Multimodality molecular imaging is becoming more and more important to understand both the structural and the functional characteristics of tissue, organs and tumors. So far, invasive nuclear methods utilizing ionizing radiation have been the ldquogold standardrdquo of molecular imaging. We investigate non-contact, non-invasive, patient-tolerant and inexpensive near infrared (NIR) frequency domain...
Two systems were used for imaging. The first was a combined optical coherence tomography(OCT)/laser induced fluorescence(LIF) instrument, with a 1310 center wavelength OCT source and a 633 nm He:Ne laser for excitation of the Cy5.5 dye. The OCT and LIF channels were combined into a 2 mm diameter endoscope.
The article consists of a Powerpoint presentation on optical technologies for early GI cancer detection. The areas discussed include: optical diagnostics; white-light endoscopy; optical coherence tomography; microendoscopy; endocytology; fluorescence endoscopy; Raman spectroscopy; confocal microscopy; diffuse reflectance spectroscopy and elastic scattering spectroscopy etc. etc.
