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.
Claims20
A method for determining the area and/or volume of a region of interest of a biological tissue using optical coherence tomography (OCT), the method comprising:
- a) acquiring three-dimensional OCT data comprising at least a first segment and a second segment comprising the region of interest;
- b) acquiring two-dimensional image data comprising the region of interest;
- c) providing a boundary around the region of interest in the two-dimensional image data, the boundary enclosing an area A;
- d) calculating the volume v within the boundary and between the first segment and the second segment;
- e) calculating the average thickness t between the first segment and the second segment along the boundary;
- and
- f) calculating the volume of the region of interest V=v−(t×A).
