AI-empowered Wireless Endoscopic Capsule

The advancement of technology has paved the way for medical innovations that have revolutionized the healthcare industry. One of the latest and most promising developments is the Intelligent Wireless Capsule Endoscopy. Gastrointestinal (GI) tract diseases have become a significant health concern globally, with colorectal cancer being one of the leading causes of mortality. However, the low screening rate is due to the limitations of existing solutions. The Intelligent Wireless Capsule Endoscopy is a game-changer as it features cutting-edge technologies that address the shortcomings of traditional endoscopy procedures. 

To address these challenges, we have developed an innovative solution that employs the latest advances in artificial intelligence (AI) technology to improve early detection of GI tract diseases. Our solution is an AI-empowered wireless video endoscopic capsule that outperforms existing alternatives in several keyways.

Firstly, our capsule features real-time image processing using onboard deep neural networks (DNNs), which enable highly accurate and efficient analysis of endoscopic images. Secondly, we have integrated both white-light and narrow-band imaging to enhance the visualization of the mucous layer, which can help identify early signs of disease. Thirdly, our capsule allows for on-the-go task modification and DNN updates using over-the-air-programming, enabling continuous improvements and updates to be made as new data become available. Finally, the capsule can communicate bi-directionally with a patient's personal electronic devices to report important findings, enhancing patient engagement and allowing for better tracking of disease progression.

We tested our solution in vivo by administering our endoscopic capsule to a pig under general anesthesia. We successfully validated all the novel features on a single platform. Our study sets the foundation for the clinical implementation of a new generation of endoscopic capsules that will significantly improve early detection of upper and lower GI tract diseases. By harnessing the power of AI and advanced imaging technologies, we believe that our solution can help reduce the global burden of GI tract diseases and improve patient outcomes.


Integrated HIFU Drive System on a Chip for CMUT-Based Catheter Ablation System

The integrated HIFU (high-intensity focused ultrasound) drive system on a chip is a cutting-edge technology that promises to revolutionize catheter ablation systems. This system consists of a CMUT (capacitive micro-electromechanical transducer) array that can emit high-intensity ultrasound waves, and an integrated circuit that drives the array. The use of a single chip to control the entire system makes it smaller, more efficient, and easier to control.

This technology can potentially offer higher precision and accuracy during catheter ablation procedures, as well as shorter procedure times, fewer complications, and faster recovery times for patients. With the development of the integrated HIFU drive system on a chip, the future of catheter ablation systems is looking brighter than ever.

In this project, an 8-element capacitive micromachined ultrasound transducer (CMUT) ring array of 2 mm diameter has been used as the ultrasound source. This ring array is capable of generating focused ultrasound energy that can be directed to the targeted tissue without affecting the surrounding areas.

The driver chip used in the Integrated HIFU Drive System is fabricated in 0.35 μm high-voltage CMOS technology. The chip comprises eight continuous-wave (CW) high-voltage CMUT drivers that can generate a high voltage pulse. The CW drivers are designed to provide precise and stable control of the ultrasound energy delivery during the ablation procedure.
