Design Engineer

Designed the Visimax injector which involved hardware modules, prototyping, circuit design and layout, state machine driven firmware, and testing or V&V for Imaxeon injector. The Visimax injector used a backlit graphics monochrome display which flipped when the injector head was lifted for filling. The Visimax has now sold over 500 units, with arguably a very low failure rate, and a very efficient battery and charging system.From 2001 to 2006, I was the chief designer on the Avidia Angio injector which uses a colour touchpad and 5 controllers, and could inject a 150ml syringe in 3s into the heart with 1200psi to an accuracy of better than 0.1ml. The pressure sensing was very accurate with a 6-term formula based on speed, flow and current. Over 300 Angio injectors have been made to date, and the Avidia has CE and TGA approval.The current Salient injector is based on work done on the Avidia.
