FIELD: physics.
SUBSTANCE: invention can be used to detect data when used in combination with a device for magnetic resonance imaging (MRI). Essence of invention consists in that magnetic field detection unit serves for detecting a temporally varying magnetic field generated by MRI apparatus, and a time-stamping unit generates magnetic field detection timestamps in dependence of detected temporally varying magnetic field.
EFFECT: enabling determination of time ratio with collected MRI data.
