Abstract
This invention provides a phantom whose light propagation characteristics and acoustic propagation characteristics are similar to those of human tissues and which allows detection of an absorber also with an ultrasonic wave diagnostic apparatus and allows adjustment of the oxygen saturation. A phantom has light absorberstoin a phantom base material, in which the light absorberstoapproximate the light absorption coefficient ratio at two or more wavelengths to that of biological tissues, and the acoustic propagation characteristics of the phantom base materialand the light absorberstoare different from each other.
