Premarket evidence — what FDA accepted

Device typesamd

source quote (p.5)

“Al-Rad Companion (Musculoskeletal) is software-only image post-processing application that uses deep learning algorithms to post-process CT data of the thorax.”

Algorithmdeep learning algorithms, 3D Deep Image-to-Image network, convolutional encoder-decoder

source quote (p.5)

“Al-Rad Companion (Musculoskeletal) uses the same deep learning technology as in the previously cleared reference device Siemens Al-Rad Companion (Cardiovascular) (K183268). More precisely, a 3D Deep Image-to-Image network is used for organ segmentation. The main structure of the network is designed following a symmetric way as a convolutional encoder-decoder. All blocks of the network consist of 3D convolutional and bilinear upscaling layers.”

Cybersecurity addressedYes

source quote (p.9)

“Siemens conforms to the cybersecurity requirements by implementing a process of preventing unauthorized access, modifications, misuse or denial of use, or the unauthorized use of information that is stored, accessed or transferred from a medical device to an external recipient. Provided in this submission is a cybersecurity statement that considers IEC 80001-1:2010. The responsibility for compliance with IEC 80001-1-2010 is the hospital.”

Reported performance (0 observations)

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