Information layering is provided in medical imaging. Two or more types of information are provided in one image. A three-dimensional surface is formed for two-dimensional scanning and/or imaging. The depth or third dimension is mapped to one type of data. Variation in values of this type of data causes variation in the surface away from flat. Data of another type is mapped to the surface, such that each location having a color or gray scale value based on the other type and a depth based on the one type. The surface is rendered using three-dimensional rendering to show the depth information even though both types of data represent a scanned plane. Stereoscopic viewing may allow the user to better visualize the depth information.
