Endoscopic capsules, ingestible pill-shaped devices designed to capture images from inside the digestive tract, have been around for quite a while. But Sayaka, an endoscopic capsule developed by RF System Lab in December 2005, has dramatically increased the overall image quality by changing the camera position and enabling the camera to rotate.On a typical 8-hour, 8-meter (26 feet) journey through the gastrointestinal tract, Sayaka snaps approximately 870,000 photos, which are sent to a receiver located near the body. Image mosaicking technology is then used to stitch the images together into a flat, high-resolution rectangular map of the intestines, which can be magnified up to 75 times. In addition to scouring the maps for problem areas, gastroenterologists can compare maps from previous sessions to track changes in a patients condition. Saturday, April 30, 2011
