dual-energy imaging

dual-energy imaging

[dyo̅o̅′əl]
a radiographic imaging technique in which two radiographs using two different kilovoltages are taken of the same target area. Because the radiographic image of soft tissue and bone varies with the kilovoltage, one radiograph isolates bone contrast and the other isolates soft tissue contrast. The combined x-ray films can facilitate a more precise identification of an abnormality, such as a lung nodule calcification.

Different technical approaches have been developed by manufacturers to obtain dual-energy imaging datasets: dual-source CT scanners, equipped with two X-ray tubes operating at low and high voltages, respectively; (8) single- source rapid kV-switching CT scanners, in which a single X-ray tube alternates high and low tube potentials; (9) and single-source CT scanners equipped with dual-layer scintillating detectors, where the inner detector layer collects the low-energy data while the high-energy data are collected by the outer layer.
