The project is proceeding in three directions.
- Creating a new MRI reference artifact designed to assess geometric distortion using NIST’s MRI scanner. The artifact will be small enough to fit within the scanner with sufficient clearance to allow for variation in positioning within the scanner.
We plan to use this artifact to generate a data set that will then be used to assess the accuracy of existing DL-based approaches.
- Develop a targeted MRI simulation capability with attention focusing on physics, scan types, and analysis pathways that are relevant to the MRI reference artifact.
We plan to use this capability to reproduce the MRI component of Zhu, et al., and to document our efforts.
- Prototype a DL-based MRI Inversion problem. This will start by reproducing the results from an existing implementation, AUTOMAP.
