METHOD AND APPARATUS FOR QUANTITATIVE IMAGING OF BLOOD PERFUSION IN LIVING TISSUE

摘要

Embodiments provide methods and systems for imaging, and, more specifically, to a method and apparatus for quantitative imaging of blood perfusion in living tissue. Some embodiments are directed to methods of obtaining quantitative imaging of blood perfusion in living tissues using Doppler optical micro-angiography (DOMAG).

主权项

1. A method of quantifying blood perfusion in a living tissue sample, comprising:
obtaining an optical microangiography (OMAG) image of a sample, wherein the image has an OMAG background sample; digitally reconstructing a homogeneous ideal static background tissue; replacing the OMAG background sample with the digitally reconstructed homogeneous ideal static background tissue; correlating two or more neighboring A-lines with the digitally reconstructed homogeneous ideal static background tissue; and measuring a phase difference between the two or more neighboring A-lines to quantify blood perfusion in the sample.
