Results of the phantom evaluation of algorithmically determined parameters versus ground truth. Boxes indicate upper and lower quartile and median, diamonds indicate mean, and maximum and minimum are indicated by whiskers. a Difference in translation. b Difference in rotation. c Difference in CT numbers measured in regions of interest (ROIs) before correction. d Difference in CT numbers measured in ROIs after correction. Note the different quantities and units and the different scaling of the y-axes
