Sustainability in Computed TomographyImaging a greener tomorrow
The healthcare sector is currently the fifth largest contributor to global greenhouse gas emissions1. At Siemens Healthineers, we are committed to reducing our climate footprint to a minimum. We strive to achieve net-zero emissions by 2050 – and to support you in reaching your own goals with sustainable Computed Tomography (CT). Our CT innovations are designed to lower energy consumption, conserve resources, and help address global healthcare challenges.
Sustainable power consumption
Designed with sustainability and efficiency in mind, our latest CT scanners consume significantly less power compared to previous generations. Discover how sustainable CT technology can help you save energy with ease while supporting your environmental goals.
Sustainable use of resources
Every stage of a CT system’s lifecycle influences its environmental footprint. To help preserve natural resources, we prioritize reusability and recyclability across our systems and components. Discover how we advance sustainable CT imaging – from design to end of life.

How Dual Source CT technology becomes more accessible
Power consumption, site preparation, operational efficiency: Many aspects have an impact on a CT system’s total cost of ownership (TCO). Find out how our state-of-the art system design helps significantly decrease the annual costs of our Dual Source system SOMATOM Pro.Pulse, even when compared to a conventional single source system.
Saving energy in radiology
Radiology equipment is a major energy consumer, but even simple changes can deliver significant energy savings. Discover practical strategies and advanced technologies that help substantially reduce energy consumption – without compromising patient care.
FAQs
Sustainable CT systems are designed to keep energy consumption down, extend system lifecycles, conserve resources, and support responsible end-of-life management. Features such as energy saving modes, upgrades, and recyclable components help minimize environmental impact.
In many real-world settings, a significant share of CT energy use occurs while the system is idle and
not scanning. Energy consumption can be lowered by using power-saving features, switching the
system off during extended periods of inactivity, and upgrading to newer, more energy-efficient CT
technologies.
Not when it is done as part of a planned, vendor-recommended power management strategy. For shorter periods of inactivity, energy-saving or eco modes may be the most appropriate option, while complete shutdown can help save more energy during extended downtime, such as overnight. The right approach balances energy efficiency with operational readiness, helping reduce energy consumption without compromising workflow or patient care.
Depending on the system and usage patterns, the latest CT technologies can significantly cut daily energy consumption compared to previous generations, helping lower both environmental impact and operating costs.
Radiology departments can track sustainability progress using key metrics such as energy consumption (kWh), idle-time share, scans performed per kWh, and estimated CO2e based on local electricity grid factors. Monitoring these indicators over time helps identify opportunities for greater efficiency and quantify improvements. Operational measures, such as adherence to shut-down and power-management routines, can provide additional insight into the effectiveness of sustainability initiatives.
Upgrades help extend the useful life of existing systems, decreasing the need for premature replacement and conserving resources while maintaining access to the latest innovations and performance improvements.
Recyclability and refurbishment are important elements of a more sustainable approach to CT imaging. Designing systems and components for recyclability helps recover valuable materials at the end of a product’s life and supports a more circular use of resources. Refurbished components help conserve raw materials and avoid emissions associated with manufacturing new systems and parts – while continuing to meet high standards for quality, safety, and performance.
No. Sustainability initiatives are designed to complement clinical excellence. Energy-efficient technologies, upgrades, and lifecycle extension measures help lower the environmental impact while supporting high-quality patient care.
Sustainability in CT imaging is considered throughout the entire lifecycle – from design and manufacturing to operation, upgrades, servicing, refurbishment, and end-of-life management – to help reduce environmental impact and conserve resources.
