Abstract
Homogeneity is a key f actor in the
development of low-f ield MRI scanners,
especially f or scanners based on a Halbach
conf iguration. To enable shimming a precise
mapping system is needed, that is cost-effective
and easy to build. Here we present a
measurement robot designed to evaluate the
homogeneity of magnetic f ields. By using a
decentralized control an easier replication
compared to existing systems is achieved. The
positioning accuracy is proven with camera-
based motion tracking. The system has been
validated by mapping the magnetic f ield of a
Halbach magnet.
