    Spatially Fractionated Radiation Therapy (SFRT) enhances tumor control while preserving normal tissues, especially for bulky or radio-resistant tumors.

  • 2

    Stereotactic Centralized Ablative Radiation Therapy (SCART) optimizes SFRT by concentrating high-dose regions within the tumor's core.

  • 3

    A new algorithm based on polar-coordinated calculations significantly improves SCART Treatment Volume (STV) generation, reducing time by 90%.

  • 4

    The algorithm enhances STV volume by 15% and improves conformality compared to manual contouring methods.

  • 5

    SCART demonstrates high local control rates, with 95% of tumors showing partial or complete responses in initial clinical studies.
