iFit
A software package for region-based tracer kinetic modeling
Developed by Ole Lajord Munk

A program for kinetic analyses of dynamic PET data: time-activity curves are loaded into iFit where kinetic models can be fitted to your data. iFit contains most tracer kinetic models (mainly compartment models), input models (to correct for time-delay and dispersion), models for metabolite correction, an interactive tool for choosing an initial guess, a powerful custom-made optimizer, and more.

You may download and use iFit for free.

You are encouraged to report bugs and suggest improvements to olelajmu@rm.dk but I cannot promise to correct or update the software (iFit is a project that I work on during my spare time). Thus, I will read your e-mail but cannot promise a personal answer to all e-mails.


Download

Thank you for downloading iFit

iFit has been used for years at the PET Center in Aarhus and at various sites around the world - and has been used for kinetic analysis in more than 50 peer-reviewed papers. Thus, iFit has been thoroughly tested by many people. Still, only download iFit if you accept this:

Test data and quick guide (optional)
The ZIP file contains a very basic set of data to play around with. Also, you may use the files to check some of the simple data formats that can be loaded into iFit
