Abstract

One of the key factors for sustainable decision making is the ability to draw comparisons of environmental impacts between different alternatives. These decisions are the subject of many articles in most sectors of the economy. In one area of the service sector, healthcare, there is a lack of information to make the similar decisions. The significant growth in the healthcare industry implies a more detailed collection and examination of the environmental information so that decisions regarding those specific impacts may ensue. This research focuses on imaging in healthcare. Since the number of CT scans has significantly increased in the U.S. in recent decade, there are efforts to investigate alternative imaging tools. An available option is the latest technologies in digital radiography (DR): dual-energy imaging, digital tomosynthesis, and computer-aided detection. In this paper, the energy consumed by the DR technologies is compared to the energy consumed by CT. The overall goal is to determine areas for energy savings. The results reveal the delivery of a CT scan consumes much greater amount of direct energy in contrast to DR systems. In addition, the amount of embodied energy in medical consumables is also higher in the delivery of a CT.
