Surgical Illuminant Design for Enhancement of Organ Microstructure

In the medical field, visual diagnosis is one of the most important ways for evaluation. Observing tissue structure is effective for improving precision of surgery. We focused on an emphatic illuminant which brought a fine view of micro blood vessel structures. In this paper, we simulated the illuminant and evaluated it by subjective evaluation. In an evaluation experiment, to compare two illuminant conditions, a conventional and the emphatic illuminant, 14 LEDs fixed to the light unit were spectrally adjusted to demonstrate the two illuminants. We set a rat cecum as a target to observe the structure of micro blood vessels. The effectiveness of the emphatic illuminant was confirmed by ratio of detected blood vessel region to the ground truth.
