Error propagation in quantitative biplane cineroentgenography.

The propagation of errors in quantitative biplane cineroentgenography was investigated to see which variables were the most critical. The analysis was carried out both for the propagation of root-mean-square errors and for errors as derived by a Taylor expansion of the reconstruction equations. The reconstruction is most sensitive to the measured values of the coordinates, as opposed to the parameters of the physical system. It was found that decreasing the error in one parameter to zero does not significantly affect the accuracy of the reconstruction; it is more efficient to reduce the errors for all of the parameters simultaneously.
