Two views (Photo 1 and 2) of the chest before corset training started.

The position of the heart is reversed due to the copying process. This does show the rib cage and spine.
Notice the narrow appearing disc and the straight spine.

The other views (photo 3 and 4) show Cathie after years of corseting with the corset on. Notice the wider disc due to the stretching of the body with the corset. This protects the disc. Notice the obvious narrowing of the rib cage with the corset on.
The last two ribs on each side are the "floating ribs". Notice most of the chest and heart are not compressed by the corset. The rib cage is reshaped. Notice the back remains straight and protected. These last X-rays are after 15 years of corseting.
Cathie without her corset. X-ray taken in Japan. Prominent change of the ribcage.
