WebX-rays for CT scans are made in two ways. One way involves an electron slowing down as it travels around an atom. The energy that is lost when the electron loses its momentum forms an X-ray. This is called “bremsstrahlung”, from the German word for ‘braking radiation’. The bremsstrahlung x-rays wavelength can vary over the x-ray spectrum. WebX-rays for CT scans are made in two ways.
