Abstract
Provided herein is technology relating to analysis of images and particularly, but not exclusively, to methods and systems for determining the area and/or volume of a region of interest using optical coherence tomography data. Some embodiments provide for determining the area and/or volume of a lesion in retinal tissue using three-dimensional optical coherence tomography data and a two-dimensional optical coherence tomography fundus image.
Claims19
A method for determining the area and/or volume of a lesion in the eye of a patient using optical coherence tomography (OCT), the method comprising:
- scanning the eye of the patient with an OCT apparatus to acquire three-dimensional OCT data comprising at least a first segment and a second segment comprising the region of interest;
- acquiring two-dimensional image data comprising the region of interest;
- providing a boundary around the region of interest in the two-dimensional image data, the boundary enclosing an area A;
- calculating the volume v within the boundary and between the first segment and the second segment;
- calculating the average thickness t between the first segment and the second segment along the boundary;
- calculating the volume of the region of interest V=v−(t×A);
- and
- via a computer processor correlating the two-dimensional and three-dimensional data to quantify the lesion in the eye of the patient.
