Building on the success of Sonic DL™ for Cine imaging in cardiac MR, GE HealthCare is introducing Sonic DL for 3D‡ MR sequence. Sonic DL is a deep-learning-based image acquisition acceleration technique that will be available for use on GE HealthCare 1.5T, 3.0T, and 7.0T* MR systems. Sonic DL reconstructs MR images from highly undersampled data, and thereby enables acceleration factors up to 12 times compared to fully sampled datasets—an 86% reduction in scan time versus a fully sampled acquisition. Its underlying technology is a Convolutional Neural Network (CNN) powered iterative reconstruction technique for vastly under-sampled data.
When compared to equivalently under-sampled—but conventionally reconstructed data—Sonic DL images will demonstrate image quality approaching that of a fully sampled dataset. When used in sequences while holding time constant, Sonic DL can decrease the acquired voxel size, enabling resolution improvement. Images acquired with Sonic DL can be reconstructed with AIR™ Recon DL‡‡ to further improve image quality by removing noise and ringing.
