Dual-Channel High-Speed Photoacoustic Microscopy Revolutionizes Wide Imaging

Researchers unveiled a dual‑channel high‑speed photoacoustic microscopy system that captures wide‑field images up to 10 mm in a single shot, effectively doubling acquisition speed compared with single‑channel setups. The platform synchronizes two laser beams and parallel acoustic detectors, delivering sub‑micron resolution while maintaining low laser fluence for safer tissue exposure. Early tests on vascular phantoms and ex‑vivo mouse organs demonstrated real‑time functional imaging of blood‑oxygen dynamics. The technology promises seamless integration with existing ultrasound platforms, opening new pathways for clinical and pre‑clinical research.
