Motion Artifact Reduction in Dual Energy Radiography

01 July 2021

The article considers measures for reducing motion artifacts occurring on separate images of tissues when performing dual energy radiography.

Dual energy radiography is a relatively simple but powerful tool of X-ray diagnosis. It increases the diagnostic value of radiographic examination by generating separate images of bony and soft tissues. In two shot dual energy radiography, separate images of tissues are constructed from the two initial images obtained at different anode voltages. The process of acquiring the initial images is extended in time and includes a pause between exposures. The result is that the separate tissue selective images can carry motion artifacts, reducing their diagnostic value. In this study the ways of reducing motion artifacts are considered.
