LVM issues

Hi.

I have raid-1 (mirror) which contains LVM .

After my system crashed I made dd if=/dev/md1 of=md1.img

since my /dev/md1 is damaged for now, only backup i have is in that file.
is there possible to mount lvm volumes from that file directly, without haveing to write it to physical disk?

and if I want to write it to physical disk is 'dd if=md1.img of=/dev/md1' ok?

thanks..

o and raid itself is running (degraded and with 1 disk only but running).
just filesystem on /dev/md1 is messed up.

when i made dd if=/dev/md1 of=md1.img it completed with an hour (120GB).
now 'dd if=md1.img of=/dev/md1' is still running after 2 hours....
