Energy consumption of ultrasound devices during routine applications and opportunities to save energy and costs
摘要
To determine the real energy consumption, including the idle and off-mode status of ultrasound devices and their multiparametric modes during daily examinations.
Material and methodsIn this study, the electrical power consumption from 9 ultrasound devices and 18 probes used in routine medical practice was measured for a full 24 h over a week. The equipment was located in the neurology and cardiology departments of a large hospital, as well as in a radiology medical practice. The devices were manufactured by different companies and varied in age.
ResultsShort-term measurements recorded the electrical power consumption during patient scans, revealing real power values for the applied modalities, which ranged between a mean of 182.5 W and 415.5 W, depending on the device and application field. Long-term measurements, reflecting the typical working days of these departments, showed total annual electrical power consumption ranging from 344.6 kWh to 1122.6 kWh. Energy-saving possibilities are discussed, highlighting that reducing idle-mode durations can significantly lower electrical costs by saving energy of 3–16%.
ConclusionThis study is the first to document in detail the power consumption of different ultrasound devices and modalities, including idle and off-mode statuses, during routine use.
