Keywords: Low-Field MRI, Low-Field MRI, Permanent Magnets
Motivation: The building process of low-field scanners magnets, when composed of a large number of small permanent magnets, is time-consuming and error-prone due to the highly repetitive task.
Goal(s): To design a low-cost and open-source solution making the magnet building process faster and more reliable.
Approach: To use a Hall sensor to distinguish between working and defective permanent magnets. Furthermore, to take advantage of the attractive force between two permanent magnets to identify the polarization direction.
Results: A magnetic test station is designed. CAD drawings and scripts are made available on the GitHub repository.
Impact: A magnet test station allowing for an easy and straightforward testing of small permanent magnets is proposed. The test station makes the construction process of low-field scanner magnets, composed of a large number of permanent magnets, faster and more reliable.
