    Area of Science:

    • Medical Imaging
    • Computer-Aided Diagnosis
    • Neuroscience

    Background:

    • Traumatic brain injury (TBI) presents a significant global health challenge, leading to substantial disability and mortality.
    • Efficient and accurate diagnosis of TBI is critical for effective patient management and improved outcomes.
    • Current diagnostic methods can be time-consuming, and computer-aided analysis offers potential for enhanced speed and accuracy.

    Purpose of the Study:

    • To develop an automated system for segmenting hematoma regions in CT images for TBI diagnosis.
    • To improve the efficiency and accuracy of TBI diagnosis through advanced imaging analysis.
    • To provide a tool for real-time clinical guidance and quality assurance in TBI assessment.

    Main Methods:

    • The proposed system incorporates image preprocessing steps, including denoising and enhancement, to address challenges like image noise and artifacts.
    • A Gaussian mixture model (GMM) is developed and applied for the segmentation of hematoma regions.
    • The automated segmentation results are quantitatively compared against ground truth data meticulously generated by medical specialists.

    Main Results:

    • The automated system demonstrates promising performance in accurately identifying and segmenting hematoma regions from CT images.
    • Image enhancement techniques effectively mitigated noise and artifacts, improving the quality of input data for segmentation.
    • The GMM-based segmentation achieved reliable results, closely aligning with expert-defined ground truth.

    Conclusions:

    • The developed automated system shows potential for accelerating and improving the accuracy of TBI diagnosis via CT image analysis.
    • This approach can aid clinicians in real-time diagnosis, potentially reducing mortality and long-term complications associated with TBI.
    • Further development and validation could integrate this system into clinical workflows for enhanced TBI patient care.
