First Claim
Patent Images
1. A device for imaging a sinus cavity of a patient, the device comprising:
- a flexible illuminator configured to conform to the patient'"'"'s upper palate;
an optical output located on a distal end of the flexible illuminator, wherein the optical output is configured to direct radiation towards the patient'"'"'s sinus cavity;
an optical detector configured to receive the radiation from the optical output that passes through the patient'"'"'s sinuses and out the patient'"'"'s tissue, and provide a output signal; and
an analyzer configured to create an iso-intensity line map from the output signal.

Abstract
Disclosed herein are embodiments of a device and method for near-infrared imaging of a patients sinus cavities. The imaging can be used for diagnosis and monitoring of different conditions such as maxillary sinusitis. The system and method can use LEDs to provide near-infrared light through the tissue of a patient, where the light can be picked up by a camera. An iso-intensity contour line map can then be created for quantitative analysis.
