X-rays transmit electromagnetic radiation with wavelengths between 0.01-10nm with frequencies between 30 X 1016 Hertz to 30 X 1019 Hertz.
The magnetic radiation is generated in vacuum tubes by bombarding a metal target with high-speed electrons after passing through the imaging patients’ body and the resulting radiation is recorded on to a photographic plate or digital recorder producing a radiographic image.
If the source and the detector rotate around the patient’s body a “slice” image is created and captured and is referred to as computerised tomography (CT).
