The Clinical Application of the LEBRA-PXR in Imaging Diagnosis


Article Preview

In 1895, Dr. Wilhelm Conrad Röentgen discovered the electromagnetic radiation called X-rays. Since the great finding, the applications of X-ray imaging have expanded. One of most important application is medical use, such as imaging diagnosis or radiation therapy. Also, applications of X-ray are based on the strong interactions with materials including transmission, absorption, diffraction, reflection, scattering, and emission. Today, X-ray imaging is applied to more delicate medical and life sciences, as well as basic sciences, because it is needed for its brilliance, power, and coherence. [1-6]
