QA records were reviewed for dose difference (single point with ion chamber measurement;\n \n agreement criteria) and percentage of pixels passing relative dose gamma analysis (film measurement; 90% passing 5%(global)\/3 mm agreement criteria) from 2005 through 2011. Plan records were analyzed for trends with measurement date and treatment site. Plans failing to meet QA tolerance criteria were evaluated for follow\u2010up clinical action (i.e., if repeat measurements were performed). The mean difference (\n \n ) between ion chamber point measurements and calculated doses was\n \n \n (calculated values being slightly higher) and, regarding planar dose evaluations, the mean percentage of pixels passing the gamma criteria of 5%(global)\/3 mm was 97.7% (lower 95th percentile: 92.2%). 97.7% and 99.3% of plans passed the point dose and planar dose verification, respectively. We observed statistically significant differences (\n \n ) in both point dose and planar dose verification measurements as a function of treatment site (particularly for stereotactic spine and mesothelioma sites) and measurement date (average agreement improved with time). However, despite improved dosimetric agreement, the percentage of failing plans has remained nearly constant at 2.3%.\n <\/jats:p>\n PACS numbers: 87.55.Qr, 87.55.km, 87.56.Fc<\/jats:p>","DOI":"10.1120\/jacmp.v15i5.4935","type":"journal-article","created":{"date-parts":[[2017,2,27]],"date-time":"2017-02-27T18:39:09Z","timestamp":1488220749000},"page":"196-206","source":"Crossref","is-referenced-by-count":39,"title":["A six\u2010year review of more than 13,000 patient\u2010specific IMRT QA results from 13 different treatment sites"],"prefix":"10.1002","volume":"15","author":[{"given":"Kiley B.","family":"Pulliam","sequence":"first","affiliation":[{"name":"The University of Texas Graduate School of Biomedical Sciences at Houston Houston TX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Followill","sequence":"additional","affiliation":[{"name":"Department of Radiation Physics The University of Texas MD Anderson Cancer Center Houston TX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laurence","family":"Court","sequence":"additional","affiliation":[{"name":"Department of Radiation Physics The University of Texas MD Anderson Cancer Center Houston TX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lei","family":"Dong","sequence":"additional","affiliation":[{"name":"The University of Texas Graduate School of Biomedical Sciences at Houston Houston TX"},{"name":"Department of Radiation Oncology Scripps Proton Therapy Center San Diego CA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael","family":"Gillin","sequence":"additional","affiliation":[{"name":"Department of Radiation Physics The University of Texas MD Anderson Cancer Center Houston TX"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karl","family":"Prado","sequence":"additional","affiliation":[{"name":"University of Maryland School of Medicine Baltimore MD USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen F.","family":"Kry","sequence":"additional","affiliation":[{"name":"Department of Radiation Physics The University of Texas MD Anderson Cancer Center Houston TX"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2014,9,8]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.4736949"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3633904"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3397807"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.radonc.2007.11.007"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.4711755"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3425781"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3544657"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3238104"},{"key":"e_1_2_7_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(03)00197-4"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1186\/1748-717X-6-85"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1088\/0031-9155\/56\/23\/007"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1120\/jacmp.v8i3.2448"},{"key":"e_1_2_7_14_1","volume-title":"An evaluation of the consistency of IMRT patient\u2010specific QA techniques [thesis]","author":"McKenzie EM","year":"2013"},{"key":"e_1_2_7_15_1","doi-asserted-by":"publisher","DOI":"10.1120\/jacmp.v9i3.2721"}],"container-title":["Journal of Applied Clinical Medical Physics"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1120%2Fjacmp.v15i5.4935","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1120%2Fjacmp.v15i5.4935","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/aapm.onlinelibrary.wiley.com\/doi\/pdf\/10.1120\/jacmp.v15i5.4935","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,5]],"date-time":"2023-10-05T16:33:14Z","timestamp":1696523594000},"score":1,"resource":{"primary":{"URL":"https:\/\/aapm.onlinelibrary.wiley.com\/doi\/10.1120\/jacmp.v15i5.4935"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014,9]]},"references-count":14,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2014,9]]}},"alternative-id":["10.1120\/jacmp.v15i5.4935"],"URL":"https:\/\/doi.org\/10.1120\/jacmp.v15i5.4935","archive":["Portico"],"relation":{},"ISSN":["1526-9914","1526-9914"],"issn-type":[{"value":"1526-9914","type":"print"},{"value":"1526-9914","type":"electronic"}],"subject":[],"published":{"date-parts":[[2014,9]]}}}
