Imaging and insufflation results. Representative image of the USAF resolution target with smallest resolved pattern identified with an arrow (a), distortion target with 2-mm region of unnoticeable distortion identified by the dashed circle (b), the respective distortion curve as a percentage of image height (c), magnification performance as a function of distance (d), image intensity with representative grayscale values at different illumination levels (e), and insufflation performance for various flow rates (f)
