Image quality based on standard imaging quality criteria
The image quality will be appreciated visually at least by a radiologist or a researcher.
Signal quality based on standard signal quality criteria

Comparison of the Signal to Noise Ratio obtained by the component of the MRI system under development and the reference situation.
ignal to Noise Ratio will be measured in arbitrary units.
Comparison of the Contrast to Noise Ratio obtained by the component of the MRI system under development and the reference situation.
Contrast to Noise Ratio will be measured in arbitrary units.
Comparison of blurring and artefacts obtained by the component of the MRI system under development and the reference situation.
Absence of blurring and artefacts will be assessed by at least one radiologist according to an ordinal scale (1 to 5 ; 1 is the worst score and 5 is the better score).
