摘要：
A magnetic resonance imaging scan performs an MRI acquisition using an undersampling pattern to produce undersampled k-space data； adds the undersampled k-space data to aggregate undersampled k-space data for the scan； reconstructs an image from the aggregate undersampled k-space data； updates the undersampling pattern from the reconstructed image and aggregate undersampled k-space data using a deep reinforcement learning technique defined by an environment, reward, and agent, where the environment comprises an MRI reconstruction technique, where the reward comprises an image quality metric, and where the agent comprises a deep convolutional neural network and fully connected layers； and repeats these steps to produce a final reconstructed MRI image for the scan.
