Model for 3D Optical Imaging of Tissue

R. L. Barbour et al. (1990)


A potential imaging scheme is described which considers use of reflected radiation at near infrared frequencies and is intended for use in a broad spectrum of clinical applications. For clinical studies the object is to detect and locate regions of anomalous absorption which yield information about physiological function. Using Monte Carlo procedures to simulate the process, the relations between detector response and the paths of contributing photons were calculated. This information was then processed using a backprojection scheme to compute 3D images of random media containing discrete absorbers (simulating tissue). The current report demonstrates the feasibility of 3D imaging of subsurface structures in random media based on the analysis of diffusely scattered light.
