Mammography in the '80sBurton J. Conway, MS, Rockville, MD • John L. McGrohan, MS • Fred C. Rueter, DSc • Orhan H. Suleiman, PhDA national survey of 232 mammographic units was conducted in 1985 as a part of the Nationwide Evaluation of X-Ray Trends (NEXT) program. Another national survey was conducted in 1988 on 226 mammographic units. These surveys clarified trends in potential dose for film-screen and xerox systems, improvements in image scores, and trends in mammographic equipment (including the effects of grid usage on dose and image score); they also provided data regarding the phantoms used and how these relate to the phantom used in the American College of Radiology Accreditation Program.11:03 AM462. Daily Mammography Quality Control with Test Object, Sensitometer Strip, and Exposure measurements: Are They NecessaryCarolyn Kimme-Smith, PhD, Los Angeles, CA • Christopher H. Cagnon, BA, CRT • Lawrence W. Bassett, MD • Richard H. Gold, MDDaily sensitometry strips for processor quality control were matched with a physicist's measurements of MR/mAs and radiation exposure of a CIRS phantom. Technologists' evaluations of daily films of three CIRS phantoms imaged on three mammographic units were also correlated with the sensitometry strips and physicist's results. The phantom images were evaluated for consistent density, resolution targets, and contrast targets. Test-object imaging was the least responsive to equipment malfunction. Daily measurements by the physicist were found to be unnecessary, but such measurements were continued on a weekly basis. Usefulness of sensitometer-strip results depends on automation and statistical error analysis, because daily variations may be within normal processor variability.Article HistoryPublished in print: Feb 1990 FiguresReferencesRelatedDetailsRecommended Articles RSNA Education Exhibits RSNA Case Collection Vol. 174, No. 2 Metrics Altmetric Score PDF download
