MRI Reconstruction With Deep Learning

Researchers have developed a deep learning platform to speed up the MRI reconstruction process. The framework takes a fraction of the measurements that the traditional technique would use. It uses plug-and-play algorithms to combine physics-driven data acquisition models with state-of-the-art learned image models. The plug-and-play techniques recover pictures faster, with improved quality and potentially superior diagnostic utility than existing MRI reconstruction methods. The researchers also used deep learning-based denoisers to refine the images further.

The plug-and-play solution is distinct in that it combines machine learning-based approaches with traditional engineering physics approaches, iterating between them to deliver the image.

Once fully implemented, the methodology could cut MRI reconstruction time in half. It requires no hardware modification; a computer workstation connected to the MRI scanner will perform the computations. Clinicians want to take a look at the MRI images within seconds. After development, the algorithm will be able to recover the scan images in a matter of seconds, almost in real-time.
