Fig. 5.

Rows 1–3 show three consecutively acquired images for scans performed with no gating (column A), with CR-gating but no automatic respiratory reacquisition (column B), and for CR-gating with automatic respiratory reacquisition (column C). Row 4 shows the ‘best representation’ image which was produced from the average of the 20 image volumes acquired using cardio-respiratory synchronisation with automatic reacquisition of respiratory motion corrupted data. Arrow tips are used to highlight some example structural features. Column C shows a consistent and faithful detection of the example structural features in rows 1–3 demonstrating improved image stabilisation.
