Achieve an optimized spectrum for dose efficiency with the Tin Filter by filtering out unnecessary photons. This delivers powerful low-dose scanning at the level of conventional X-ray examinations.
The Tin Filter cuts out lower energies to reduce dose and optimize image quality at the interface between soft tissue and air. This has direct benefits in lung and colon imaging, for example. Clinical experience also shows that Tin Filter technology reduces beam hardening artifacts and improves image quality in bony structures, making it also extremely useful in orthopedic examination.
- Optimize scans for early detection and vulnerable patients
- Provide high diagnostic confidence in lung scans1
- Enhance sensitive scans, e.g., for sinuses2 and pediatrics
- Improve spectral separation in Dual Energy scans3
Illustration of 70 kVp and 120 kVp spectra without the use of a Tin Filter, and 100 kVp and 150 kVp spectra with spectral shaping by tin (Sn) filtration (Sn100 kV and Sn150 kV, respectively). The Tin Filter reduces radiation dose by blocking low-energy X-ray photons. (Figure 1)
Comparison of image noise at the same dose (CTDIvol) for various patient diameters. Starting from approximately 20 cm, spectra with tin filtration are more dose efficient than traditional spectra. (Figure 2)
