Demonstration of 3-band spatial frequency domain imaging using an 8-tap CMOS image sensor resistant to subject motion and ambient light

Abstract

We demonstrate three-wavelength spatial frequency domain imaging (SFDI) of a moving arm under a room light with suppressing motion artifact and biased reflectance based on an 8-tap CMOS image sensor developed in our research group. The images for two projected patters for three wavelengths and that for only ambient light are captured. Three LEDs with the wavelengths of 660nm, 780nm, and 850nm were utilized to decompose the oxy-/ deoxyhemoglobin and melanin concentrations. The exposure time for each frame was 70ms. The total hemoglobin, tissue oxygen saturation, and scattering coefficient maps were obtained without any significant motion artifact.
