Diagnostic imaging HESI

Diagnostic imaging HESI test prep Questions and answers If an image of optimal radiographic density was acquired using a traditional film-screen system at 16 milliampere-seconds (mAs) and a source-image distance (SID) of 100 cm, what mAs is required to produce the same density at a new distance of 50 cm? A. 32 mAs. B. 4 mAs. C. 8 mAs. D. 2 mAs. B Which procedural error is most likely to cause a long bone to appear foreshortened on a radiographic image? A. The x-ray beam is not perp...
