Dfttime v.2.2.3
Analyze plasma TAC files fast and easy. dfttime can help you change sample times in regional or blood/plasma TAC files. Samples with negative times are not saved. Time must be given in the same units that are used in the datafile. Time can be given

Dftcat v.1.4.1
Analyze TACs with this tool. dftcat help you catenate the TACs from the second DFT file to the first one, or to a new datafile. Sample times or correction for physical decay is not changed. Here is an example to use this program: dftcat
Dftsums v.0.1.0
Calculate sum-of-squares with this utility. dftsums help you calculate the sum-of-squares (SS) of difference between two TACs. The procedure is: 1. interpolate data2 to sample times in data1 2. calculate the square of difference at each sample time
Algtimes v.0.1.1
Analyze Allogg ABSS on-line blood sampler data with this tool. algtimes can correct the sample times in Allogg ABSS on-line blood sampler data. Use this, if sampling was accidentally started later than the PET scan. If the new sampling start time is
Blotimes v.1.1.0
Correct sample times in Scanditronics data. blotimes can correct or list the sample times in Scanditronics or GEMS on-line blood sampler (blood pump) data.
Fr4sim v.3.9.1
Calculate tissue curve values with this utility. fr4sim can calculate tissue curve values with short sample time intervals. This software sums up those points within specified time frames to simulate a measured PET tissue uptake curve. Input datafile
Tocr v.0.2.0
Convert head-curve data files with this tool. tocr can convert the head-curve data file from ECAT HR+ (*.r) or HRRT (*.hc) to count-rate (.cr) file format, that is suitable for correction of time-delay between blood/plasma and tissue TACs.
Fit_winp v.0.3.1
Fit blood time-activity curve with this program. fit_winp can fit blood time-activity curve (TAC) from PET [O-15]H2O study to a six or four parameter function, when radiowater is given to patient as a short infusion.Command-line arguments: 1) Plasma
Fit2dat v.2.5.2
PET time-activity curves calculator with this program. fit2dat help you calculate the PET time-activity curves (TACs) using parameters of a mathematical function, which have been fitted to the data previously. Fitfile must be in the DFT fit format;
Dft2dat v.1.2.5
Convert PET tracer time-activity curve data with this program. dft2dat help you convert PET tracer time-activity curve data in DFT format (1) to pure numeric data (with no header information or title lines),
Dftslope v.0.5.0
Analyze DFT files with this utility. dftslope help you find the highest slope of TAC(s) in a DFT file. The intercept with x axis can be used as an estimate of tracer appearance time,
