Near-Infrared Fluorescence Optical Imaging and Tomography

The advent of recent advances in near-infrared laser diodes and fast electro-optic detection has spawned a new research field of diagnostic spectroscopy and imaging based on targeting and reporting exogenous fluorescent agents. This review seeks to concisely address the physics, instrumentation, advancements in tomography, and near-infrared fluorescent contrast agent development that promises s...

Optical/Near-Infrared Imaging of Infrared-Excess Palomar-Green QSOs

Ground-based high spatial-resolution (FWHM < 0.3–0.8) optical and nearinfrared imaging (0.4—2.2 μm) is presented for a complete sample of optically selected Palomar-Green QSOs with far-infrared excesses at least as great as those of “warm” AGN-like ultraluminous infrared galaxies (Lir/Lbig−blue−bump > 0.46). In all cases, the host galaxies of the QSOs were detected and most have discernable two...

Near-infrared optical imaging of proteases in cancer.

Near-infrared optical imaging is a newer imaging technique that, coupled with sensitive enzymatically specific fluorescent beacons, shows much promise for earlier detection of many cancers and their in situ characterization. On the basis of animal studies demonstrating visualization of micrometastasis-sized tumors and the ability to evaluate therapeutic enzyme inhibition real-time, such imaging...

Dynamic multichannel near-infrared optical imaging of human brain activity.

The present paper demonstrates functional brain mapping with an optical imaging technique by using tissue-transparent near-infrared light. With a maximal five-channel optical monitoring system, we succeeded in detecting region-specific changes in both the hemoglobin oxygenation state and blood volume during various mental tasks, in addition to visual and auditory stimulation. The time course of...
