Premarket evidence — what FDA accepted
source quote (p.4)
“uCT ATLAS Astound is a computed tomography x-ray system, which is intended to produce cross-sectional images of the whole body by computer reconstruction of x-ray transmission data taken at different angles and planes. uWS-CT-Dual Energy Analysis is a post-processing software package that accepts UIH CT images acquired using different tube voltages and/or tube currents of the same anatomical location. It is an image reconstruction method for cardiac scanning based on deep learning technology.”
source quote (p.9)
“It is an image reconstruction method for cardiac scanning based on deep learning technology. It is an image reconstruction method that combines a modal-based iterative reconstruction and deep learning technology.”
