Abstract

The shortwave infrared (SWIR) optical window has distinct advantages in terms of improved imaging penetration depth and unique optical contrasts in tissue. Here I will describe two new diffuse optical technologies our research team is developing and extending to the SWIR wavelength band: spatial frequency domain imaging (SFDI) and frequency domain diffuse optical spectroscopy (FD-DOS). I will describe the advantages of these techniques and show clinical data related to applications in which these techniques have been deployed: non-invasive blood lipids monitoring and kidney dialysis monitoring. I will also discuss openSFDI, an open hardware project that provides instructions for groups looking to develop their own SFDI systems.
