water_input 3.0.1 © 2005-2016 Turku PET Centre
Blood pump (ABSS) data preprocessing for [O-15]water PET study.
Resulting blood TAC is calibrated and corrected for physical decay
and optionally for time delay, if countrate file is given.
http://www.turkupetcentre.net/petanalysis/model_radiowater.html
If ABSS collection or PET scan was not started at the same time,
you must correct the time difference manually to the blood TAC
made by this script. Use program tactime for the correction.
Verify the result by looking the created *.svg or *.png plot.
Usage: water_input [options] ABSSfile Outputfile
Options:
-CR:countratefile
Filename for countrate data; if not given, then delay correction
is not done; some perfusion calculation software can do
delay correction later.
-DISP:dispersion
Physiological dispersion constant can be set using this option;
By default it is set to 5.0 s.
-FIT:YES or -FIT:NO
Dispersion can be corrected by simultaneously fitting a function to
the blood TAC (yes), or without fitting (no, default).
