Noninvasive Imaging Method Can Penetrate Deeper Into Living Tissue

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 deeply 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. Read on to learn more.
