Comparison of Energy Consumption Between Single Energy O-Gantry and Dual Energy C-Arm Linear Accelerator

Environmental pollution in the form of high energy usage and greenhouse gas emissions (GHG) is a major contributor to climate change, as the continued modernization of processes across industries is associated with the introduction of newer technologies that consume more energy. Prior research has identified the transportation and the health care sectors to be major sources of environmental pollution.1,2 Some estimates attribute about 10% of the carbon footprint of health care to clinical radiology and radiation therapy (RT).
