A CT scan is an advanced x-ray procedure that produces detailed cross-sectional images using computer processing. Unlike conventional x-rays, which use a fixed tube, CT scanners employ a motorized x-ray source that rotates around the patient, capturing images from multiple angles. These images are collected by digital detectors and processed by a computer to create either two-dimensional slices or three-dimensional images. This technology allows for the visualization of bones, soft tissues, and organs, aiding physicians in diagnosing abnormalities and planning treatments.
