Her physicians suspected she had a brain lesion, and with Hounsfield's equipment they were able to see clearly a dark, circular cyst in her brain.

It was especially useful for looking at head injuries and brain problems, because it showed about 100 times greater detail in soft tissues than traditional x-rays.
