Set up of water phantom acquisitions (a); measurements of ${\mathit{\text{GSR}}}_{\mathit{\text{ts}}}$ and ${\mathit{\text{DR}}}_{\mathit{\text{GSR}}}$ were performed in slice 0 which is the median slice of the acquired phantom volume. Scanner‐A (b): images with $\text{BW}=1953\text{Hz}/\text{pixel}$ and $\text{ES}=0.9\text{ms}$. Scanner‐B (c): images with $\text{BW}=1906\text{Hz}/\text{pixel}$ and $\text{ES}=0.9\text{ms}$. The ROIs (b, c) used for the measurement of signal intensity within the phantom $({\mathit{\text{SI}}}_i,\mathrm{i}=1,2,3,4)$ (solid line), and the ROIs used for the measurement of signal intensity of Nyquist ghost $({\mathit{\text{NI}}}_i,\mathrm{i}=1,2,3,4)$ (dashed line) and background (BI) (dotted line), are shown. The ROIs employed for the measurement of ${\mathit{\text{NI}}}_i(\mathrm{i}=1,2,3,4)$ are shifted by N/2 voxels (64/2) along the phase encoding direction in respect to the corresponding ROIs employed for the measurement of ${\mathit{\text{SI}}}_i(\mathrm{i}=1,2,3,4)$.
