Looking for medical pictures (perhaps "blueprints" ?)

Hello,

I am using a 3D standard software (Maya from Alias) and
I need to have 2 pictures of a same medical object to
do it in 3D.

But there are constraints about these pictures.

1/ one must be a front view of the object
2/ the other a left (or right) view of this same object
3/ those 2 pictures have to be at the same scale.

Do you know some websites with these types of pictures ?

Thank you Anthony
