Metrolab Webinar with Prof. Guy Aubert Proceedings

3.11.2020 | Metronews, MFC2046, MRI

 Metrolab virtually hosted Prof. Guy Aubert on October 15th to discuss the use of Spherical Harmonics modeling to describe the magnetic field of a magnet to speed-up the shimming process.

We have recorded both morning and afternoon sessions, here are the presentations as well as Q&A sessions sorted by themes.

Recorded presentation

Introduction by Antoine Daridon from Metrolab and Guy Aubert (8 min 30)
An introduction to Spherical Harmonic Expansion by Guy Aubert (12 min)
