Area of Science:

  • Medical Imaging
  • Radiology
  • Computer-Aided Diagnosis

Background:

  • Accurate lung field segmentation in Computed Tomography (CT) scans is crucial for diagnosing and treating pulmonary diseases.
  • Existing automatic segmentation methods for lung fields in CT scans are continuously being improved.

Purpose of the Study:

  • To propose a novel, effective automatic segmentation method for lung fields in thoracic CT scans.
  • To enhance the accuracy of lung segmentation by incorporating anatomical information.

Main Methods:

  • The proposed method utilizes morphological closing operations and thresholding for segmenting normal lung fields.
  • Anatomical information, including lobar fissures, inter-lung junctions, and vascular/bronchial structures, guides the segmentation process.

Main Results:

  • The novel method successfully segmented lung fields in thoracic CT scan datasets.
  • The incorporation of anatomical details improved the precision of the lung field segmentation.

Conclusions:

  • The developed segmentation method is effective for lung fields in CT scans.
  • This approach offers a valuable tool for the analysis and diagnosis of pulmonary conditions.
