ROI-based analysis

import dcmri as dc

time, aif, roi, _ = dc.fake_tissue(CNR=50)   # Generate some test data
tissue = dc.Tissue(aif=aif, t=time)          # Launch a tissue model
tissue.train(time, roi)                      # Train the tissue on the data
tissue.plot(time, roi)                       # Check the fit to the data

tissue.print(round_to=3)                     # Print the fitted parameters

Pixel-based analysis

n = 128
time, signal, aif, _ = dc.fake_brain(n)      # Generate some test data
image = dc.TissueArray((n, n),               # Launch an array model
   aif = aif,
   t = time,
   kinetics = '2CU',
   verbose = 1)
image.train(time, roi)                       # Train the tissue on the data
image.plot(time, roi)                        # Plot the parameter maps
