Claim 18:
19. A system for processing magnetic resonant imaging (MRI) data, the system comprising:
an MRI workstation;
a plurality of MRI scanners;
a display;
at least one controller operatively coupled to the MM workstation, the plurality of MRI scanners, and the display; and
a memory coupled to the at least one controller, the memory storing instructions that, when executed by the controller, performs a set of operations comprising:
receiving, at the MRI workstation, respective electronic MRI data of an imaged tissue volume acquired by different ones of the plurality of MRI scanners over respective periods of time after a respective contrast agent is introduced into a patient while at least a portion of the patient is positioned within respective different MRI scanners;
converting, by the at least one controller, a plurality of signal enhancement ratio curves associated with the respective electronic MRI data from the different MRI scanners into an absorption rate curve, the absorption rate curve describing absorption rates of the respective contrast agent in the imaged tissue volume and compensating for a non-linear relationship between an MRI signal generated by an MRI scanner during imaging of the imaged tissue volume and a concentration of the respective contrast agent over time;
wherein the absorption rate curve is determined by deriving, via the at least one controller, a signal intensity ratio for the imaged tissue volume based on an actual absorption rate of the respective contrast agent in the imaged tissue volume for all of the different MM scanners;
normalizing, via the at least one controller, the derived signal intensity ratio for the imaged tissue volume so that a signal enhancement ratio is independent of the MRI scanners used to generate the electronic MRI data; and
displaying, at the display, the absorption rate curve of the respective contrast agent in the imaged tissue volume.
