Abstract

A novel diagnostic imaging device based on the transmission of laser light has produced its first clinical image, of an adult forearm. The instrument makes very precise measurements of the time taken for near-infrared (NIR) photons to travel through the tissue. These data, which provide greater sensitivity to internal structure than conventional intensity measurements, are used to compute images tomographically which represent the internal distribution of scattering and absorbing properties. The measurements reported here represent part of a program of preliminary tests prior to use of the instrument to image oxygenation in the brains of newborn infants.
