Abstract

Regular blood lipid screening is recommended for early diagnosis of cardiovascular diseases. We present a portable LED based SFDI system as a new clinical tool for non-invasive blood lipid monitoring. The new SFDI system was used to measure changes in optical properties within subcutaneous blood vessels on subjects’ dorsal hands after consumption of a meal. Superficial blood vessels were segmented and a two-layer inverse model was used to incorporate the effects of overlying skin. The results show an increase in μ_s^' and a decrease in μ_a at around 3h after the meal, followed by a gradual return to baseline values.
