WebApr 28, 2024 · Dr. Leo Ding. Proton arc therapy is an advanced radiation therapy technique that consists of a continuous delivery of a proton beam as the gantry rotates around the patient. During this rotation, the beam energy and intensity are adjusted to confer higher conformality to the tumor, more efficient delivery and increased plan robustness. Web2 days ago · Introduction: Radiotherapy plays an important role in the treatment of oropharyngeal cancer (OPC) patients. However, radiotherapy is also associated with a wide spectrum of radiation-induced toxicities which reduces quality of life. 1 Technological advances, such as intensity modulated radiotherapy (IMRT), volumetric modulated arc …
