Claim 18:
19. An apparatus for designating a location of an optical coherence tomography (OCT) scan, by an OCT scanner, to be performed on a retina of an eye, the apparatus comprising:
a display device configured to display an image comprising a background image of a portion of the retina and a foreground graphical planning element for designating a location on the retina of the OCT scan to be performed;
a touch-sensitive input device having a touch-sensitive surface and configured to generate respective touch interaction data indicative of at least one sequence of detected locations for each of a plurality of touch interactions of a user with the touch-sensitive surface;
a computer processor and a computer-readable storage medium storing instructions, wherein the instructions, when executed by the computer processor, cause the computer processor to:
determine, based on each of the touch interaction data, one or more image manipulations to be performed on at least one image currently being displayed by the display device, at least one of the image manipulations comprising at least one of:
a concurrent resizing of both the foreground graphical planning element and the background image by a common factor, while maintaining a location and orientation of the foreground graphical planning element with respect to the background image and without having moved the OCT scanner, wherein the concurrent resizing occurs in response to a touch interaction with the touch sensitive surface that selects only the background image, or
a planning of the image being displayed, the panning including commonly translating both the foreground graphical planning element and the background image while maintaining the location and orientation of the foreground graphical planning element with respect to the background image throughout the panning, wherein the panning is performed in response to a touch interaction with the touch sensitive surface that is outside of a predetermined distance from the foreground graphical planning element and which is the beginning of a drag operation;

apply the at least one image manipulation to the image currently being displayed on the display device so as to generate a respective updated image that is to be displayed on the display device; and
generate OCT scan location data indicative of the location of the OCT scan that is to be performed on the retina based on a location of the foreground graphical planning element on the background image of the retina in at least one of the updated images.
