    A novel computerized tomography algorithm enhances image reconstruction using four X-ray scans. This iterative method corrects image data for clearer transverse axial imaging.

    Area of Science:

    • Medical Imaging
    • Computerized Tomography
    • Image Reconstruction

    Background:

    • Computerized tomography (CT) is crucial for medical diagnostics.
    • Accurate image reconstruction is vital for diagnostic efficacy.
    • Existing CT algorithms may face limitations in certain applications.

    Purpose of the Study:

    • To introduce a modified orthogonal tangent correction algorithm for CT.
    • To improve the accuracy and quality of transverse axial image reconstruction.
    • To evaluate the algorithm's performance on phantom and real-world data.

    Main Methods:

    • Development of a modified orthogonal tangent correction algorithm.
    • Utilizing four X-ray scans spaced 45 degrees apart for data acquisition.
