Sonic DL is a software feature by GE Healthcare that uses deep learning to reconstruct cardiac MR images much faster by processing under-sampled data. It allows highly accelerated imaging with preserved image quality, enabling faster and more efficient MRI scans for cardiac assessment in patients of all ages.
Intended Use
Sonic DL is a Deep Learning based image reconstruction technique that is available for use on GE Healthcare 1.5T and 3.0T MR systems. Sonic DL reconstructs MR images from highly under-sampled data, and thereby enables highly accelerated acquisitions. Sonic DL is intended for cardiac imaging, and for patients of all ages.
Technology
Sonic DL is a deep learning based reconstruction algorithm integrated into GE Healthcare MR systems. It improves the speed of cardiac cine MR imaging by enabling acceleration factors as high as 12 and allows single heartbeat imaging with breath holds or free breathing, surpassing conventional parallel imaging acceleration techniques.
Performance
Nonclinical testing using simulated MR phantoms demonstrated that Sonic DL reconstructs images comparable in quality and temporal sharpness to fully sampled cine images. Clinical testing involving radiologists showed that functional cardiac measurements from Sonic DL images had less variability compared to conventional methods and that the images were of diagnostic quality with significantly reduced scan times. Additionally, Sonic DL supports free-breathing single heartbeat imaging showing good agreement with conventional measurements.
