Anthropomorphic tissue-mimicking phantoms for oximetry validation in multispectral optical imaging

Le résumé fourni par la source

Significance: reference standards, including test objects. Aim: by introducing anthropomorphic phantoms with appropriate tissue-mimicking optical properties. Approach: We used the stable copolymer-in-oil base material to create physical anthropomorphic structures and optimized dyes to mimic the optical absorption of blood across a wide spectral range. Using 3D-printed phantom molds generated from a magnetic resonance image of a human forearm, we molded the material into an anthropomorphic shape. Using both reflectance hyperspectral imaging (HSI) and photoacoustic tomography (PAT), we acquired images of the forearm phantoms and evaluated the performance of linear spectral unmixing (LSU). Results: assessment with HSI and PAT. Conclusions: .
