Abstract
Near-infrared (NIR) optical imaging systems are developed in an effort to maximize signal to noise ratio (SNR). Recently, a SmartPhone Oxygenation Tool (SPOT) was developed to obtain tissue oxygenation maps from dual-wavelength NIR images. Herein, several noise removal techniques are implemented to the NIR data obtained with SPOT in an effort to improve SNR for low-cost effective imaging of tissue oxygenation maps. NIR and oxygenation changes obtained from standard occlusion studies on normal subjects are compared with and without the noise removal techniques and the improvement in SNR is assessed.
