Premarket evidence — what FDA accepted
source quote (p.4)
“Neurophet AQUA is a fully automated MR imaging post-processing medical device software that provides automatic labeling, visualization, and volumetric quantification of brain structures from a set of MR images and returns segmented images and morphometric reports.”
source quote (p.8)
“Although both are technically similar, in the processing architecture, the subject device performs segmentation based on deep learning and the predicate device performs segmentation based on atlas-based.”
Validation studies (2)
Retrospective clinical
n=64 scans
endpoints: segmentation accuracy
Bench
n=50 scans
