Or, more accurately, Ng found himself thinking about how he could use similar theatre- quality 3-D imagery to improve the level ofcarehewasprovidingtothepatientshe sees as a certified specialist in oral medi- cineandpathologyinVancouver. “From the clinical perspective,” Ng said, “it’s easier for me to keep track of changesinthelesionwith3-D.Itactually helps me to see things better than with only a 2-D view. It’s a much better way to capture the morphology or the topo- graphicappearanceofthelesion.WhenI lookatthelesionin3-D,I’mabletoappreci- atethefissuremuchbetter.” Five years ago, before his “aha moment” while watching “Avatar” through his movie-house 3-D glasses, Ng had already developed strong photog- raphy skills documenting the many hun- dreds of cases that have been referred to himovertheyears. After“Avatar,”Ngstartedresearching 3-Dphotography.Informationwasbounti- ful,untilitcametohisspecificchallenge: applying the technology to clinically capturing 3-D images of lesions in often- difficult-to-accessareasofthemouth. In the beginning, there was a lot of By Robert Selleck, Managing Editor trialanderror,especiallywiththevisual- effect projection, mathematical equa- tionsandbiomedicalengineeringneeded togetthe“right-eye”and“left-eye”images to correctly capture and then merge into perfectly clear, perfectly focused real- world depictions of lesions. Another big challenge was figuring out exactly how thelightingneededtobesetup—andset- tingitupquicklyintheclinic. ButNggotbetterfast,alwaysensuring the process was virtually invisible to his patient in terms of never requiring any greater time or inconvenience than his standard2-Dphotos. Amateurtoproinfiveyears To capture the 3-D images, Ng uses two cameras or, depending on location of the lesion, a special 3-D lens. He uses 3-D instead of 2-D on about half of his cases — whenever he thinks an outcome will benefit from having a 3-D perspective as partofthediagnosticrecord. Today, five years later, his amateurish beginnings have evolved into a sophis- ticated process of 3-D documentation, and he has amassed a stunning archive of super-high-definition 3-D images depicting a vast array of lesions at mul- tiplestagesofdevelopment.
