 note = {Using fifty-nine standard color cards denoted by the Munsell renotation system and agar test models of the esophageal and the gastric walls, Nd-YAG laser absorption was investigated in relation to differences in surface color of the irradlated target. The black card showed the maximum and the white card the minimum absorption with the Nd-YAG laser irradiation. The statistical analysis from the irradiation experiment with other color cards indicated that there were significant correlations between the absorption of Nd-YAG laser and three attributes of color cards: hue, brightness, and saturation. In irradiation with the Nd-YAG laser to the test models of the esophageal wall, it was observed that the energy of the Nd-YAG laser easily penetrated the translucent first layer and was absorbed mainly by the red-colored second layer. In contrast, laser energy was absorbed only in the first layer during irradiation to the gastric wall model. These results may explain the effects of irradiation observed in Nd-YAG laser irradiation to the esophageal wall.},
