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. WebOptical coherence tomography (OCT) is an imaging technique that uses low-coherence light to capture micrometer-resolution, two- and three-dimensional images from within optical scattering media (e.g., biological tissue). It is used for medical imaging and industrial nondestructive testing (NDT). Optical coherence tomography is based on low …
