    Area of Science:

    • Medical Imaging
    • Nuclear Medicine
    • Image Processing

    Background:

    • Accurate patient positioning is crucial for reproducible scintigram acquisition.
    • Existing methods may struggle with arbitrary patient positions, affecting diagnostic quality.
    • Image registration is essential for comparing or combining scintigraphic data.

    Purpose of the Study:

    • To introduce a new method for aligning scintigrams regardless of patient position.
    • To enhance the accuracy and reliability of scintigraphic image analysis.
    • To facilitate complex imaging studies of organs like the lungs and liver.

    Main Methods:

    • Utilizing two anatomical reference points for pre-examination coincidence.
    • Employing rotation and translation to align one scintigram relative to another.
    • Implementing the method on a specialized data processing system (MDS) using FORTRAN-4.

    Main Results:

    • Successful alignment of scintigrams acquired from patients in arbitrary positions.
    • Demonstrated applicability to complex imaging scenarios involving the lungs and liver.
    • The method provides a robust solution for image registration in nuclear medicine.

    Conclusions:

    • The proposed method offers a significant advancement in scintigram alignment.
    • It enhances the diagnostic utility of nuclear medicine imaging, particularly for challenging patient positions.
    • This technique is valuable for detailed examinations of thoracic and abdominal organs.
