Noninvasive real-time characterization of non-melanoma skin cancers with handheld optoacoustic probes

Photoacoustics, 2017
Currently, imaging technologies that enable dermsurgeons to visualize non-melanoma skin cancers (NMSC) in vivo preoperatively are lacking, resulting in excessive or incomplete removal.
