| 成果简介 | NOVELTY - Invention refers to medicine, namely to angiosurgery, and can be used to assess correctness of flow-directing stent placement. Intravascular optical coherence tomography of the investigated blood vessel is performed. Stent frame is identified. Structural images for the moment of systole are quantitatively compared with the structural images for the moment of diastole. Absolute displacements of structures and sizes of deformable areas are determined from control points. Obtained cartogram is used to assess the results of identifying fragments of the stent frame by comparing the calculated values with the values of the material of the stent implanted into the analysed vessel, results of determining the boundaries of the lumen of the blood vessel are compared with the average values of the optical properties of the structures of the analysed blood vessel, and when the stent fragments are pressed into the blood vessel wall by a value greater than 0.2 mm, the flow-directing stent installation is considered to be incorrect. USE - Medicine. ADVANTAGE - Method enables spatial positioning and correct deployment of the flow-directing stent by taking into account differences in optical and mechanical properties between the analysed biological tissues and the stent material by analysing structural images for the moment of systole with structural images for the moment of diastole and taking into account the deforming force of the pulse wave. 1 cl |
