National Instruments article on imaginSYS Multi-Channel Spectrometer
Independent 8 channel MR Spectrometer with advanced software and sequence capability (see MR Software and Sequence products for specifications) for clinical and research applications and also for OEM MR System integrators. Additional modules can be added to create 16, 24 or 32 channel systems. A range of Gradient and Radiofrequency Amplifiers can be sourced and integrated into the RF shielded single cabinet spectrometer enclosure.
