Dual Energy
Overview
Dual Energy (DE) is an optional imaging technique in which a low-kVp image and a high-kVp image are
acquired in rapid succession. The acquired images are processed to create a soft-tissue image and a
bone image, which are provided in addition to the standard (high-kVp for chest DE and low-kVp for abdo-
men) image.
Note:
Dual Energy is only possible with full digital exams, that is, only the wallstand and table receptors.
Dual Energy cannot be performed on a cassette exam.
Dual Energy acquisitions are currently enabled only for Chest and Abdomen AP and PA anatomical views.
Dual Energy has significant potential for improving the conspicuity of chest pathology by removing the
bone structures and for improving specificity by providing calcification information in the bone image.
