Result analysis. The line plot a shows the PCK within deviation threshold of (4, 6, 8, 10, 12) pixel. When the threshold is set to greater than 6, the accuracy will increase slowly and keep at a high level. The accuracy of single landmark estimation is generally higher than that of multiple landmarks. The box plot b shows the deviation for estimating different landmarks in images produced in different way. Our model works especially well when estimating tracheal bifurcation, and basically maintains a 0 deviation estimate. The performance on MV-DRs and KV-DRRs at the same landmark is similar, but there are less large deviations on KV-DRRs
