Group 2 images were acquired with a lower kVp (100 vs 125) and shorter source\u2010to\u2010image distance (127\u00a0cm vs 183\u00a0cm) and were expected to have lower quality than Group 1 images. Group 3 images were expected to have degraded contrast vs Group 1 images. Images were anonymized and securely transferred to the Duke University Clinical Imaging Physics Group for analysis using software described and validated previously. Individual image quality was reported in terms of lung gray level, lung detail, lung noise, rib\u2010lung contrast, rib sharpness, mediastinum detail, mediastinum noise, mediastinum alignment, subdiaphragm\u2010lung contrast, and subdiaphragm area. Metrics were compared across groups. To improve precision of means and confidence intervals for routine exams, an additional 66 PA images were acquired, processed, and pooled with Group 1. Three observer studies were conducted to assess whether humans were able to identify images classified by the algorithm as abnormal.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Metrics agreed with published Quality Consistency Ranges with three exceptions: higher lung gray level, lower rib\u2010lung contrast, and lower subdiaphragm\u2010lung contrast. Higher (stored) bit depth (14 vs 12) accounted for higher lung gray level values in our images. Values were most internally consistent for Group 1. The most sensitive metric for distinguishing between groups was mediastinum noise, followed closely by lung noise. The least sensitive metrics were mediastinum detail and rib\u2010lung contrast. The algorithm was more sensitive than human observers at detecting suboptimal diagnostic quality images.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The software appears promising for objectively and automatically identifying suboptimal images in a clinical imaging operation. The results can be used to establish local quality consistency ranges and action limits per facility preferences.<\/jats:p><\/jats:sec>","DOI":"10.1002\/mp.13107","type":"journal-article","created":{"date-parts":[[2018,7,27]],"date-time":"2018-07-27T17:05:19Z","timestamp":1532711119000},"page":"4377-4391","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Automated quality control assessment of clinical chest images"],"prefix":"10.1002","volume":"45","author":[{"given":"Charles E.","family":"Willis","sequence":"first","affiliation":[{"name":"Department of Imaging Physics The University of Texas MD Anderson Cancer Center Houston TX 77030 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas K.","family":"Nishino","sequence":"additional","affiliation":[{"name":"Department of Imaging Physics The University of Texas MD Anderson Cancer Center Houston TX 77030 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jered R.","family":"Wells","sequence":"additional","affiliation":[{"name":"Clinical Imaging Physics Group Duke University Medical Center Durham NC 27705 USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.
