Morphological findings and measurements of the porcine ET phantom. (a) Axially sectioned CT images of the porcine ET phantom showing the dilated ET in a curved-cone shape. ET lumen consists of the Rüdinger safety canal (arrow) and the auxiliary gap (arrowhead). (b) 3D-reconstructed CT images of the porcine ET phantom showing a posterolateral curvature until midpoint, followed by a curved anterior wall. The (c) height and (d) width of the axially sectioned porcine ET phantom gradually decreased from the nasopharyngeal ostium to the isthmus.
