The Non-Invasive Measurement of Geometry of Human Ossicles

Abstract:

This study is to reconstruct the 3D model of ossicles by the smoothing technique that fitted to the human ossicles. The length of the geometry of the model was then measured. The image of human ossicles was obtained by the micro computed tomography scan. The 3D model of human ossicles was reconstructed by image processing, and then the length of the geometry of the 3D model was measured. The 3D model of human ossicles was reconstructed by image processing and by surface smoothing technique in this study. The surface of the ossicles model was smoothed by Smoothsurface. The length of the short process of the incus was 1.8 mm. The length of the long process of the incus was 5.2 mm. Based on the results obtained by this study, there was almost no difference for the measurements of the lengths of the cadaver malleus and incus between by observation and by image processing. Therefore, the image processing method was convenient and reliable. By the 3D model of ossicles, the clinician could know the structure of middle ear and could diagnose the middle ear disease more exactly.
