Digital Eversion of a Hollow Structure: An Application in Virtual Colonography
Figure 6
Surface rendering of the original colon lumen with two
digitally implanted polyps and its reference surface for digital eversion. (a) An
outside view of the whole colon lumen, in which the portion defined by the
frame is selected for the digital eversion, (b) a magnified view of the
selected colon segment and the simulated polyps (arrows), (c) a magnified view
of (b), (d) a bisected colon to show the inner surface and the simulated polyps
(arrows), (e) a magnified view of (d), and (f) the reference surface for the digital
eversion.
