The effects of deviations in geometric parameters on the accuracy of calculating three-dimensional coordinates in fluoroscopic navigation systems
摘要
Three-dimensional cardiac mapping is an integral part of the visualization system in the treatment of arrhythmia. However, X‑ray fluoroscopic systems are the main method for monitoring visualization, though they allow only two coordinates of the instrument to be determined. The work reported here models the influence of error in the geometric parameters of the support on determination of the three-dimensional coordinates of an object. The simulation results show that a 1% geometric distortion leads to a 10% decrease in accuracy in the working area.
