This review analyses the principles of detector-based spectral computed tomography and describes its common clinical applications.
- The top and bottom layers of dual-layer CT absorb low- and high-energy photons, respectively.
- Multiple spectral images are generated by projection-space decomposition.
- Spectral images can be generated in all patients scanned in this scanner.
