Development of artificial hemoglobin phantom using inks and capillary glass tubes
Abstract
We demonstrate a nonbiological model that mimics the optical behavior of hemoglobin in blood circulation. This physical model enables the testing of imaging devices for measuring oxygen saturation (SpO2) without the need for ethical clearance. The model consists of capillary glass tubes filled with inks that replicate the wavelength-dependent properties of hemoglobin. To verify its feasibility, the model was tested by imaging it under red and infrared illumination.
