Perfusion is the name given to the delivery of blood and its constituents to tissue. A contrast injection can be given which makes this process visible in MR images. A gamma function can be fitted to the concentration time curves in order to extract parameters associated with perfusion.
Configure TINA with the command `tinatool -f perf' or running tinatool2.sh. Generate a binary region of interest in the imcalc tv. and compute selected fit parameters ''gamma fit''. Primary parameters are relative blood volume (CBV) and bolus arrival time (TTM). The results can be displayed as a parametric image in the imcalc tv. Having run the initial analysis, images for each of the fit parameters can be generated via the choice dialog switches.
