Synopsis

Keywords: Gradients, Gradients, Open Source

Motivation: Design fully documented gradient systems for the OSI2 open source MRI scanner that can be adapted and replicated.

Goal(s): Make all design and post-processing steps open source to enable for replication and adaptation. Generate a conventional and an alternative design which is rotated by a magic angle such, that all channels exhibit similar efficiency and inductance.

Approach: Gradients were designed using CoilGen, 3D Objects were modified using Blender. Final STL files are available for replication.

Results: All files and steps of a conventional and a rotated magic angle coil are openly available on Gitlab.

Impact: We enable others to replicate and easily adapt MRI gradient coil designs. This includes all post-processing steps which allows to altered the designs to specific requirements.
