It needs a morphological verification for diagnosis approving.Histological specimens can be taken during performing open lung biopsy, video-assisted thoracic surgery (VTS), and transbronchial lung biopsy (TBLB). VTS and TBLB are less invasive methods, allowing to take biopsy specimens. Nevertheless TBLB – is a blind method, and efficiency of VTS depends on optimal thoracoports placement.Aims: Increase the capabilities of such a methods of the biopsy material gaining.Methods and Materials: We create an algorithm and computer program, allowing us in 3D-modelling format to highlight organs of thoracic cavity and foci of lesions. The input data for such a system is a standard DICOM-packs of CT scans of rib cage. For voxel data visualization we used a marching cubes algorithm. We were able by means of our computer program to make a 3d-modell of bone skeleton, bronchial tree, lung parenchyma and highlighted а foci of lesions, the size of lesions was from 1 mm to 30 mm. And lesions were placed as isolated so extrapleuraly and extravascularly.Results: Developed technology allowed us to define the arrangement of DLIL in 3D-format and optimal access place and trajectory length of biopsy forceps during TBLB performing, and also calculate points of thoracoports placement for performing VTS. Created technology permit us to increase the informativity of TBLB in 1,6 times, sufficiently increase opportunities and reduce the length of VTS because of better conditions for manipulation on chosen for resection parts of lungs.
