Abstract

Systems based on Wireless Sensor Networks (WSN) provide monitoring for a wide range of applications in healthcare. Network nodes take care of data acquisition, processing and transmission and are therefore required to be wireless and low-power. The authors present the first version of the prototype of a portable wireless dosimetric system based on a commercial CMOS image sensor to be used during Interventional Radiology (IRad) procedures. A proprietary data processing and reduction algorithm has been implemented in the prototype. Current consumption of the transmitting unit of the prototype has been measured for battery sizing. Both system response and algorithm performance have been investigated and consistency with results obtained using the same model of CMOS sensor with its own acquisition system provided by the manufacturer has been demonstrated.
