Optical architecture design for detection of absorbers embedded in visceral fat

Abstract

Abstract:Optically absorbing ducts embedded in scattering adipose tissue can be injured during laparoscopic surgery. Non-sequential simulations and theoretical analysis compare optical system configurations for detecting these absorbers. For absorbers in deep scattering volumes, transillumination is preferred instead of diffuse reflectance. For improved contrast, a scanning source with a large area detector is preferred instead of a large area source with a pixelated detector. 1285-1302 (1998). 15. D. Contini, F. Martelli, and G.
