Abstract

Multispectral endoscopic imaging is a promising technique for lesion detection, and surgical guidance. Based on different spectral properties of tissues, multispectral imaging can provide enhanced contrast of vascular structures (narrow band imaging) or enable the quantitative analysis of hemoglobin and lipid. The multiparameter phantoms serve as efficient tools for system calibration, performance evaluation, and algorithm development in multispectral endoscopy are needed. In this paper, we developed a multiparameter tissue-mimicking phantom that mimics the parameters of human gastric mucosa, such as scattering coefficient, scattering layer thickness, vascular width, lipid on the surface and blood oxygen saturation (SO2). We verified the SO2 measurement accuracy by comparing with commercial i-STAT devices for SO2 distribution imaging. At the same time, the segmentation of lipid regions was also tested. Our results demonstrate that this multiparameter phantom is a versatile tool that can facilitate validation and evaluation of multispectral endoscopic systems.
