Hi Malte,
it looks like a task for a macro. I do not know your exact
requirements, but I see two possibilities:
(1) If you need several measurements in one frame: Add all
selections to the ROI Manager (simply type "t"). Then a
macro could loop over all rois, determine the selection type,
do the measurement, read the values from the Results table
and enter the values into an array.
(Note one of the nice features of the ROI Manager: it remembers
which stack slice a selection belongs to).
(2) If you need exactly one measurement per frame:
Write a macro that loops over the frames, calls "waitForUser"
for each slice, then the user selects the first roi and clicks "ok".
The macro does the measurement, enters the result into an array.
The same for the second type of measurement.
The advantage of this method: the macro could tell the user
exactly what to do, set the appropriate slice and selection tool,
etc. (nevertheless, the user can, e.g. jump back one slice to do
a selection again for correction).
In both cases, finally the macro should print all the values
from the array(s) into a window.
For some of the relevant macro functions, see

that's not too difficult, there are plenty of sample macros
and the Plugins>Macros>Record function will help you.
Hope this helps a bit,
Michael
