WG 2: Software and Tooling

WG 2 Leader: Dr. Emine Saritas

WG 2 Co-leader: Dr. Damla Alptekin Soydan

Working Group 2 (WG 2) focuses on software development for Magnetic Particle Imaging (MPI), covering particle physics simulations, scanner instrumentation (e.g., magnetic fields, signal induction, coil coupling), image reconstruction, and image processing. Our goal is to define software interfaces that enable seamless integration of different research tools. WG 2 also bridges the gap between software developers and application researchers, ensuring that MPI software is both functional and optimized for real-world use.

WG 2 structure & How to join

This working group is leaded by Dr. Emine Saritas and Dr. Damla Alptekin Soydan and includes > 36 researchers from 19 countries. Click here to see the participant list & How to Join.

Tasks:

  • Identify currently available MPI software packages and categorise them according to their functionality, development status, performance and the programming language used
  • Use the gathered data for identifying a lack of functionality in the MPI software landscape and include additional end-user feedback
  • Develop programming-language agnostic file formats for simulation environments (e.g. coil setup, MNP parameters, sequence parameters), raw MPI data (e.g. voltage signals, measurement parameters), and data reconstructions

  • Develop unit tests that are performed with continuous integration (CI) services and test the inter-operability of different software packages
