A diagnostic scan may be planned in as little time as possible based on localization using multiple scout scans of different regions of the patient. The planning of the different regions may be optimized to minimize the number and/or time for localizing the target.

Abstract: For artificial Intelligence-based optimization of a MR sequence, an agent machine trained with reinforcement learning generates the MR pulse sequence for a patient. The agent may generate values for multiple or all the parameters defining the MR pulse sequence. The agent was trained using the end goal or task (e.g., MR map or segmentation) as the reward function, so the MR pulse sequence generated by the agent provides good quality MR imaging. The agent generates the MR pulse sequence quickly and without requiring multiple sequences to be used on the patient.

Abstract: For reconstruction in medical imaging, self-consistency using data augmentation is improved by including data consistency. Artificial intelligence is trained based on self-consistency and data consistency, allowing training without supervision. Fully sampled data and/or ground truth is not needed but may be used. The machine-trained model is less likely to reconstruct images with motion artifacts, and/or the training data may be more easily gathered by not requiring full sampling.
