MRIDIAN vs. Elekta System





Clinically released

Under development





Using three Cobalt sources  Linac under development 0.35 Tesla MR scanner  Less magnetic interference, e.g. electron return effect  Hardly any geometric distortion  Less suited for functional imaging

Linear accelerator





1.5 Tesla MRI scanner 

More magnetic interference, e.g. electron electron return effect  Geometric distortion  Functional imaging possible
