A Tabletop MRI system was developed that merges the Marinos Center Tabletop and OCRA projects, and is improved in many aspects compared to the original system. The proposed system includes a fully functional MRI console with a customizable GUI and microcontroller server. The hardware was extended with an optimized magnet design with passive shimming, active TR switches with reverse bias and RFPA noise blanking, and a low cost and fast response 4 channel gradient amplifier. It can be used for educational purposes and student courses in medical engineering.
