Given Imaging PillCam ESO (http://rbi.ims.ca/4919-541). About the size of a multi-vitamin, this disposable medical capsule has miniature cameras on both ends. Instead of sedating the patient to perform a traditional Endoscope probe of the esophagus, the patient simply swallows the pill. During its five minute journey, the cameras flash approximately 14 times per second taking about 2,600 color pictures, which are transmitted to a recording device worn by the patient. Size was one of the most important criteria, so engineers chose a proprietary bare die CMOS imaging chip from Micron Technology.
