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