3. Navigating inner space

For thousands of years, the interior of the body remained a mysterious unknown territory. Then about the time of the Renaissance, dissections, legal and illegal,  provided the first knowledge of the internal organs.

But save for anatomists and medical students, the body remained a terra incognita. That changed a century ago with the discovery of X-rays . X-rays made the body transparent; internal body structures could be seen by all.

But over time, the damaging side effects of X-rays became apparent. These factors brought about the development of new and safer imaging techniques The new imaging systems of ultrasound, CT, MRI and thermography all provide a new cartography of inner space.
