b2t_h2o 3.1.0 © 1997-2007 by Turku PET Centre

Simulates regional PET radioactivity concentration curves in [O-15]H2O PET studies from decay corrected blood curve using the one-tissue compartment model. By default, blood flow (perfusion) and tissue concentratios are represented per PET volume (including vascular volume). Command line parameters: 1) Blood file (times in sec) 2) Flow (mL/min/100mL) 3) Partition coefficient of water (p) 4) Extraction coefficient (1 - exp(-PS/f); normally 1.0) 5-6) Vascular volume (%) and the arterial fraction of it (%) 7) Tissue file Options: -nosub Only sample times and total tissue TAC will be written in tissue file -add Simulated TACs are added to an existing tissue data file. By default, existing file is overwritten. -fpt Blood flow (perfusion) is assumed to be given per perfusable tissue volume excluding vascular volume. TAC will still be simulated per regional PET volume including vascular volume. -voiname=<text> Enter a name (1-6 chars without spaces) for the simulated TAC -vena=<filename> Save the simulated venous blood TAC -h or --help Print this message and exit -v, --version, or --build Print software build information and exit --silent Program works silently, printing only warnings and error messages --verbose Program prints lots of information about what it is doing. Calculated tissue activities are written in the specified file with these data columns: 0) Time 1) Total tissue activity (2+3+4) 2) [H2O] in tissue 3) Arterial [H2O] in tissue 4) Venous [H2O] in tissue See also: fit_h2o, avgbolus, dfttime, dftadd, dftren, fr4sim, dftunit Keywords: DFT, simulation, perfusion This program comes with ABSOLUTELY NO WARRANTY.
