A fluid injection arrangement in the context of patient imaging systems, in which phases of contrast medium injection and flushing medium injection can be freely and selectably ordered as to make available to the operator and patient a vast array of possible protocols that has hitherto been essentially unattainable. The arrangement provides a programmable KVO phase and the ability to program a first phase of injection procedure as a flushing medium phase.

Apparatus and method for programming a KVO phase and a first phase of an injection procedure as a flushing medium phase

Embodiments of an injector, syringe, syringe interface, and piston/plunger assembly for an injector (of contrast medium, for example) are described. Preferably, the syringe is adapted to engage a syringe interface mechanism such that the syringe may be connected to an injector without regard to any particular orientation of the syringe to the injector or to the piston/plunger assembly.

Front-loading medical injector and syringes, syringe interfaces, syringe adapters and syringe plungers for use therewith

A fluid injection arrangement, particularly involving a systematic fluid injection programming capability, in the context of patient imaging systems, in which phases of contrast medium infection and flushing medium injection can be freely and selectably ordered so as to make available to the operator and patient a vast array of possible protocols than has hitherto been essentially unattainable. Also contemplated is the use of a &ldquo;hold&rdquo; phase, involving an indefinite pause between phases of a protocol, in connection with such imaging systems. Further contemplated is the use of a &ldquo;pause&rdquo; phase in which a pause of fixed duration is pre-programmed into the protocols of MRI Injector systems.
