissue biopsies, or as part of preparation for surgery or treatment..

What are the main concepts of computed tomography?

Hounsfield units (HU) are used in computed tomography (CT) to represent CT numbers in a standardised format of the resultant image.
HU is derived from a linear transformation of the measured attenuation coefficients based on arbitrarily assigned air and pure water densities..

What are the parameters of CT machine?

The major technical parameters that we will discuss are: tube current (mA), rotation time (s), tube potential (kVp) and helical pitch..

What does computed tomography measure?

During a CT scan, the patient lies on a bed that slowly moves through the gantry while the x-ray tube rotates around the patient, shooting narrow beams of x-rays through the body.
Instead of film, CT scanners use special digital x-ray detectors, which are located directly opposite the x-ray source..
