| Abstract: | Single Energy CT • Single energy CT is comprised of a single spectrum with photon energies roughly between 70 and 140kV. • X-rays are emitted from a single source (one x-ray tube) and are detected by one bank of detectors • The inherent contrast of the image dataset depends on differences in photon attenuation of the various materials that constitute the human body (air, calcium, fat, …) • The amount of attenuation is dependent on: • Tissue composition • photon energy and how closely it exceeds the K-edge • Therefore, tissue attenuation can be manipulated by changing photon energy levels. |
