PROBLEM TO BE SOLVED: To provide a phantom for near infrared imaging device calibration capable of maintaining a fluorescent dye for a long period and suppressing induction of scattering light and the like as much as possible, and further, capable of sharing data even among different models.SOLUTION: A phantom 1, for example, includes: a main body 10 composed of a resin in which at least an external surface 11 is light impermeable; a cylindrical opening part 13 extending from a top surface 11a to a bottom surface 11b of the main body 10; a fluorescent dye 12 stored inside the cylindrical opening part 13; and a cap 20 having light permeability close to the light permeability of an animal tissue and covering the cylindrical opening part 13. At least three or more of the cylindrical opening parts 13 are installed on the main body 10. The cap 20 is installed by the number corresponding to the number of installed cylindrical openings 13. Any of parameters among the thickness t of the cap 20 or the concentration or the amount of the fluorescent dye 12 is set so as to vary. |
