Registration accuracy for msLevelCheck in clinical data. (a) Example case showing single-level rigid registration and msLevelCheck output for a case exhibiting an increase in spinal lordosis in the radiograph compared to preoperative CT. Distribution the mean (b) and maximum (c) PDE pooled over cases in the clinical dataset, showing msLevelCheck to improve registration accuracy and recover from cases that might be considered a registration failure.
