MRIDIAN vs. Elekta System
Clinically released
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
Under development
Linear accelerator
1.5 Tesla MRI scanner
More magnetic interference, e.g.
electron electron return effect
Geometric distortion
Functional imaging possible
