A pulmonary airway tree segmentation method for tracheal wall gap closure under spheroid region constraints |
| abstract |
The invention discloses a pulmonary airway tree segmentation method for sealing a gap in a tracheal wall under the constraint of a spheroid region, and belongs to the field of image processing. Aiming at the leakage problem caused by low-brightness tracheal wall gaps in pulmonary airway tree segmentation, the present invention proposes a pulmonary airway tree segmentation method for tracheal wall gap sealing under the constraint of a spheroid region, including the following steps: (1) A sphere-like region constraint model was established; (2) segmentation and parameter adaptive adjustment in the region; (3) tracheal wall gap closure. The constraint of the sphere-like region on segmentation reduces the difficulty of leak detection, and it is easy to adjust each parameter adaptively in the constraint region. The sphere-like region constraint creates conditions for the sealing of tracheal wall gaps; the tracheal wall gap sealing can effectively locate and block The tiny low-brightness tracheal wall gap creates a good segmentation environment for the extraction of the 3D structure of the pulmonary airway tree. |
