CAT scans take the idea of conventional X-ray imaging to a new level. Instead of finding the outline of bones and organs, a CAT scan machine forms a full three-dimensional computer model of a patient's insides. Doctors can even examine the body one narrow slice at a time to pinpoint specific areas.


A CT scanner emits a series of narrow beams through the human body as it moves through an arc. This is different from an X-ray machine, which sends just one radiation beam.


How Does a CAT Scan Machine Work? According to the FDA, CAT scans rotate an x-ray source mounted opposite a detector around a patient, producing a thin, fan-shaped beam of x-rays that pass through patients' bodies one small section at a time.


A CT scan machine works by emitting multiple beams of radiation through the body and uses digital geometry processing to create detailed pictures, explains Medical News Today.


Computed tomography, more commonly known as a CT or CAT scan, is a diagnostic medical test that, like traditional x-rays, produces multiple images or pictures of the inside of the body. The cross-sectional images generated during a CT scan can be reformatted in multiple planes, and can even generate three-dimensional images.


How Does an MRI Scan Work? MRI stands for Magnetic Resonance Imaging. MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce images of your organs, soft tissue, bone and internal structures. As a patient, you’ll lie on a table that will slide into the machine. ... CT is an X-ray machine that’s hooked up to a ...


Computerized axial tomography (CAT) scan machines produce X-rays, a powerful form of electromagnetic energy.X-ray photons are basically the same thing as visible light photons, but they have much more energy. This higher energy level allows X-ray beams to pass straight through most of the soft material in the human body.


Source: Terese Winslow. The term “computed tomography”, or CT, refers to a computerized x-ray imaging procedure in which a narrow beam of x-rays is aimed at a patient and quickly rotated around the body, producing signals that are processed by the machine’s computer to generate cross-sectional images—or “slices”—of the body.
