Noninvasive imaging method can penetrate deeper into living tissue

Using high-powered lasers, this new method could help biologists study
the body's immune responses and develop new medicines.

Metabolic imaging is a noninvasive method that enables clinicians and
scientists to study living cells using laser light, which can help
them assess disease progression and treatment responses.

But light scatters when it shines into biological tissue, limiting how
deep it can penetrate and hampering the resolution of captured images.

Now, MIT researchers have developed a new technique that more than
doubles the usual depth limit of metabolic imaging. Their method also
boosts imaging speeds, yielding richer and more detailed images.

Greater penetration depth, faster speeds, and higher resolution make
this method particularly well-suited for demanding imaging
applications like cancer research, tissue engineering, drug discovery,
and the study of immune responses.
