DEVELOPMENT OF AN ALGORITHM FOR PROCESSING THE RESULTS OF MULTISPIRAL COMPUTED TOMOGRAPHY OF THE ORBIT IN AUTOMATIC MODE FOR CONSTRUCTING A THREE-DIMENSIONAL MODEL OF THE ORBIT AND ORBITAL IMPLANT

The aim of the work is to develop a technology for constructing a 3D model of the lower and medial bones of the facial skull while preserving complete information about their geometry based on the results of multispiral computed tomography (DICOM files). Material and methods: During the study, DICOM images of patients were analyzed. Results. An algorithm for preparing DICOM images for constructing a three-dimensional model of the facial bones has been developed. The DICOM image processing algorithm reduced the level of data loss on the thin bones of the orbit when constructing a three-dimensional model of the facial bones from 22–31% to 3–5%. The developed software automatically changes the color of the pixels of the thin orbital bones from gray to white. The thin orbital bones were expanded by one pixel using the DICOM image processing algorithm. Conclusions. The analysis of the image processing results by the developed software was carried out using the 3D Slicer software. As a result of the development of this software, it was possible to obtain a full-size 3D model of the orbit with a bone defect and a 3D model of an individual orbital implant.
