Interlaced R2D2 DNN series enhances scalable MRI reconstruction with self-calibration

Researchers have developed a new deep neural network series called interlaced R2D2 (iR2D2) designed for scalable image reconstruction in non-Cartesian MRI scans. This approach addresses limitations in training large-scale unrolled DNN architectures by adapting a residual estimation paradigm from radio astronomy. The iR2D2 framework iteratively refines image reconstruction while simultaneously self-calibrating sensitivity maps, improving accuracy and performance over existing methods. AI
