A new web-based 3D simulator helps prevent collisions during external beam radiation therapy. It uses accurate 3D models of linear accelerators and patient scans for early detection, ensuring safer cancer treatment delivery.

Area of Science:

  • Medical Physics
  • Radiation Oncology
  • Computer Simulation

Background:

  • External beam radiation therapy (EBRT) requires precise radiation delivery for cancer treatment.
  • Linear accelerators (LINACs) in EBRT have complex moving hardware, posing collision risks with patients or components.
  • Accurate 3D modeling is crucial for simulating these complex geometries.

Purpose of the Study:

  • To develop a web-based 3D visual simulator for early detection of potential collisions in radiation therapy.
  • To enhance the safety and accuracy of external beam radiation therapy by identifying and mitigating collision risks.
  • To provide a tool for visualizing the complex interplay between LINAC hardware and patient anatomy.

Main Methods:

  • Development of a web-based 3D simulator.
