Method to improve the performance of reflectance diffuse optical...

In order to improve the performance of reflectance diffuse optical imaging (rDOI), a novel polynomial geometry (PG) of optical fibers arrangement is proposed. Polynomial geometry is based on the hexagonal geometry (HG) and multicentered double-density (MD) mode. The overlapping sensitivity matrix, area ratio (AR), reconstruction image, two-absorber model, and contrast-to-noise ratio (CNR) in different depths are used to evaluate the performance of PG. The other three geometries including HG, rec
