Overview
Radiotherapy is a local treatment that uses ionizing radiation of various energies to irradiate tumors in order to control and destroy cancer cells. Precise localization in radiotherapy remains a key challenge: ensuring beams accurately target the tumor while minimizing dose to surrounding healthy tissue is essential. 艾瑞迈迪 has accumulated extensive research and application experience in radiotherapy localization, covering the full workflow from pre‑treatment planning to high‑precision intraoperative techniques, including detailed preoperative planning, precise brain segmentation, high‑efficiency instantaneous registration, advanced respiratory motion compensation strategies, and multi‑modal image fusion. These capabilities improve targeting accuracy and support clinical implementation of advanced radiotherapy techniques.

System modules

• 3D reconstruction
  • Patient surface 3D reconstruction
  • CT/MRI 3D reconstruction
• Pre‑treatment planning
  • Target delineation
  • Radiotherapy path planning
  • Dose planning

Technical advantages

• Sub‑millimeter instantaneous surface reconstruction and registration: 瑞瞳 series cameras perform 3D surface reconstruction and rapidly register point clouds to preoperative images.
• Intelligent assisted patient positioning: intraoperative patient surface models fused with preoperative CT enable high‑precision 6‑DoF couch auto‑positioning assistance.
• Real‑time treatment‑area monitoring: continuously monitor pose changes of the irradiated region to trigger beam pause and prevent unintended overexposure.
• Respiratory‑gated beam control: extract respiratory signals from surface deformation data and synchronize beam delivery to breathing phases.
