A Proposal to Perform High Contrast Imaging of Human Palatine Tonsil with Cross Polarized Optical Coherence Tomography
نویسندگان
چکیده
The palatine tonsils provide the first line of immune defense against foreign pathogens inhaled or ingested. However, a disruption in epithelial layer within tonsil crypts can lead to recurrent acute tonsillitis (RAT). Current imaging techniques suffer from poor resolution and contrast do not allow classification severity RAT. We have developed cross-polarized optical coherence tomography system. system detect change polarization light after light-tissue interaction. demonstrate improved with method. Intensity, as well retardance images excised tissue, were acquired. Features such crypt epithelium, lymphoid follicles, dense connective tissue observed contrast. Cross polarized be valuable tool clinic evaluate it would visualizing common features without need for any external agent.

Optical Coherence Tomography and Autofluorescence Imaging of Human Tonsil
For the first time, we present co-registered autofluorescence imaging and optical coherence tomography (AF/OCT) of excised human palatine tonsils to evaluate the capabilities of OCT to visualize tonsil tissue components. Despite limited penetration depth, OCT can provide detailed structural information about tonsil tissue with much higher resolution than that of computed tomography, magnetic re...

We demonstrate an application of high-speed swept source optical coherence tomography for vessel visualization in the anterior segment of the human eye. The human corneo-scleral junction and sclera was imaged in vivo. Imaging was performed using a swept source OCT system operating at the 1050nm wavelength range and 100kHz A-scan rate. High imaging speed enables the generation of 3D depth-resolv...

Phase variance-based motion contrast imaging is demonstrated using a spectral domain optical coherence tomography system for the in vivo human retina. This contrast technique spatially identifies locations of motion within the retina primarily associated with vasculature. Histogram-based noise analysis of the motion contrast images was used to reduce the motion noise created by transverse eye m...
