An X-ray and γ-ray combination strategy to exploit steep dose gradients for improved prostate cancer radiotherapy: A dosimetric comparison of Taichi Pro and Halcyon.

Key Points

• The study aims to compare the effectiveness of the Taichi Pro dual-modality system and Halcyon in escalating target doses while preserving adjacent organs.
• Comparison of the dosimetric capabilities of Taichi Pro and Halcyon systems.
• Utilization of steep dose gradients characteristic of the RGS.
• Evaluation of target dose escalation and organ sparing.
• Taichi Pro achieved higher target dose escalation than Halcyon.
• Improved sparing of adjacent organs at risk was noted with Taichi Pro.
• Potential enhancement of patient treatment outcomes and quality of life was suggested.
