X\u2010ray sensitometry was performed using mammography screens that were modified to accommodate a graded optical step tablet (screen sensitometry). Finally, a means for performing intensity\u2010scale x\u2010ray sensitometry was configured (inverse\u2010square sensitometry). Clinical mammography x\u2010ray exposure conditions were used and film processing quality was closely monitored during the study. Statistical results for chi\u2010square probabilities on the resulting contrast curves yielded good agreement for most of the configurations investigated. Comparison of film gradient versus optical density curves showed good agreement for maximum contrast values and the corresponding optical density for maximum contrast for three of the four screen\u2013film combinations used when comparing light sensitometry to screen sensitometry. A similar comparison of light sensitometers to inverse\u2010square sensitometry showed good agreement for maximum contrast, but less agreement for the corresponding optical density of maximum contrast. Based on these results, the authors concluded that commercially available sensitometers could be used to estimate clinical film performance for the screen\u2013film systems tested. In particular they can be used to determine the range of optical densities that provide optimal film contrast.<\/jats:p>","DOI":"10.1118\/1.598996","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T14:01:44Z","timestamp":1027692104000},"page":"854-860","source":"Crossref","is-referenced-by-count":7,"title":["Using light sensitometry to evaluate mammography film performance"],"prefix":"10.1002","volume":"27","author":[{"given":"Michael S.","family":"West","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David C.","family":"Spelic","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2000,5,5]]},"reference":[{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.190.2.8284372"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(05)81741-6"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1259\/bjr.71.849.10195010"},{"key":"e_1_2_1_5_1","unstructured":"K.
