Document Type and Number:
Japanese Patent JP3267625
Kind Code:
B2
Abstract:
Method and apparatus for reflected imaging analysis. Reflected imaging is used to perform non-invasive, in vivo analysis of a subject's vascular system. A raw reflected image (110) is normalized with respect to the background to form a corrected reflected image (120). An analysis image (130) is segmented from the corrected reflected image to include a scene of interest for analysis. The method and apparatus can be used to determine such characteristics as the hemoglobin concentration per unit volume of blood, the number of white blood cells per unit volume of blood, a mean cell volume, the number of platelets per unit volume of blood, and the hematocrit. Cross-polarizers can be used to improve visualization of the reflected image.
