The film-screen images were digitized using pixel sizes of 115, 170, and 340 \u03bcm along with 170 \u03bcm with a 10; 1 wavelet compression. The digital images were displayed on a 1280\u00d71024\u00d78 bits monitor, and 5 observers evaluated the images in 5 randomized sessions. The results for each pixel size were then compared to the film-screen images by ROC analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The mean area under the ROC curves was larger for the film-screen images than for the digital images at all resolutions. However, this difference was not significant when the areas under the ROC curves for the film-screen images were compared to the digital images of 115, 170, and 170 \u03bcm with 10: 1 compression. There was a significant difference for the 340-\u03bcm pixel size in favour of the film-screen images. The mean ROC curves for the digital images were very similar for the 115 and 170 \u03bcm pixel sizes, although slightly better for 115 \u03bcm. At 170 \u03bcm, the compression seemed to have a relatively small negative effect on the diagnostic performance; the deterioration was greater when the pixel size was increased to 340 \u03bcm. There was no obvious correlation between diagnostic performance and the experience of the observers in using workstations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The pixel size of 170 \u03bcm is adequate for the detection of subtle fractures, even after wavelet compression by a ratio of 10:1.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/02841851960373p226","type":"journal-article","created":{"date-parts":[[2015,6,11]],"date-time":"2015-06-11T06:26:50Z","timestamp":1434004010000},"page":"555-560","source":"Crossref","is-referenced-by-count":9,"title":["Spatial Resolution Requirements in Digital Radiography of Scaphoid Fractures"],"prefix":"10.1177","volume":"37","author":[{"given":"\u00c1.","family":"J\u00f3nsson","sequence":"first","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Laurin","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Karner","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Herrlin","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Hochbergs","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.","family":"Jonsson","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"O.","family":"Rudling","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Sandstr\u00f6m","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Sloth","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Svahn","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Pettersson","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, University Hospital, Lund, Sweden."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1996,5,1]]},"reference":[{"key":"bibr1-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.186.1.8416576"},{"key":"bibr2-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1259\/0007-1285-67-793-1"},{"key":"bibr3-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.189.1.55a"},{"key":"bibr4-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.2214\/ajr.163.2.8037051"},{"key":"bibr5-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1148\/radiology.186.2.8421746"},{"key":"bibr6-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1016\/S0009-9260(05)81108-0"},{"key":"bibr7-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1097\/00004424-199003000-00014"},{"key":"bibr8-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1177\/028418519403500401"},{"key":"bibr9-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1177\/028418519503600316"},{"key":"bibr10-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1177\/028418519203300527"},{"key":"bibr11-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1016\/0169-2607(91)90062-X"},{"key":"bibr12-02841851960373P226","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.11.6.1749846"},{"key":"bibr13-02841851960373P226","first-page":"546","volume-title":"The physics of medical imaging.
