An Experience Sharing: A Panoramic-Vision Lesion-Finding Low-Power Wireless Endoscopic System Design and Implementation
DescriptionThe limited field-of-image and lesion-position-losing of the endoscope are often the most problematic issues faced by junior surgeons. A battery-operation wireless four-lens panoramic endoscopy is proposed. This design provides a panoramic vision and in-time lesion-guiding information during a surgical operation. This work consists of a combination of several image-processing techniques of image-stitching, viewing-synthesis, and lesion-guiding to a view. Lesion-guiding provides global positioning information and tracks the predefined lesion position during surgery. On the low-power hardware design system, the image-processing encoder and decoder chips were designed using the clustered voltage-domain technique. The technique of the designed chip is separated by two/four voltage domains, and the voltage-scaling technique is used for each domain. The high-voltage domain maintains the chip performance, and the low-voltage domain reduces the power consumption. This effective technique decreases the power consumption without reducing the performance of the chip. The entire system is integrated by a personal computer, an embedded system, and image encoder+decoder chips. By applying the Multi-Vdd technique, the multiple-Vdd encoder and decoder chips can be quickly redesigned based on the power, delay-time, and gate-count optimization requirements. The power consumption of the encoder and decoder chip can be effectively reduced to 50% and 24%, respectively. The performance loss can be maintained within 5% of both designs. A wireless panoramic endoscopic system is successfully validated and demonstrated by integrated encoder and decoder chips. The whole system has been successfully validated by animal in-vivo experiments. Experimental results show that the proposed system can enhance the side-by-side image size to 155%. Based on our search, there is no similar work that can be used as a comparison.
