How do CT scans work? Understanding the intricacies of CT scan technology sheds light on its remarkable diagnostic capabilities and medical applications.
Here are the steps involved in a CT scan how it works: The patient is placed on a motorized table that moves them into the CT scanner. A computer then compiles this information to create an image or series of images displaying different layers of tissue within the body.
At the heart of a CT scan machine is a rotating X-ray tube that emits a narrow beam of radiation. As the tube rotates around the patient, sensors capture the X-rays that pass through the body, producing signals that a computer then transforms into images.
