CoilGen

CoilGen generates realizable connected, non-overlapping wire layouts for MR gradient and shim coils from a given surface mesh and target field using stream-function optimization and the boundary element method.

Key Features:

• Automated Layout Generation: Automates creation of connected, non-overlapping wire paths based on a provided surface mesh and target field to produce realizable coil geometries.
• Algorithmic Steps: Implements stream-function optimization, two-dimensional surface projection, potential discretization, topological contour sorting, opening and interconnecting contours, and addition of non-overlapping return paths.
• Quality Control Parameters: Assesses technical parameters such as current strength, inductance, and field accuracy to evaluate the quality of generated layouts.

Scientific Applications:

• Rapid prototyping: Rapid prototyping of MR gradient and shim coil designs for MRI and NMR research.
• Comparative layout evaluation: Generation of multiple layouts via parameter variation to compare discretization error and field fidelity across designs.

Methodology:

Leverages the boundary element method and optimizes a stream function, followed by two-dimensional surface projection, potential discretization, topological contour sorting, opening and interconnecting contours, addition of non-overlapping return paths, and generation of multiple layouts by varying input parameters.
