"Commercially available high-resolution three-dimensional optical imaging modalities-including confocal microscopy, two-photon microscopy, and optical coherence tomography-have fundamentally impacted biomedicine. Unfortunately, such tools cannot penetrate biological tissue deeper than the optical transport mean free path (similar to 1 mm in the skin)," scientists in the United States report. "Photoacoustic tomography, which combines strong optical contrast and high ultrasonic resolution in a single modality, has broken through this fundamental depth limitation and achieved superdepth high-resolution optical imaging. In parallel, radio frequency-or microwave-induced...
