How much electricity does a CT scan use per patient?

A typical CT scan uses approximately 5 to 10 kilowatt-hours (kWh) of electricity per patient. The exact amount can vary based on factors such as the type of CT machine, the specific scan being performed, and the duration of the scan. This energy consumption is relatively low compared to other medical imaging technologies, but it's still significant when considering the total number of scans performed in healthcare facilities.
