ABSTRACT
Considering that the patients would bear the annoyance of fixed posture for long time when they are examined with gastrointestinal wireless endoscopy, even though portable devices have been developed, the treatments still depend on PC so much, we proposed an embedded solution based on ARM + FPGA. It used embedded ARM9 S3C2440 as processor core, collected images from digestive tract through capsule endoscopy which can be swallowed down there, and wirelessly transferred these images to the receiving system, then used video decoder chip SAA7114H for analog of NTSC video image decode. And under FPGA's logic controlling, effective digital video signal was transferred to S3C2440 for further treatment. Finally within the embedded Linux environment, we programmed the visual user interfaces using the QT/Embedded, realizing the offline record of the real-time video images of digestive tract portable and preferences. It can make patients move more freely and even without PC when examining. In addition, the method greatly improves the efficiency of the doctor, and is more intelligent and with more humane nature.
