Using geometric primitives to determine densitometric data in analyzing the bone tissue structure at transpedicular fixation

The problem of modern navigation methods using segmentation lies in transformation of data on the bone tissue structure into a single object representing a solid three-dimensional model. This problem could significantly influence the quality of the implant position. Analysis of raster images and studying the Hounsfield units at the implant positioning would make it possible to selecting trajectories for their input. The paper proposes a method for determining the patient densitometric data in computer tomography to analyze the bone tissue in transpedicular fixation. The proposed method is based on obtaining the Hounsfield units of the patient’s vertebral tissue using geometric primitives such as the lines. This method includes a set of actions for working with voxels in the computer tomography DICOM images. The method is illustrated with an example using the patient data. The example includes a set of graphs describing the vertebral pedicle structure along the selected cylinder.
