Abstract

In this report, we investigate the effects of array density and modulation frequency on spatial accuracy, resolution, and penetration of frequency domain high-density diffuse optical tomography (FD HD-DOT). The result shows that these metrics are improved by using higher array densities or an optimized modulation frequency, while array density is the stronger parameter. Additionally, the improvement of image quality shows diminishing effects with denser arrays.
