M2A " capsule is of a size of 11mm × 27mm, is made up of light source, lens, CMOS sensitive chip, set of cells and wireless transport module." M2A " capsule is approved by food and medicine committee, and 34 country drop into business application, but " M2A " capsule also exist shooting frame per second low, for some minute lesions easily occur leak clap.
2008, U.S.'s RF system laboratory developed a kind of human body endoscope, " Sayaka " by name.The diameter of " Sayaka " capsule only 9 millimeters, length is 23 millimeters, does not have battery-mounted, passes through wireless power." Sayaka " capsule adopts CCD sensitive chip, per secondly takes 30 pictures, and shooting Image Saving is in the SD of portable receiver end.After being completed, SD card takes out by doctor, after software processes, can form the plane graph of intestinal, is convenient to doctor and observes minutia in intestinal." Sayaka " capsule endoscope is in the experiment test stage at present, also non-commercial applications.
In June, 2004, Chongqing in China Kingsoft science and technology (group) company limited have developed " OMOM " capsule endoscope, and have passed the examination of national " 863 " expert group." OMOM " capsule endoscope diameter is 13mm, and length is 28mm." OMOM " capsule endoscope adopts Passive Mode, and cost compare is high, is difficult to accepted by the public.
