Abstract

A system, method, and computer program product are disclosed for a flow algorithm that utilizes changes in fluid pressure over a set time interval to calculate a true flow rate compared to a programmed flow rate, identifies any over- or under-delivery of the amount of fluid delivered over the set time interval, compensates for any identified over- or under-delivery of fluid flow rate over a subsequent set time interval, and repeats the flow algorithm for a series of subsequent set time intervals over the duration of the fluid injection procedure.
