Contrast agents enhance optical coherence tomography

rger relative to the size of the cells, and the cells are less mature when they divide. These changes affect the scattering properties of light, which we can easily detect.

Using contrast agents, scientists might be able to study how cells migrate through tissue and metastasize, Boppart said. Enhanced OCT imaging could even provide surgical guidance in real time to help find a tumor and remove all of it, without taking too much of the surrounding tissue.

In addition to developing novel contrast agents, Boppart and his students are also designing miniature probes and a more compact OCT device. Their goal is to assemble a portable unit that could be placed on a cart and wheeled into a hospital for use on patients.
