    This study introduces a novel three-dimensional (3D) treatment planning system for radiation therapy. The system enhances visualization and allows for precise shaping of radiation fields, reducing normal tissue exposure.

    Area of Science:

    • Medical Physics
    • Radiation Oncology
    • Radiotherapy Planning

    Background:

    • Traditional two-dimensional (2D) treatment planning can lead to suboptimal radiation delivery.
    • Accurate visualization of tumor and organ geometry is crucial for effective radiotherapy.
    • Existing planning systems may not fully capture the complex spatial relationships in 3D.

    Purpose of the Study:

    • To present a novel three-dimensional treatment planning system.
    • To demonstrate the system's capability in visualizing spatial relationships between radiation beams, tumors, and organs.
    • To highlight the potential for improved treatment field design and reduced normal tissue irradiation.

    Main Methods:

    • Development of a three-dimensional treatment planning system at Rhode Island Hospital.

  • Implementation of interactive visualization tools, including rotation and scaling.
  • Utilizing the system to design shaped treatment fields from the perspective of the radiation beam.

    • Main Results:

    • The system provides clear visualization of the spatial interrelationships of critical structures.
    • Interactive features allow for better comprehension of tumor and organ extent.
    • The system facilitates the design of treatment fields tailored to the three-dimensional nature of the disease.

    Conclusions:

    • The developed 3D treatment planning system offers superior visualization for radiotherapy.
    • It enables the design of more conformal radiation fields compared to 2D methods.
    • This approach has the potential to significantly reduce the volume of normal tissue irradiated, improving patient outcomes.
