heartcor - tpcclib 0.7.0 © 2018 by Turku PET Centre

Corrects regional myocardium and blood time-activity curves (TACs)
measured with PET for recovery and spillover fractions, and contribution
of blood activity in vascular space (10%) (Henze et al., 1983).
This method works properly, if regions-of-interest (ROIs) are drawn
in the middle of cavity and muscle, excluding the border areas.
Method is valid when cavity radius >> wall thickness and FWHM/2.36.
Usage: heartcor tacfile cav_id myo_id diameter thickness FWHM outputfile
Tacfile must contain at least the TACs of myocardial cavity and entire
myocardial muscle (or representative region of it). The names or numbers
of these TACs must be given as next command-line parameters.
Corrections based on these TACs are applied to any additional TACs in tacfile.
The diameter of cavity, myocardial wall thickness, and PET image resolution
must be given in millimeters.
 -Vb=<Vascular volume fraction>
     Set vascular volume fraction (0-0.9) in myocardial tissue;
     by default Vb=0.10
     Recovery and spillover errors are simulated and added to initially
     non-affected data, originating from compartmental model simulations;
     enter blood and muscle tissue TACs instead of cavity and myocardial
     region TACs, respectively.
