چکیده
Wireless capsule endoscopy is a fast-growing technology in healthcare systems. Due to using battery for powering the camera, light source, wireless communication, and other electronics, it has substantial limitations with image quality, frame rate, operating time. In this work, we propose passive video transmission system endoscopy, which power consumption reduced by analog camera sensor, implementing an innovative radar technique remote reading of signal radio frequency backscattering. The communication tends zero. electronics minimized single Varactor diode appropriate matching circuits sensor eliminating sensor’s digital converter. With these improvements can operate longer period time enables feasibility continuous streaming during gastric tract screening. design demonstrated phantom experiment, validated animal experiment depths 6–11 cm bi-static at 400 MHz, implemented software defined platform.

متن کاملA Video Aided RF Localization Technique for the Wireless Capsule Endoscope (WCE) inside Small Intestine
Wireless capsule endoscope (WCE) provides a noninvasive method to examine the entire gastrointestinal (GI) tract including small intestine, which other video endoscopic instruments cannot reach. Since the shape of small intestine is extremely complex and the length of small intestine varies from 5 to 9 meters, localization of the WCE inside the small intestine is very challenging. Traditional r...
