<i>Novel System Designs and Molecular Contrast in Optical Coherence
Tomography<br>
</i>Optical Coherence Tomography (OCT) is a novel biomedical imaging
technique which uses low-coherence optical interferometry to obtain
micron-scale resolution tomographic images of sub-surface tissue
structure noninvasively. We have developed OCT scanners compatible with
minimally invasive delivery technologies (i.e., biomicroscopy, endoscopy)
capable of imaging up to video rate. Clinical studies of OCT imaging in
the eye, skin, and gastrointestinal tissues are under way which
demonstrate reproducible image contrast between morphological tissue
layers, as well as differentiation between normal and abnormal tissue
regions. We have also demonstrated OCT applications for noninvasive 3D
imaging in embryos and small animals. We report on dramatic recent
technical advances in OCT which have significantly enhanced its
capability for minimally invasive clinical diagnostics and for basic
biological research. These include system designs which achieve a
significant SNR advantage through parallel detection, as well as the
first demonstrations of molecular imaging with OCT.<br><br>
