Sustainable Imaging in Africa: Powering Radiology with Resilient Technology
The Power Challenge in African Radiology
Sustainable radiology in Africa is becoming increasingly important as healthcare providers search for ways to reduce costs, lower energy consumption, and build resilient imaging services. By adopting more eco-friendly radiology solutions, health systems can improve patient care while reducing environmental impact. This shift towards sustainable radiology is helping facilities deliver reliable imaging even in regions with infrastructure challenges.
When the grid fails mid-scan, not only is the procedure delayed, but sensitive electronics risk permanent damage. Clinics often rely on diesel generators, but these are costly, hard to maintain, and frequently fail to provide the surge power X-rays require. For example, a mobile X-ray outreach project in rural Kenya, part of an initiative by faculty from Indiana University and Moi University under the AMPATH consortium, faced constant power setbacks.
Every time the X-ray machine was activated, the sudden surge of electricity overwhelmed the truck’s generator, tripping the circuit breakers and shutting down the system. Clinicians had to restart both the generator and imaging equipment after nearly every scan, which delayed care and highlighted how inadequate power infrastructure can severely undermine radiology services in resource-limited settings (RSNA, 2015).
Key Facts:
– Nearly 50% of Sub-Saharan hospitals lack reliable electricity.
– Generators may trip during X-ray use, making imaging unreliable.
Sustainable Radiology in Africa: Solar and Battery Power
Solar power is emerging as a game-changer. With abundant sunshine, clinics can pair panels with battery storage, ensuring uninterrupted imaging.
For example, St. Luke’s Hospital in Wolisso, Ethiopia, which serves around half a million people, has benefited from a hybrid solar-battery installation by Enel Green Power in partnership with the NGO Doctors with Africa CUAMM. They installed a hybrid solar-battery system, delivering a stable 320 kWh supply, which dramatically cuts outages. Smaller clinics use solar suitcase kits, portable panels, and batteries to power X-ray or ultrasound machines. The African Union has encouraged the use of off-grid renewable energy sources for clinics, especially in areas where power outages occur up to 50% of the time. (Enel Green Power, 2019)

Success Stories:
– Ethiopia’s St. Luke’s Hospital: Hybrid solar-battery system cut outages significantly.
– Kenya & Malawi clinics: Solar-powered mobile X-rays now run reliably in rural villages.
Energy-Efficient Imaging Technology
Modernising equipment is just as necessary as fixing power challenges, especially for facilities aiming to advance sustainable radiology in Africa. Old film-based X-rays consume more energy and require chemicals and water for film processing. In contrast, DRGEM’s digital radiography systems eliminate film development, lowering both power demand and environmental waste.
Energy efficiency is built into DRGEM’s design. For instance, the GXR Series uses a high-frequency generator that minimises kV ripple and pulls only the necessary current. Many machines also feature power-save modes, reducing standby consumption in smaller clinics and supporting broader efforts toward sustainable radiology in Africa.
Product Highlights:
– GXR Series: High-frequency generator reduces power strain.
– Topaz: Battery-powered mobile X-ray for off-grid clinics.
Sustainable power solutions are transforming radiology across Africa. Combining solar energy with a resilient design and energy-efficient DRGEM systems can enable clinics to provide reliable imaging even in unstable environments.
FAQs
