In vivo surface reconstruction examples
( N.B. - These surface displays use splatting of points rather than a surface
triangulation.)
These examples are from ultrasound scans recorded at Addenbrookes Hospital,
Cambridge. In each case, about 20 scans were used to reconstruct the surface
of the organ. This reconstruction only takes 10 seconds or so on a modern
computer. Click on the surface reconstructions to see a video of the rotating surface.
