Fig. 2From: Is vertebral rotation correction maintained after thoracoscopic anterior scoliosis surgery? A low-dose computed tomography studyAn example of a true axial image of the inferior endplate of L1. The large, true axial, image is obtained by modifying the plane of viewing in the frontal and sagittal planes with respect to the smaller images to the left. Rotation in the transverse plane was analysed in relation to the arbitrary CT scanner bed plane, thus allowing the measurement of relative inter-endplate rotations within patientsBack to article page
