imgdelay - tpcclib 0.8.0 © 2023 by Turku PET Centre

Make a map of time delay between dynamic PET image and BTAC.
Reversible one-tissue compartment model with blood volume is applied.
Positive delay time means that tissue curve is delayed as compared to
the input curve, and vice versa. Thus, input curve needs to be moved
by the delay time to match the tissue curve.
Currently only NIfTI format is supported.
Usage: imgdelay [options] imgfile btacfile delaymap
 -min=<Time (sec)> and -max=<Time (sec)>
     The range of time delays to be tested; by default -10 - +50 s.
     Large range will increase computation time.
 -end=<Fit end time (sec)>
     Use data from 0 to end time; by default, 300 s. End time may need to
     be reduced so that BTAC with negative delay extends to end time.
     Pixels with AUC less than (threshold/100 x BTAC AUC) are set to zero.
     Default is 1%.
     Vb map is saved in units mL blood/mL PET volume.
     K1 map is saved in units mL blood/(min*mL PET volume).
