The repository contains many Matlab script used to design coils. The available techniques are:
To work, this script required 3 externals scripts:
- SphericalHamornics
- regu package from C Hansen for the Tikhonov implementation
- YALMIP TOOLBOX from Johan Löfberg for the QP implementation
To start, you have to adapt streamBEM/makeCoil6.m to your installation, and then run it. The definition of the wanted coils is done in a separate files. One files per coil.
The easiest approach to approximate coil centroids: simply defining loops of current at given positions, to make solenoids or gradient coils for example.
Here, BEM formulation is used along with stream function to formulate the coil design as an optimization. 3 Basic examples are presented to make coils for Magnetic Particle Imaging scanner according to this publication. The examples are:
- A circular quadrupole,
- A circular drive coil,
- A planar drive coil,
- A y-gradient coil for MRI,
- A drive coil using a low-density mesh.
This has been extended to evaluate the effect of induced current in surfaces close to the coil on the coil efficiency and field topology. An example for a
- shielded y-drive coil for a MPI scanner
is provided.
Please refer yourself to this publication and my thesis for more details.
Using a multipole expansion techniques, the shape of iron core magnet can be designed. This has been used in this conference contribution to design a human sized MPI FFL scanner. Please refer yourself to my thesis for more details.
