Abstract
A method/system preserves annotations of different pathological conditions or changes that are recognized on cross-sections within a three dimensional volume of a patient's eye so that the annotations are maintained in a visible state in an en face projection produced with a SVP technique. it is thus possible to coregister the annotated conditions or changes with other types of two dimensional en face images such as images from other ophthalmic devices (e.g., angiography device, microperimetry device, autofluorescence device, fundal photography device.). The annotations are also maintained in a visible state in the coregistered image.
Claims46
A method comprising:
- receiving, in a computer system, optical coherence tomography (OCT) data;
- generating, using the computer system, first image data corresponding to a summed voxel projection (SVP) of the received OCT data;
- receiving, in the computer system, second image data obtained with at least one ophthalmic device, the second image data representing a data set independent from the OCT data and the first image data;
- and
- coregistrating, using the computer system, the first image data and the second image data to generate coregistered image data.

A method comprising:
- receiving, in a computer system, a plurality of image data sets, each image data set representing an OCT scan and annotation data associated with a part of that represented OCT scan;
- performing, using the computer system, a summed voxel projection (SVP) of the plurality of image data sets to generate a first image having a marking corresponding to the annotation data;
- aligning, using the computer system, the first image with a second image obtained using at least one ophthalmic device, the second image being generated from a data set independent from said each image data set representing an OCT scan;
- and
- superimposing, using the computer system, the first and second images together to generate a third image, the third image having the marking corresponding to the annotation data.

An image processing system comprising:
- a first input that receives optical coherence tomography (OCT) data;
- a second input that receives image data obtained with at least one ophthalmic device, the image data obtained with the at least one ophthalmic device representing a data set independent from the OCT data;
- and
- a processor that performs a summed voxel projection (SVP) of the OCT data to produce SVP image data, and that performs a coregistration process on the SVP image data and the image data received by the second input to generate coregistered image data.
