    • Air bubble artefact is a new type of CT artefact on CT heads.
    It is produced by gas bubbles in the tube oil cooling system.
    • It can cause inconsistent, illdefined areas of low attenuation mimicking pathologies.
    • The usual physics checks and QC may be inadequate to confirm these.
    • Equipment manufacturers may lack automatic alarms to detect these.
