Grid-like contrast enhancement for bedside chest radiographs acquired without anti-scatter grid

Bernd Menser, PhD, X-Ray Scientist Bedside chest radiographs can be acquired with or without an anti-scatter grid. Using a grid may improve image contrast, although it is frequently avoided in clinical practice, due to dose considerations, beam alignment difficulties, and a more complicated workflow[2]. Also, structures appearing from the (usually stationary) grid may interfere with diagnostic details[4]. Unfortunately, the image quality of non-grid chest images is frequently compromised by a large amount of scattered radiation, causing a loss of image contrast. The images may appear flat, and even with manually adapted viewing settings for digital chest radiographs, image representation may be poor.
