I use a program by kinetic imaging
http://www.kineticimaging.com/
It was originally written by Dan Zicha and Graham Dunn at King's college London to track cells.
It will either do it automatically, by thresholding, or you can use the mouse to track cells manually.
The data is exportable to a spreadsheet such as excel, or mathematica notebook for analysis, although the program also does some analysis as well.
I'd recommend it.

Dear Gabor,
I am not aware of such software.
My suggestion is that you don't use Phase-Contrast (or DIC for that matter).
If you want a single image that will show you RI
changes, use dark field. I know that doing this
as NA >1 is difficult but I think that you will
find that an NA 1.0 lens will give you a better
and more easily interpretable image in dark field
than a 1.2 NA phase of DIC setup on most living
specimens.
(doesn't work well on thick specimens with a lot
of "out-of-focus" scattered light.)
