Abstract:
This paper comprehensively explores the application value and current development status of rotating gantries in radiotherapy. First, it explains the concept of rotating gantries and their significant advantages in clinical treatment, including enhancing patient comfort, optimizing irradiation angles, and improving treatment stability. Next, an in-depth analysis of the global development of particle therapy rotating gantries is provided, covering the distribution and construction costs of proton and carbon ion therapy centers, as well as the practical applications and challenges of rotating gantries in different particle therapies. Additionally, the working principles of rotating gantries are described in detail, particularly the effects of rotational speed and magnetic rigidity on equipment size and performance. Furthermore, the factors that need to be comprehensively considered in the design of rotating gantries are systematically reviewed. Finally, through a comparative analysis of multiple clinical studies, it fully confirms the remarkable clinical advantages of rotating gantry systems over traditional fixed-beam systems in various cancer treatment scenarios. It also provides a reasonable outlook on their future development, pointing out that as technology advances and costs decrease, rotating gantries are expected to be widely adopted in medical institutions, bringing positive changes in cancer treatment.
