A non-invasive imaging and analysis system suitable for measuring concentrations of specific components, such as blood glucose concentration and suitable for non-invasive analysis of defects or malignant aspects of targets such as cancer in skin or human tissue, includes an optical processing system which generates a probe and composite reference beam. The system also includes a means that applies the probe beam to the target to be analyzed and modulates at least some of the components of the composite reference beam such that signals with different frequency content are generated. The system combines a scattered portion of the probe beam and the composite beam interferometrically to simultaneously acquire information from multiple depths within a target. It further includes electronic control and processing systems.

Evaluating tissue characteristics including identification of injured tissue or alteration of the ratios of native tissue components such as shifting the amounts of normal myocytes and fibrotic tissue in the heart, identifying increases in the amount of extracellular components or fluid (like edema or extracellular matrix proteins), or detecting infiltration of tumor cells or mediators of inflammation into the tissue of interest in a patient, such as a human being, is provided by obtaining a first image of tissue including a region of interest from a first acquisition, for example, after administration of a contrast agent to the patient, and obtaining a second image of the tissue including the region of interest during a second, subsequent acquisition, for example, after administration of a contrast agent to the patient. The subsequent acquisition may be obtained after a period of time to determine if injury has occurred during that period of time. The region of interest may include heart, blood, muscle, brain, nerve, skeletal, skeletal muscle, liver, kidney, lung, pancreas, endocrine, gastrointestinal and / or genitourinary tissue. A global characteristic of the region of interest of the first image and of the second image is determined to allow a comparison of the global characteristic of the first image and the second image to determine a potential for a change in global tissue characteristics. Such a comparison may include comparison of mean, average characteristics, histogram shape, such as skew and kurtosis, or distribution of intensities within the histogram.

A non-invasive imaging and analysis system suitable for measuring attributes of a target, such as the blood glucose concentration of tissue, includes an optical processing system which provides a probe and reference beam. It also includes a means that applies the probe beam to the target to be analyzed, combines the probe and reference beams interferometrically, detects concurrent interferometric signals and correlates the detected signals with previously stored electronic data to determine the attribute of the target.

A non-invasive imaging device includes an illumination source comprising an incident light source to direct unpolarized light upon skin of a person, the incident unpolarized light having polarization properties including electrical and magnetic properties. The device also includes a detector for detecting light reflected from the skin, the light reflected from the skin of the person having polarization properties including electrical and magnetic properties. A host system coupled to the detector detects differences in polarization properties of the detected light reflected from the skin of the person compared to polarization properties of reflected light from the person at a different point in time and generates an assessment of skin health changes based on the differences.
