pyCoilGen is an open source tool for generating coil winding layouts, such as gradient field coils, within the MRI and NMR environments.
pyCoilGen is based on a boundary element method and generates interconnected non-overlapping wire-tracks on 3D support structures.
The source code for pyCoilGen is available on GitHub.

With pyCoilGen, you can:
- Specify a target field (e.g.,
bz(x,y,z)=y) and a surface mesh geometry. - Use built-in surface mesh geometries or 3D meshes defined in
.stlfiles. - Generate a coil layout in the form of a non-overlapping, interconnected wire track to achieve the desired field, exported as an
.stlfile.
For a detailed description of the algorithm, refer to the research paper CoilGen: Open-source MR coil layout generator.
The examples directory in the GitHub repository contains several usage examples for pyCoilGen. These examples demonstrate different scenarios and configurations for generating coil layouts.
