    Area of Science:

    • Medical Imaging
    • Surgical Navigation
    • Computer-Assisted Surgery

    Background:

    • Image registration is crucial for computer-assisted surgery.
    • Current laparoscopic navigation systems lack deformation compensation.
    • Accurate real-time anatomical information is vital for deep-seated procedures.

    Purpose of the Study:

    • To develop a deformable image registration algorithm for surgical navigation.
    • To compensate for continuous deformations in the operating environment.
    • To provide surgeons with updated, accurate navigational information.

    Main Methods:

    • Extended rigid registration to a shape-preserving deformable registration.
    • Incorporated user interaction and iterative mesh editing.
    • Preserved local anatomical details during registration.

    Main Results:

    • Successfully tested the deformable registration workflow on phantom and animal trial datasets.
    • Expert feedback indicated satisfactory qualitative outcomes.
    • Achieved efficient execution performance.

    Conclusions:

    • The proposed deformable registration method enhances surgical navigation accuracy.
    • Its ease of implementation makes it suitable for augmented reality assisted surgeries.
    • The algorithm shows promise for pre-clinical and clinical adoption.
