Efficacy Evaluation of SAVE for the Diagnosis of Superficial Neoplastic Lesion.

The detection of non-polypoid superficial neoplastic lesions using current standard of white light endoscopy surveillance and random biopsy is associated with high miss rate. The subtle changes in mucosa caused by the flat and depressed neoplasms often go undetected and do not qualify for further investigation, e.g.

Routing over multi-hop fading wireless body area networks with reliability considerations.

Optimal reliable routing is studied in the context of fading wireless body area networks (WBANs). A non-cooperative game is proposed to model and analyze the strategic interactions among body-worn health-care devices when each seeks to find the most reliable path to the hub. A distributed algorithm based on the proposed game is provided and proved to converge to a multi-hop Pareto-dominant Nash topology.

An RF-based wearable sensor system for indoor tracking to facilitate efficient healthcare management.

To understand the utilization of clinical resources and improve the efficiency of healthcare, it is often necessary to accurately locate patients and doctors in a healthcare facility. However, existing tracking methods, such as GPS, Wi-Fi and RFID, have technological drawbacks or impose significant costs, thus limiting their applications in many clinical environments, especially those with indoor enclosures. This paper proposes a low-cost and flexible tracking system that is well suited for operating in an indoor environment.
