WebIn an X-ray imaging system, radiation from an X-ray source is emitted toward an object under examination, and the object is usually a patient in a medical diagnosis application. A part of the radiation passes through the object under examination and impacts a detector, which is divided into a matrix of discrete elements (e.g., pixels). Web12 de set. de 2024 · X-rays are emitted from the tungsten target. Historically, X-ray spectral lines were labeled with letters ( K, L, M, N, …). These letters correspond to the atomic shells ( n = 1, 2, 3, 4,... ). X-rays produced by a transition from any higher shell to the K ( n = 1) shell are labeled as K X-rays.

X-rays with high photon energies above 5–10 keV (below 0.2–0.1 nm wavelength) are called hard X-rays, while those with lower energy (and longer wavelength) are called soft X-rays. The intermediate range with photon energies of several keV is often referred to as tender X-rays. Due to their penetrating ability, hard X-rays are widely used to image the inside of objects (e.g. in medi… Web17 de nov. de 2014 · The inner regions of some galaxies were also found to emit X-rays.
