Facilitating screening by enabling significantly lower radiation dose.

In conventional CT imaging, two low energy photons contribute to the image the same way as one high-energy photon. In reality, the low energy photons carry more information of body tissue contrasts, as well as more statistical information from their exact number. In conventional CT imaging, this information is lost.

In SPCCT this information is maintained. Reduced dose scanning procedures can be offered to a larger population with a wider class of indications.

For example combined Calcium scoring and lung screening with improved image quality and tomographic background removal is expected to be widely possible with doses around and potentially below 1 mSv.
