Randomized trial demonstrates advanced imaging of gastrointestinal lesions, indicating enhanced diagnosis and treatment options.
and image large‑scale irregular regions and minute areas down to 100 µm. In ex vivo experiments on porcine gastric tissue, the penetration depth achieved 4 mm, with SNRs exceeding 13 dB and contrast values all greater than 0.5. In vivo experiments enabled targeted imaging of lesions in nude mice. Furthermore, a wireless-powered, magnetically controlled device ensures continuous energy and precise motion for NIR‑II FICE. To our knowledge, this is the first CE platform for NIR-II fluorescence imaging, advancing non-invasive gastrointestinal disease diagnosis/treatment and clinical research.
