This picture, titled "What Lies Behind Our Nose?", won a tie for first in the 2007 International Science & Engineering Visualization Challenge. Dr. Kai-hung Fung of Pamela Youde Nethersole Eastern Hospital in Hong Kong created the stunning image by taking computed tomography (CT) scans of a patient he examined for thyroid disease. Stacking nearly 200 CT slices yielded this image, which looks up at the sinus cavity from below the head.
