Abstract
A method and apparatus for determining properties of a tissue or tissues imaged by optical coherence tomography (OCT). In one embodiment the backscatter and attenuation of the OCT optical beam is measured and based on these measurements and indicium such as color is assigned for each portion of the image corresponding to the specific value of the backscatter and attenuation for that portion. The image is then displayed with the indicia and a user can then determine the tissue characteristics. In an alternative embodiment the tissue characteristics is classified automatically by a program given the combination of backscatter and attenuation values.
Claims15
A processor-implemented method for identifying tissue components in situ comprising the steps of:
- collecting an optical coherence tomography (OCT) dataset of a tissue sample in situ using a probe;
- measuring attenuation values and backscattering values at points in the tissue sample;
- and
- determining a tissue characteristic at locations in the tissue sample corresponding to image locations in an OCT image formed from the OCT dataset, wherein the tissue characteristic is based on a combined mapping of the attenuation values and the backscattering values for each location in the tissue sample.
