The BioOptics World take on this story:

Washington University St. Louis (WUSTL; Missouri) researchers have developed a photoacoustic imaging technique that can quantify the elasticity of human tissue, so it could be used to monitor the elasticity of the cervix during pregnancy to, for example, predict preterm deliveries.

The technique, which they call quantitative photoacoustic elastography (QPAE), combines photoacoustic elastography (which measures strain) with a separate stress sensor. The combo approach yields an image that shows both the stress and strain distribution, allowing calculation of an absolute elastogram.
