Installed the Whole Body Linac-MR v.1 into an existing vault (20 x 20 x 12 ft high)
without removing and rebuilding the walls or ceiling. The MR magnet features a high
temperature superconducting magnet that does not require liquid helium or a helium exhaust vent.
A Whole Body Linac-MR v.2 with a 60 cm (H) x 110 cm (W) patient gap is being constructed.
2014
July - Acquired the first good MR images of a human subject with the Whole Body Linac-MR v.1.
Clinical Linac-MR System v.1 (0.6T MR, 6MV, 60cm gap).
2021
August - Clinical Trials with Linac-MR (LMR) P3 system
begin. Northern LIGHTs-1, is the 1st of several clinical trials. This trial
will only have imaging.
2023
February - Clinical Trial, Northern LIGHTs-2 begins, with first-in-human treatments
