Combining Light and Sound For Accurate, Painless 3-D Mammograms

Breast cancer screening today requires exposure to X-ray radiation. The X-ray images are difficult to interpret, causing anxiety-inducing false alarms and extensive follow-up tests that include biopsies. Besides, getting a mammogram is quite literally a pain, requiring an uncomfortable compression of the breast tissue.

Startup OptoSonics in Oriental, N.C. aims to make breast imaging more accurate, quick, painless, and radiation-free. The company’s technology relies on the photoacoustic effect—the generation of sound from light absorption—to create high-resolution 3-D images of the network of blood vessels inside the breast. “The idea is that because tumors induce the creation of additional blood vessels, you’d see a brighter spot and individual vessels feeding into the mass,” says Robert Kruger, the company’s president and co-founder. Kruger and his colleagues presented details of the technique at the Acoustical Society of America meeting last week.
