Devices. 2014;8(4):041010-041010-10. doi:10.1115/1.4027617 Figure Legend: Top: Orientation angles of Table 1 and cochlear-view axes (lines cv1 and cv2) are shown relative to the three orthogonal reference planes of the body: the sagittal plane (SP), coronal plane (CP), and the transverse plane (TP). θ3 is measured in the plane formed by cv1 and cv2; modified public domain image. Bottom: cochlea orientation angles (shown as a series of successive rotations of a Cartesian frame originally aligned with the reference planes).
