Abstract
A system for enabling delivery of fluid in an injection procedure to be performed on a patient in connection with a diagnostic imaging procedure is disclosed. The system includes a controller operably associated with at least one pressurizing mechanism though which at least one of a first and a second fluid contained within at least one fluid container is injectable into the patient. The first fluid includes a contrast enhancing agent while the second fluid does not. The controller includes a programming system for programming an injection protocol having a plurality of phases to effect enhancement of at least one region of interest of the patient over a scan duration of the diagnostic imaging procedure. The programming system includes an algorithm that enables computation of a ratio of the first and second fluids based on at least a peak enhancement that occurs in at least one region of interest.
