Looking
Into the Brain with Lasers
Professor
Enrico Gratton, Department of Physics, UIUC
Parts of our body are
relatively transparent to light. When red light is used for
illumination, the
light will pass through several centimeters of tissue. The reason why
we cannot
see through our body is because of multiple scattering due to cells and
organelles. By reconstructing the path the light followed when passing
through
the tissue, it is possible to determine the shape of internal organs
and their
optical properties. In this talk, the physical principles that are used
to
reconstruct the interior of the body are explained as well as a number
of
applications to medicine and psychology.
