Example on handling online detector ("blood pump") data
Following example shows how on-line
detector ("blood pump") data is first calibrated and corrected for
decay, then transformed into plasma curve and finally combined with TAC
measured from manual samples. You can make a batch file similar to the
one below (name it for example blood2plasma.bat).
Program dft2ps is just
for plotting the curves in different phases.
Program blo2kbq
calibrates and corrects the data for decay. With option
-m you can define the result file to have frame times in minutes
instead of seconds.
Program b2plasma needs
the hematocrit
value to transform blood data into plasma data.
Sometimes the online detector is used only in the beginning of the PET
study and then manual sampling is used for the rest of the study.
Program dftcat combines
these two (beginning + end) curves into one. In
this case, make sure you have the same time unit in both files (use
option -m in program blo2kbq
to get times in minutes). Manually sampled
plasma data is usually already calibrated and decay corrected so you
can use it as such.
