This causes a permanent magnet to turn the inner capsule and the image sensor 60 degrees every two seconds.

Offload data: Instead of storing each two-megapixel image internally, Sayaka continually transmits shots wirelessly to an antenna in the vest, where they are saved to a standard SD memory card. Deliver video: Doctors pop the SD card into a PC, and software compiles thousands of overlapping images into a flat map of the intestines that can be as large as 1,175 megapixels. Doctors can replay the ride as video and magnify a problem area up to 75-fold to study details. Leave the body: At around $100, the cam is disposable, so patients can simply flush it away.
