Article Title: Variations in cochlear duct shape revealed on clinical CT images with an automatic tracing method

doi: 10.1038/s41598-017-16126-6

Figure Lengend Snippet: Illustration of the automatic tracing method. ( a ) MPR slice of a pre-operative cochlear CT scan. ( b ) Midmodiolar cross-section of the cochlea at the angle indicated by the yellow line in ( a ). ( c ) Interpolated voxel intensity along the yellow lines in ( a ) and ( b ); the top plot shows voxel intensities along the top yellow line in figure ( b ), while the bottom plot corresponds to the bottom yellow line shown in ( b ). The purple, light blue and green circles indicate the locations determined for the outer wall, inner wall, and floor of the scala tympani, respectively. The purple and light blue curves in the MPR of figure ( a ) are projections of the automatically traced outer and inner walls. The Black dots in figure ( c ) indicate minima and maxima.

Article Snippet: Figure shows the corresponding midmodiolar cross-section at 25°, which is obtained by first calculating image profiles using the ‘improfile’ function in MATLAB, which interpolates the voxel intensities along the radial lines in each MPR slice (the lines were extended across the entire MPR slice and thus also included the opposite side of the modiolar axis, i.e. the radial line at 205°).

Figure Lengend Snippet: (a) An ultrasound image of a cross-section of the inflated CS vessel, with two line segments D1 and D2 for measuring diameters and three line segments T1, T2 and T3 for thickness measurements; (b) thickness measurements using the FWHM method (to obtain Tpixel, or the thickness in pixels, of the width of the half amplitude of the peak); (c) diameter measurements (distance between the two crosses, in pixels), both processed by the Matlab “improfile” function.
