Patent ID: 7937134

Claim:
An injector system for use with an imaging system in producing a contrast-enhanced image of an internal region of a patient, the injector system comprising: (a) first and second pressurizing units for pressurizing a contrast medium and a diluent, respectively, for injection into the patient during an injection procedure; (b) an injector control unit including programming therefor, the injector control unit operating according to the programming and injection parameters programmed therein for controlling the pressurizing units so as to enable a desired ratio of the contrast medium to the diluent to be injected into the patient during the injection procedure; and (c) an injector interface in communication with the injector control unit, the injector interface being connectable to the imaging system through an imager interface thereof so as to enable the injector and imaging systems to exchange digital information therebetween for the purpose of enabling at least one of (i) closed loop control of one of the systems by the other of the systems based upon at least one of (A) selected portions of the digital information from at least one of the imaging system and the injector system and (B) a physiological condition of the patient obtained from a sensor thereof and (ii) adjustment of the desired ratio in accordance with the programming and at least some of the digital information received from the imaging system so as to achieve a desired level of enhancement therewith within the internal region of the patient of which the images are acquired by the imaging system during an imaging procedure.
