A new synchrotron-based imaging technique offers high-resolution pictures of the molecular composition of tissues with unprecedented speed and quality, says Carol Hirschmugl, a physicist at the University of Wisconsin-Milwaukee (UWM).

Hirschmugl and UWM scientist Michael Nasse have built a facility called the “Infrared Environmental Imaging (IRENI)” with a light intensity a million times brighter than sunlight to perform the technique at the Synchrotron Radiation Center (SRC) at UW-Madison. The new technique employs multiple beams of synchrotron light to illuminate a state-of-the-art camera, instead of just one beam.

Using 12 beams of synchrotron light in the mid-infrared range, researchers were able to collect thousands of chemical fingerprints simultaneously, producing an image that is 100 times less pixelated than conventional infrared imaging.

The team tested the technique on breast and prostate tissue samples to determine its capabilities for use in diagnostics for cancer and other diseases. The researchers were able to detect features that distinguished the epithelial cells (in which cancers begin) from the stromal cells, which are the type found in deeper tissues, with unprecedented detail.

This opens the door for development of synchrotron-based imaging that can monitor cellular processes, from simple metabolism to stem cell specialization, says Hirschmugl.

Their work appears March 20 online in the journal Nature Methods.
