How a CT works
A CT scanner is one of the most powerful diagnostic tools available to medical practitioners. A CT scan produces 3D images of organs such as the head, heart or lungs, and with a high contrast ratio between bone, tissue, blood vessels and other parts of the body.
So how does a CT scanner work? This simple description of the operation of a CT scanner explains how the machine captures multiple image ‘slices’ by detecting X-ray pulses passing through the patient’s body, and then compiles the slices in software to render an image that the physician can view and analyze.
It also shows how critical components such as the readout IC affect the resolution and quality of the image and the radiation dosage to which the patient is exposed.
