Abstract

Highlights
• 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.
