Improving radiation oncology using a low-cost wireless accelerometer

摘要: Born on military applications, wireless sensor networks span over to different application fields, namely eHealth and medical applications. In this paper we discuss a high-precision, non-intrusive, wireless, accelerometer-based patient movement monitoring system (APMMS) in determining positional change patients undergoing radiation treatment. Using small accelerometer is placed patient's skin, broadcasting its precise position the receiving station connected PC control area. A threshold-based algorithm developed identify exact amount of direction. Our results indicate that, spite low-cost simplicity, APMMS highly sensitive offers accurate measurements.
