Abstract: A calibration system for calibrating a pressure output of a fluid injector having a housing configured for connecting to the fluid injector; a drive member engagement portion configured for contacting a drive member of the fluid injector; a compressible member, which may have a known modulus of compression, connected at its proximal end to the drive member engagement portion, wherein the compressible member is compressed with movement of the drive member of the fluid injector between a first, uncompressed position and a second, at least partially compressed position of the fluid injector in a distal direction; and a sensor connected to the compressible member is described. The sensor is configured for measuring at least one of a force imparted by the drive member and a displacement of the drive member when the compressible member is in the second, at least partially compressed position. The system may generate a calibration curve for the drive member of the fluid injector and allow the generation of a fault condition. Methods for calibrating a fluid injector are also described.

Abstract: A method of delivering a multi-phase fluid injection to a patient via a fluid injector comprising two or more syringes includes injecting a first fluid of the fluid injection from at least a first syringe at a first predetermined flow rate, wherein the first fluid has a first viscosity; injecting an initial portion of a second fluid from at least a second syringe at an intermediate flow rate different than a second predetermined flow rate for a specified time, the second fluid having a second viscosity different from the first viscosity; and injecting a remaining portion of the second fluid of the fluid injection at a flow rate at the second predetermined flow rate. A fluid injector system configured for delivering a multi-phase fluid injection is disclosed.
