1. A method of rendering for display image data from a forward-looking conical section of tissue collected by an image data collecting device, comprising: receiving the image data from the forward-looking conical section; generating a nutated projected three-dimensional geometric model of the forward-looking conical section, wherein the generating step comprises applying a nutation definition to tilt a three-dimensional geometric model corresponding to the forward-looking conical section; and rasterizing the image data in accordance with the nutated projected three-dimensional geometric model to produce a rasterized image for display on a graphical display.
