Yes, though of course it won't be possible to boot from the CD.
Just do:  (assuming the cd is already mounted under /cdrom, and the
file is "main.raw")
mount -t iso9660 -o loop,ro /cdrom/main.raw /mnt

Then, assuming this works, the best thing to do is probably to create
a specific directory to mount it on (say /mnt/debiancd - of course,
you need to umount the cd image first) and then place a line like this
is your /etc/fstab:
/cdrom/main.raw  /mnt/debiancd  iso9660  loop,ro,noauto 0 0

Now you can mount it with just "mount /mnt/debiancd".

Then, use dselect's "mountable" access method - I suggest this because
it's faster than the "mounted" method and accessing things through the 
loop device is going to slow things down a bit to begin with.
