Dynamic UNIQUE’s inter-frame (temporal) noise suppression uses temporal averaging, which accumulates the dose of successive frames, to reduce noise in static anatomical structures. When movement is detected, temporal averaging is restrained and spatial noise suppression steps in.
In moving regions, Dynamic UNIQUE applies intra-frame (spatial) noise suppression. The strength of spatial noise suppression is adapted to the strength of temporal noise reduction. As a result, image noise level is kept consistently low over the entire image
