Scope for energy improvement for hospital imaging services in the USA

摘要: ObjectiveTo aid radiologists by measuring the carbon footprint of CT scans quantifying in-hospital and out-of-hospital energy use to assess public health impacts.MethodThe study followed a standard life cycle assessment protocol measure from scan then expanding all hospital electrical related usage. In addition, fuel used generate electricity manufacture consumables was measured. The conducted at two hospitals.ResultsThe entire for 24–34 kWh natural resource per scan. actual active patient that produces images is only about 1.6% this total energy. This large multiplier get previously undocumented environmental response direct radiology order idle periods, where machine on but no patients are being scanned 14–30-fold higher than t...
