1. A fluid injector system, comprising:
at least one injector for pressurizing and delivering at least one fluid from a first fluid reservoir and a second fluid reservoir;
a first fluid path section providing fluid communication between a first bulk fluid container and the first fluid reservoir and a second fluid path section providing fluid communication between a second bulk fluid container and the second fluid reservoir, wherein the first fluid reservoir is a first syringe connected to the at least one injector and the second fluid reservoir is a second syringe connected to the at least one injector;
a first sensor arranged along the first fluid path section and a second sensor arranged along the second fluid path section, each of the first sensor and the second sensor comprising an emitter and a detector,
wherein a first emitter associated with the first sensor and a second emitter associated with the second sensor are configured to emit light through the first fluid path section and the second fluid path section, respectively; and
wherein a first detector associated with the first sensor and a second detector associated with the second sensor are configured to receive the light emitted through the first fluid path section and the second fluid path section, respectively, and generate an electrical signal based on at least one property of the received light; and
at least one processor programmed or configured to determine, based on the electrical signal generated by the first detector or the second detector, at least one of:
an identity of the at least one fluid present in at least one of the first fluid path section and the second fluid path section;
a concentration of the at least one fluid in at least one of the first fluid path section and the second fluid path section; and
at least one property of at least one of the first fluid path section and the second fluid path section, and
wherein the at least one processor is programmed or configured to determine, based on the electrical signals generated by the first and second sensors, that the fluid filling the first fluid reservoir was originally intended by an injection protocol to fill the second fluid reservoir; and the fluid filling the second fluid reservoir was originally intended by the injection protocol to fill the first fluid reservoir, and
adjust the injection protocol to ensure that injection parameters are updated to switch the identity of the first fluid reservoir and the second fluid reservoir so that first fluid is associated with the first fluid reservoir and the second fluid is associated with the second fluid reservoir.
