Problem the AI is intended to solve

The software used on the proposed SIGNA Artist system has been modified to include the AIR Recon DL feature. The User interface provides operators of the system with new options for selecting AIR Recon DL and adjusting the associated level of image noise reduction. The resulting images can have higher Signal to Noise Ratio (SNR) and improved sharpness compared to images reconstructed without AIR Recon DL.

Expected benefits

The nonclinical testing demonstrated that AIR Recon DL does improve SNR and image sharpness while maintaining low contrast detectability and having minimal impacts to noise spectral content, average signal intensity, or the appearance of motion artifacts. AIR Recon DL was also able to maintain image SNR and did not sacrifice sharpness for images acquired with a reduced scan time. The nonclinical testing passed the defined acceptance criteria, and did not identify any adverse impacts to image quality or other concerns related to safety and performance.

System outputs

Denoised images. The images produced by the SIGNA Artist system reflect the spatial distribution or molecular environment of nuclei exhibiting magnetic resonance.
