We have developed a compact inexpensive system for observing lymphatic vessels through the skin tissue. This method utilizes the high transmittance of near-infrared light through skin tissue and water; it is free from the dangers of radiation. Indocyanine green is used as the contrast dye, and it absorbs and emits near-infrared radiation. A few hours after injecting the dye solution subcutaneously, the lymphatic vessels are clearly observed using an infrared camera.
