Decubitus position is the best for all body types. Make sure your aorta velocity is take above the level of the renals. If the renal artery is visualized your accuracy is in the high 80's.

This GE site is great for positions and a good resource. Also look in the flownet archieves. there are several discussions. Keep up the interest, it's a great means for RAS ... no dye..
