Abstract
An air bubble detection system includes an air bubble detector which is disposed downstream from a syringe or manifold used during an angiography procedure. The air bubble detection system monitors contrast medium being injected into the patient and creates an alarm or other indication if the air bubble exceeds any desired threshold.
