Those are available from the Index.dat file.  See documentation here:

https://openslide.org/formats/mirax/
https://lists.andrew.cmu.edu/pipermail/openslide-users/2012-July/000373.html

and ImHex pattern here:

As far as I know, the mapping from associated image to DAT file also
can only be determined by reading the Index.dat, and cannot be derived
solely from the Slidedat.ini or from the DAT files directly.
