Download the mmls tool from TSK (The Sleuth Kit) and run it against your disk image. It will output the starting and ending sectors of each partition and its length. You can then use dd to carve out each partition from the disk image using a block size of 512, the skip option to skip forward to the start of particular partition and count option to specify the number of blocks to copy (length).

mmcat [-t mmtype ] [-o offset ] [ -i imgtype ] [-b dev_sector_size] [-vV] image [images] part_num DESCRIPTION

-t mmtype Specify the media management type. Use '-t list' to list the supported types. If not given, autodetection methods are used. -o offset Specify the offset into the image where the volume containing the partition system starts. The relative offset of the partition system will be added to this value. -b dev_sector_size The size, in bytes, of the underlying device sectors. If not given, the value in the image format is used (if it exists) or 512-bytes is assumed. -i imgtype Identify the type of image file, such as raw or split. If not given, autodetection methods are used. -v Verbose output of debugging statements to stderr -V Display version image [images] One (or more if split) disk images whose format is given with '-i'. part_num Address of partition to process.
