Based on open-source software and very flexible hardware setup, the Nexus console is designed for the purpose of advanced low-field MRI techniques through the integration of e.g. auxiliary sensors or advanced image reconstruction schemes.

  • 4-transmit channels (easily expendable)
  • 8-receive channels (easily expendable)
  • Compatible with open source software frameworks for pulse sequence programming (Pulseq) and open data standards (ISMRMRD)
  • Software implementation in Python
  • Compatible with and tested on the open-source MRI OSI² ONE

Using a 3D TSE sequence, PD and T2 weighted image contrast in the brain of a healthy volunteer is comparable to a state-of-the-art proprietary console. We could demonstrate the use of the additional receive channels for self-monitoring and calibration and for EMI detectiona and cancellation.
