Abstract:
An object hidden behind a cloudy wall is shown to become visible when the wall is made absorbing. The underlying principle is that the absorption in a random medium preferentially reduces the intensity of the multiple scattered light (noise) over the ballistic signal (image). The intensity of the noise can be reduced below the ballistic signal intensity when the medium is made sufficiently absorbing, thus allowing us to see through an otherwise opaque random scattering wall.

German physicist Wilhelm Röntgen (1845–1923) was experimenting with electrical current when he discovered that a mysterious and invisible "ray" would pass through his flesh but leave an outline of his bones on a screen coated with a metal compound. In 1895, Röntgen made the first durable record of the internal parts of a living human: an "X-ray" image (as it came to be called) of his wife’s hand. Scientists worldwide quickly began their own experiments with X-rays, and by 1900, X-ray was widely...

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.
