Medical imaging is crucial for radiotherapy, guiding treatment precision and target definition. Advanced digital imaging techniques enhance accuracy and improve patient care in radiation oncology.

Area of Science:

  • Medical physics
  • Radiotherapy
  • Medical imaging

Background:

  • Radiotherapy relies heavily on medical imaging for disease extent and spatial relationships.
  • Traditional patient positioning methods are insufficient for high-accuracy radiotherapy.

Purpose of the Study:

  • To highlight the increasing role and impact of digital imaging in radiotherapy.
  • To discuss advancements in imaging for precise target definition and treatment delivery.

Main Methods:

  • Utilizing advanced imaging techniques such as CT scanning, MR-based dosimetry, image fusion, and 3D reconstruction.
  • Implementing on-line portal imaging for real-time verification and correction of target positioning.
  • Leveraging digital image processing, transmission, storage, and standards like DICOM and PACS.
