1. A method of generating an image of an anatomical region within an eye, said eye being examined by an optical coherence tomography (OCT) system, said OCT system including a light source for generating a beam of light, a sample arm, a reference arm, and a detector for measuring light combined from the sample and reference arms, said method comprising the steps of: scanning the beam of light over a region of the eye via the sample arm; a. combining the light from the sample and reference arms; b. measuring the combined light to generate three dimensional volume image data of the eye; c. identifying a first surface within the image data; d. identifying a subvolume of the image data, said subvolume being identified based upon the identification of the first surface, said subvolume including the anatomical region; e. selecting a set of image points within the subvolume, said image points being selected by evaluating a plurality of ray projections extending through the subvolume and identifying one image point in each projection, wherein each of the identified image points has a common intensity attribute; f. generating an image based on information associated with the selected set of image points; and g. storing or displaying the image.
