In 1895, Wilhelm Ro¨ntgen presented a paper to the Wu¨rzburg Physical and Medical Society in Germany on x-rays entitled, “On a New Kind of Ray.” The amazing ability of these rays to pass through solid objects was immediately recognized as more than a curiosity: X-rays can be used to create images of solid objects, in which the image is a spatial map of the object’s susceptibil- ity to penetration by the rays (Figure 12.5). The first Nobel Prize in Physics in 1901 was awarded to Ro¨ntgen for this work. The prize was given in physics because of the importance of these rays as a fundamental new phenomenon, but x-rays would prove to be of enduring practical significance in medical imaging.
