Establishing a quality control protocol for dual-energy based contrast-enhanced digital mammography

This study explores candidate metrics for use in a vendor-neutral Quality Control (QC) protocol for dual energy based (‘spectral’) contrast-enhanced digital mammography (DE-CEDM). The physical metrics were chosen for their anticipated link with clinical image quality. An extra criterion was that limiting values can be applied to these metrics. The following DE-CEDM characteristics were tested: (1) signal produced by test object inserts versus...
