Conformance of automatically defined trajectory centerlines and screw plans within bone corridors in the leave-one-out study over 40 cases. (a) Heatmap probability distribution of the distance of the planned trajectory centerlines to the pedicle cortex as a function of distance along the trajectory. The solid blue line indicates the median distance, and the dashed blue lines indicate the interquartile range. Red markers indicate breaches of the cortical wall. (b) Violin plots of the minimum distance of planned screws to the medial, lateral, superior, and inferior cortical walls, along with GB classifications.
