Paper Abstract

Diffuse Optical Tomography (DOT) is a new and promising medical imaging modality which uses near-infrared light to probe tissue properties. Using multiple wavelengths of light can provide important information about tissue metabolism and cancer malignancy. Unfortunately, in most DOT acquisition schemes, acquiring data for each wavelength has a multiplicative effect on the overall imaging time. In this paper, we evaluate a new multiple wavelength laser module (Praevium Research Inc.) with 12 laser diodes all coupled to a single output fiber. When used in conjunction with a cooled spectrometer, it allows simultaneous multi-wavelength data acquisition and hence, higher temporal resolution.
