Background:

Accurate segmentation of anatomical structures in computed tomography (CT) scans is crucial for medical diagnosis.
Identifying region-specific voxels presents a significant challenge in automated segmentation processes.

Purpose of the Study:

To introduce and evaluate the application of granular computing for detecting anatomical structures in abdominal CT scans.
To develop an automatic model-based approach utilizing information granules for organ-specific voxel identification.

Main Methods:

Implementation of granular computing principles to identify information granules representing specific organs.
Development of a three-parameter granule combining voxel interval and density distribution.
Application of the developed granule for identifying voxels of the liver, spleen, and kidneys in abdominal CT data.

Main Results:

Demonstrated the effectiveness of information granules in identifying organ-specific voxels.
Achieved high specificity rates: 90-99% for the liver and spleen.
Attained over 85% specificity for kidney voxel detection.

Conclusions:

Granular computing offers a viable and effective method for enhancing the accuracy of anatomical structure detection in CT imaging.
The proposed three-parameter granule model shows significant promise for automated organ segmentation, particularly for the liver, spleen, and kidneys.
