1. A method for injecting a fluid medicament from a syringe into a patient, the method comprising:
providing a syringe and a cassette, wherein the cassette has a latch mechanism for holding the syringe in position relative to the cassette and the syringe includes a syringe chamber for holding the fluid medicament therein and an injection needle fluidly coupled with the syringe chamber;
selectively coupling the cassette with an injector, wherein the injector has a first motor at least selectively operably engageable with the latch mechanism for selectively latching and unlatching the syringe from the cassette, and at least selectively operably engageable with the syringe for moving the syringe in an unlatched state between a first position wherein the injection needle is withdrawn and concealed within the cassette and a second position wherein the injection needle extends from the cassette, and a second motor at least selectively operably engageable with the syringe for expelling the fluid medicament from the syringe when the syringe is in the second position, and a computer configured to control the first and second motors; and
activating the injector to perform a duty cycle for an injection of the fluid medicament from the syringe.
