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.
