    Area of Science:

    • Medical Imaging
    • Computer Vision
    • Computational Biology

    Background:

    • Accurate organ segmentation in computed tomography (CT) images is crucial for medical diagnosis and treatment planning.
    • Existing methods may face challenges in precisely delineating multiple organs within abdominal scans.

    Purpose of the Study:

    • To develop and evaluate an advanced organ segmentation technique for abdominal CT images.
    • To improve the accuracy and efficiency of segmenting key abdominal organs: liver, kidney, and spleen.

    Main Methods:

    • Proposed the organ location determination and contour sparse representation (OLD-CSR) method.
    • Utilized an extreme learning machine classifier for segmentation.
    • Implemented a coarse-to-fine segmentation strategy involving location determination and contour refinement using sparse optimization.

    Main Results:

    • The OLD-CSR method demonstrated performance advantages over existing related work.
    • The approach effectively segments multiple organs including the liver, kidney, and spleen.
    • Experiments on 153 CT images validated the proposed method's efficacy.

    Conclusions:

    • The OLD-CSR method offers a robust and accurate solution for multiorgan segmentation in abdominal CT.
    • This technique holds potential for enhancing clinical applications in medical imaging analysis.
