<p>A device, system and method for obtaining in vivo images from within a body lumen, such as the gastrointestinal tract. Figure 1 shows a swallowable capsule (40) for obtaining image data. The swallowable capsule (40) includes an imager (46), a processor (47), and an illumination source (42), suitable for illuminating a body cavity. The apparatus also includes an optical system (50), which may incorporate lenses and filters, for the purpose of focusing light into the imager (46). Images are transmitted, via a transmitter (41) and an antenna (48), and are compressed by the compression module (600), to reduce bandwidth. The transmitter (41) further includes a power source (45), such as silver oxide batteries, lithium batteries, or other electrochemical cells. The transmitter also includes a modulator (70), an amplifier (72), and an impedance matcher (74). The receiver (12) receives compressed image data through an antenna (15), and stores it in a storage unit (16). The receiver is small, and may be worn on a patients body. The receiver also includes a data processor (14). Preferably the data processor (14), its data storage unit (19), and a monitor (18), are part of a personal computer, or workstation, which includes a CPU (13). Once data is received, it is decompressed, via a decompression module (610), and processed for display.</p> |
