Sentence examples for background was measured using from inspiring English sources
The number of photo-stimulated luminescence events per square millimeter (PSL/mm2, mean ± SD) corrected for background was measured using vendor-specific software (BAS-Reader) by drawing individual regions of interest (ROIs) for the aortic wall and psoas muscle, facilitated by comparison with block face photos for each section.
