Abstract

A power injector (302) with syringe communication logic (316) is disclosed. A communication with a syringe (320) for the power injector (302) may be initiated via data provided by one or more of a tilt sensor (306), a syringe clamp sensor (308), a prefilled syringe sensor (310), or an imaging energy output sensor (312).

Claims
