Algorithm of processing microspiral CT-scan results for constructing a three-dimensional model of orbit thin bones

Abstract

We developed the algorithm for preparation of DICOM images for the construction of a three-dimensional model of the bones of the facial skull. The DICOM image-processing algorithm reduced the data loss level about the thin bones of the orbit during building a three-dimensional model of the bones of the facial skull from 22–31% to 3–5%. The developed software automatically changes the color of the pixels of the thin bones of the orbit from gray to white. Thin bones of the orbit were expanded over one pixel using the DICOM image-processing algorithm. The analysis of the image processing results by the developed software was carried out using 3D Slicer software.

În lucrare este analizat algoritmul de pregătire a imaginilor DICOM pentru construirea unui model tridimensional al oaselor craniului facial. Algoritmul de procesare a imaginii DICOM a redus nivelul de pierdere a datelor despre oasele subțiri ale orbitei în timpul construirii unui model tridimensional al oaselor craniului facial de la 22-31% la 3-5%. Software-ul dezvoltat modifică automat culoarea pixelilor oaselor subțiri ale orbitei de la gri la alb. Oasele subțiri ale orbitei au fost extinse peste un pixel utilizând algoritmul de procesare a imaginilor DICOM. Analiza rezultatelor procesării imaginilor prin software-ul dezvoltat a fost realizat folosind software-ul 3D Slicer.
