Oops! I Swallowed a 3D Camera (video)
StereoscopyNews.com reports that a new technique developed by Massachusetts General Hospital (MGH) to diagnose oesophagial cancer uses a minuscule 3D camera you can swallow with a glass of water.
Just about the size of a US penny, this tiny tethered camera can be lowered and raised in the patient’s esophagus to allow a complete stereoscopic 3D picture (and a full 3D CGI model) to be captured. Using optical frequency domain imaging (OFDI), the small camera is supplemented with an infrared beam to view the tissue. Spinning at 20Hz, this hair-sized beam of light gives the doctor a 360° macroscopic view of the esophagus.
