説明

We developed a novel system for imaging and qualitatively analyzing the surface vessels using nearinfrared (NIR) radiation using tuned aperture computed tomography (TACT®). The system consisted of a NIRsensitive CCD camera surrounded by sixty light emitting diodes (with wavelengths alternating between 700 or 810 nm). This system produced thin NIR tomograms, under 0.5 mm in slice thickness. The venous oxygenation index reflecting oxygen saturation levels calculated from NIR tomograms was more sensitive than that from the NIR images. This novel system makes it possible to noninvasively obtain NIR tomograms and accurately analyze changes in oxygen saturation. © 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).
