Premarket evidence — what FDA accepted

Device typehardware with ml

source quote (p.3)

“AiCE is a noise reduction algorithm that improves image quality and reduces image noise by employing Deep Convolutional Neural Network methods for abdomen, pelvis, lung, and cardiac applications.”

AlgorithmDeep Convolutional Neural Network methods

source quote (p.3)

“AiCE is a noise reduction algorithm that improves image quality and reduces image noise by employing Deep Convolutional Neural Network methods for abdomen, pelvis, lung, and cardiac applications.”

Adaptive (vs locked)Yes

source quote (p.5)

“By learning to differentiate structure from noise, the algorithm produces fast, high quality CT reconstruction. The subject device has been retrained to fit for the updated/novel indications.”

PCCPFDA source did not state this

Cybersecurity addressedYes

source quote (p.8)

“Cybersecurity documentation, per the FDA cybersecurity premarket guidance document “Content of Premarket Submissions for Management of Cybersecurity in Medical Devices" issued on October 2, 2014, is also included as part of this submission.”

Reported performance (0 observations)

FDA source did not state a quantitative performance metric — non-reporting is itself the signal.

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.
