German physicist Wilhelm Rontgen is recognised as the first individual to study the properties of X-rays in 1895. Roughly a decade later, X-rays would be adopted as a medical tool to non-invasively observe patients. The ability to study a subject without the need for vivisection provided an important new alternate methodology to many animal studies. The discovery and development of X-ray imaging would uncover a new category in alternatives that now included technologies such and MRI, CT and PET scans.
