A New Approach to the Improvement of Energy Efficiency in Radiology Practices
Hans-Martin Klein
Abstract
PURPOSE: We examined ways to improve energy efficiency in radiology by using regenerative and energy-friendly technology in the construction and operation of two radiological facilities. METHOD: In the years 2009 to 2010 an energy-optimized medical center with different clinical disciplines and a radiology practice was built. We used regenerative energy production (photovoltaic system, 29.92 kWp). A heat exchanger was also used to regain thermal energy to support heating of the building, thereby reducing cooling energy consumption. The practice operates a 1.5 T MRI machine and a computed tomography scanner. Derived from our experiences, an open MRI practice was built nearby in 2019. The building was constructed using an energy-saving technique. A photovoltaic system with a 10 kWh lithium-ion battery was installed. The practice operates a 0.35 T open MRI machine. RESULTS: /year. CONCLUSION: footprint in radiology practices. KEY POINTS: · Radiology, in particular MRI, has high energy consumption.. · A heat exchanger can regain thermal energy from MRI machines to support room heating.. · Low-field MRI with permanent magnets consumes far less energy.. · Energy optimization results in less CO2 production and lower operation costs..
