Premarket evidence — what FDA accepted
source quote (p.5)
“The proposed device uCT ATLAS with uWS-CT-Dual Energy Analysis includes image acquisition hardware, image acquisition, reconstruction and dual energy analysis software, and associated accessories. The new generation reconstruction method, Deep IR (also named AIIR), which combines the model-based iterative reconstruction and deep learning technology together, in order to reduce image noise and artifacts, while at the same time improving low contrast detectability and spatial resolution”

“The new generation reconstruction method, Deep IR (also named AIIR), which combines the model-based iterative reconstruction and deep learning technology together, in order to reduce image noise and artifacts, while at the same time improving low contrast detectability and spatial resolution. It is an image reconstruction method that combines a modal-based iterative reconstruction and deep learning technology. Dedicated deep neural network (DNN) which is trained on low dose FBP images to get normal dose (high quality) FBP images”
