Real results from real customers advancing the field of medical imaging
At a beta test site, VERIFLUX identified critical performance issues with a new 32-channel head coil that standard fMRI tests completely missed, preventing potential misdiagnoses.
NeuRA Imaging became the first facility globally to implement GSP's SPIRIT phantom, supporting Australia's National Imaging Facility MRNet project to harmonise imaging protocols across multiple sites.
A 22-scanner study across 19 sites demonstrated that SPECTRE phantoms enable cross-calibration of MRS measurements, reducing variability and improving sensitivity for multi-site clinical trials in metachromatic leukodystrophy.
