| Abstract(in English) | We have been developing a device for imaging muscle oxygenation using spatially resolved spectroscopy. To validate the measurement reliability of the device, we previously used tissue-mimicking liquid phantoms using red blood cells. However, validation could not be sufficiently performed due to unstable optical properties and poor reproducibility of the liquid phantoms. Therefore, we constructed plastic phantoms that mimic the optical properties of backscattered light from muscles with the aim of establishing a more stable and simple method for validation. Clear plastic was used as the base resin, and the concentrations of absorber and scatterer were adjusted accordingly to mimic the absorption and scattering of light in muscle and adipose tissues. Values of absorption coefficient μ'_s and reduced scatter coefficient μ'_s of the muscle tissue phantoms (μ_a=0.019-0.047 mm^<-1>, μ'_s=0.53-0.68 mm^<-1>) and adipose tissue phantoms (μ_a=0.0002-0.0052 mm^<-1>, μ'_s=0.83-1.05 mm^<-1>) were measured using time-resolved spectroscopy, and the values showed good agreement with those of actual tissues. |
