The DCE MRI analysis plug-in. Several models are currently implemented: a simple three-step linear function, a descriptive model, the standard and extended Tofts model and the 2CXM. Arterial input functions can be image-based (from the same image as the analyzed ROI or a different one) and file-based (.csv format). The fit configuration allows for definition of model parameter starting values, parameter constraints and the desired conversion of signal to concentration units
