Abstract:
1. An optical coherence tomography (OCT) system for determining an analyte level in tissue, comprising: a light source for generating skin-penetrating radiation suitable for OCT measurements; a detector for receiving at least a portion of reflected light from the skin-penetrating radiation; a beam scanner configured to direct a beam of radiation from the light source to a plurality of different locations on a two-dimensional region of a skin surface to scan a plurality of different tissue sites associated with each different location; a processor configured to determine a subset of tissue sites that each include an analyte correlating region, wherein an analyte correlating region comprises a tissue site that is valid for measuring an analyte level; and a controller configured to direct the beam scanner to monitor each of the subset of tissue sites determined to include analyte correlating regions, the controller further configured to exclude from monitoring at least a portion of tissue sites determined not to include analyte correlating regions.
