First Claim
Patent Images
1. A method for measuring accumulated cholesterol in tissue, comprising:
- emitting light of two or more wavelengths toward a skin sample such that the light is differentially absorbed by plated or platable cholesterol in the skin sample;
detecting the differentially absorbed light; and
determining the amount of plated or platable cholesterol in the skin sample based on the differential absorption.

Abstract
A method and apparatus is provided for measuring a sterol, such as cholesterol, deposited in the skin. Light of two or more wavelengths is emitted toward or into a skin sample and the light is differentially absorbed by the sterol in the skin sample. The differentially absorbed light is detected and the amount of sterol in the skin sample is determined based on the differential absorption.

9. A system for measuring accumulated cholesterol in tissue comprising:
-
one or more light emitters each configured to emit light at one or more wavelengths such that the combined one or more light emitters emit light at two or more wavelengths; one or more light detectors configured to detect the light; and a processor configured to receive the detected light and to determine an amount of plated or platable cholesterol in the skin based on differential absorption of the light. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A system for measuring a sterol deposited in the skin comprising:
-
one or more light emitters each configured to emit light at one or more wavelengths such that the combined one or more light emitters emit light at two or more wavelengths; one or more light detectors configured to detect the light; and a processor configured to receive the detected light and to determine an amount of a sterol deposited in the skin based on differential absorption of the light; one or more optically transmissive structures in optical communication with at least some of the one or more light emitters and/or the one or more light detectors, wherein the one or more optically transmissive structures are configured to penetrate the surface of an in vivo skin sample. - View Dependent Claims (18, 19)
