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: a. scanning the beam of light over a region of the eye via the sample arm; b. combining the light from the sample and reference arms; c. measuring the combined light to generate three dimensional volume image data of the eye; d. identifying a first surface within the image data; e. identifying a subvolume of the image data, said subvolume having less than all the generated image data, said subvolume being identified based upon the identification of the first surface, said subvolume being either bounded by or including the first surface, said subvolume including the anatomical region; f. 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; g. generating an image based on information associated with the selected set of image points; and h. storing or displaying the image.
