A new clinical device undergoing testing in the Netherlands uses photoacoustics, or light-induced sound, instead of radiation via X-rays to both detect and visualize breast tumors. Scientists at the University of Twente and Medisch Spectrum Twente Hospital in Oldenzaal are in the first phase of clinical testing for the device. So far, they've used it on 12 patients and determined it can identify cancerous tumors through high-contrast images. What's more, they found that the device offers a higher contrast of cancerous tissue than a regular X-ray mammography does. Details are published in the open-access journal Optical Express. Release
