MOIN spin library - overview

Magnetic resonance Open source INitiative (MOIN) spin library was written in University Medical Center Schleswig-Holstein (UKSH), Kiel University, Department of Radiology and Neuroradiology, Section for Biomedical Imaging, Molecular Imaging North Competence Center (MOIN CC) by Andrey N. Pravdivtsev and Jan-Bernd Hövener in 2018.
MOIN spin library was developed for computation of various aspects of magnetic resonance (MR):

  1. Spin: evolution of single spin in homogeneous or inhomogeneous magnetic fields;
  2. MR-imaging: evolution and acquisition of MR-signal from digital phantom with variably defined characteristics (proton (or other nuclei) density, initial polarization value, T1, T2-relaxation times) in inhomogeneous magnetic field.
  3. Density matrix: evolution of density matrix under arbitrarily conditions for simulation of multi spin system at liquid state, i.e. simulation of NMR-spectra, spontaneous or induced by RF-fields polarization transfer, chemical exchange.

The main goal of the library was to develop an easy tool for improving hyperpolarization experiments, acquisition and reconstruction of MR-imaging and chemical exchange analysis.
The library has an open source and goes with various examples and manual. The user can use/modify/check already written functions/objects or develop his own.
Currently the library is developing an in case of any questions, suggestions or contribution to the library please contact:

When the library is used in publications please provide us with a source code and on this page we will share it with MR-community and other library users.
Disclaimer: some parts of the library are in developing stage and not have been tested properly and may contain mistakes. We are working on that. If user will find some issues, please let us know and we will fix that issue.
