Improving radiation therapy efficacy involves precise dose distribution to minimize treatment volume. This enhances tumor control probability and reduces side effects by sparing healthy tissues from radiation exposure.

Area of Science:

  • Radiation Oncology
  • Medical Physics
  • Cancer Treatment

Background:

  • Improving radiation therapy efficacy relies on optimizing dose distribution.
  • Reducing the treatment volume enhances tumor control and minimizes radiation-induced morbidity.
  • Advanced techniques are crucial for precise targeting and dose delivery.

Purpose of the Study:

  • To explore strategies for reducing radiation therapy treatment volumes.
  • To compare treatment volumes in surgical versus radiation therapy for specific cancers.
  • To present methods for enhanced dose distribution and treatment monitoring.

Main Methods:

  • Utilizing 3D graphic reconstruction for tumor and normal structure visualization.
  • Incorporating uncertainty bands around isodose contours in treatment planning.
