Abstract: The present work aims at developing static phantom for rat brain to model the inhomogeneities in the brain tissues. The inhomogeneities have been modelled by varying the concentration of the fluids that mimic those inhomogeneities. The local variations in various parts of brain can be considered as different concentration of substances and accordingly having different optical attributes. Near-infrared spectroscopy (NIRS) has been used to detect and estimate these local changes that indicate different brain activities. The paper presents the development of static rat brain tissue phantoms and its analysis using a single channel near-infrared spectroscopy (NIRS) system. Homogeneous phantoms have been prepared with different concentrations of agarose and intralipid. For different concentrations, the NIRS signal has been acquired at dual wavelengths (770 nm and 850 nm). With increase in the concentration of intralipid, an increase in the amplitude of NIRS signal was noted. The response o btained due to 770 nm and 850 nm sources corresponded to lower and upper amplitude respectively. (More)
