A wireless sensor system has been implemented to augment X Ray dose tracking capabilities in real time. The main application of this project is to develop a tilt and heading measuring unit to measure the angular change in position of the X-Ray C-Arm unit. The C-Arm exhibits 5 degrees of freedom with three being compound rotational and two being translational. The system thus developed shall be able to transmit this data to the host computer through a wireless medium. The dose tracking application shall process this information, as mandated by the software to graphically depict the position of the C-Arm on the user interface. Two boards for the transmitter and receiver were fabricated and set up. A low-g accelerometer was used to measure the tilt on the machine. This accelerometer was embedded onto the transmitter which was then placed on the C-Arm to measure its tilt. A digital magnetic sensor was also incorporated to provide information on the heading of the C-Arm. The main advantages of this system are cost, precision and accuracy. In addition to these benefits there will also be considerable reduction in the exposure levels for operators, since, a wireless transmission of data would substantially reduce operator presence in the X-Ray room. This report elaborates on the principle, design, and developed circuit description, results and applications.
