The method assumes a correlation between the patients\u2019 tissue equivalent thickness and the square root of the ratio of the patient's weight to height. To assess variability in detector exposures, the EI statistics for 75 chest examinations and 99 abdominal portable X\u2010ray images acquired with the new technique chart were compared to those from a single portable unit (chest: 3877 images; abdomen: 200 images) using a conventional technique chart with three patient sizes, and to a stationary radiography room utilizing automatic exposure control (AEC) (chest: 360 images; abdomen: 112 images). The results showed that when using the new technique chart on a group of portable units, the variability in EI was significantly reduced (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.01) for both AP chest and AP abdomen images compared to the single portable using a standard technique chart with three patient sizes. The variability in EI for the images acquired with the new chart was comparable to the stationary X\u2010ray room with an AEC system (<jats:italic>p<\/jats:italic>\u00a0&gt;\u00a00.05). This method could be used to streamline the entire imaging chain by automatically selecting an X\u2010ray technique based on patient demographic information contained in the MWL to provide higher quality examinations to clinicians by eliminating outliers. In addition, patient height and weight can be used to estimate the patients\u2019 tissue equivalent thickness.<\/jats:p>","DOI":"10.1002\/acm2.13582","type":"journal-article","created":{"date-parts":[[2022,3,9]],"date-time":"2022-03-09T13:17:18Z","timestamp":1646831838000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Method of determining technique from weight and height to achieve targeted detector exposures in portable chest and abdominal digital radiography"],"prefix":"10.1002","volume":"23","author":[{"given":"Matthew","family":"Hoerner","sequence":"first","affiliation":[{"name":"Department of Radiology and Biomedical Imaging Yale University and Yale New Haven Hospital  New Haven Connecticut USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kevin","family":"Grizzard","sequence":"additional","affiliation":[{"name":"Department of Radiology and Biomedical Imaging Yale New Haven Hospital  New Haven Connecticut USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jennifer","family":"Moroz","sequence":"additional","affiliation":[{"name":"Department of Radiology Brigham and Women's Hospital  Boston Massachusetts USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,3,9]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejmp.2018.12.009"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmrs.66"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmrs.56"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejmp.2019.05.011"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12194-015-0341-2"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00247-010-1954-6"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.3121505"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/mp.13212"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.1002\/jmrs.49"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1093\/rpd\/nch562"},{"issue":"1","key":"e_1_2_9_12_1","first-page":"76271F\u201076271F\u20101","article-title":"Quantification of radiographic image quality based on patient anatomical contrast\u2010to\u2010noise ratio: a preliminary study with chest images","volume":"7627","author":"Lin Y","year":"2010","journal-title":"Proc SPIE"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0032-1312727"},{"issue":"4","key":"e_1_2_9_14_1","first-page":"202","article-title":"Pegged kolovolt technique","volume":"37","author":"Funke T","year":"1966","journal-title":"Radiol Technol"},{"key":"e_1_2_9_15_1","first-page":"51","article-title":"Tissue absorption theory applied to formulation of radiographic technique resulting in time as the variable factor","volume":"37","author":"McDaniel CT","year":"1965","journal-title":"Radiol Technol"},{"key":"e_1_2_9_16_1","first-page":"62494","volume-title":"Medical electrical equipment\u2013exposure index of digital X\u2010ray imaging systems\u2010Part 1: Definitions and requirements for general radiography","author":"Commission","year":"2008"},{"key":"e_1_2_9_17_1","unstructured":"GoldstoneKE.Tissue substitutes in radiation dosimetry and measurement.
