The purpose of this study was to develop a remote\u2010controlled and self\u2010contained audiovisual (AV)\u2010aided interactive system with the iPad mini with Retina display for intrafractional motion management in brain\/H&amp;N (head and neck) radiotherapy for claustrophobic patients. The self\u2010contained, AV\u2010aided interactive system utilized two tablet computers: one for AV\u2010aided interactive guidance for the subject and the other for remote control by an operator. The tablet for audiovisual guidance traced the motion of a colored marker using the built\u2010in front\u2010facing camera, and the remote control tablet at the control room used infrastructure Wi\u2010Fi networks for real\u2010time communication with the other tablet. In the evaluation, a programmed QUASAR motion phantom was used to test the temporal and positional accuracy and resolution. Position data were also obtained from ten healthy volunteers with and without guidance to evaluate the reduction of intrafractional head motion in simulations of a claustrophobic brain or H&amp;N case. In the phantom study, the temporal and positional resolution was 24 Hz and 0.2 mm. In the volunteer study, the average superior\u2013inferior and right\u2013left displacement was reduced from 1.9 mm to 0.3 mm and from 2.2 mm to 0.2 mm with AV\u2010aided interactive guidance, respectively. The superior\u2013inferior and right\u2013left positional drift was reduced from 0.5 mm\/min to 0.1 mm\/min and from 0.4 mm\/min to 0.04 mm\/min with audiovisual\u2010aided interactive guidance. This study demonstrated a reduction in intrafractional head motion using a remote\u2010controlled and self\u2010contained AV\u2010aided interactive system of iPad minis with Retina display, easily obtainable and cost\u2010effective tablet computers. This approach can potentially streamline clinical flow for claustrophobic patients without a head mask and also allows patients to practice self\u2010motion management before radiation treatment delivery.<\/jats:p><jats:p>PACS number: 87.55.Gh<\/jats:p>","DOI":"10.1120\/jacmp.v16i3.5359","type":"journal-article","created":{"date-parts":[[2017,2,27]],"date-time":"2017-02-27T23:59:40Z","timestamp":1488239980000},"page":"216-224","source":"Crossref","is-referenced-by-count":5,"title":["Development of a novel remote\u2010controlled and self\u2010contained audiovisual\u2010aided interactive system for immobilizing claustrophobic patients"],"prefix":"10.1002","volume":"16","author":[{"given":"Harang","family":"Ju","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology University of Virginia Health System  Charlottesville VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Siyong","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology Virginia Commonwealth University  Richmond VA USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paul","family":"Read","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Virginia Health System  Charlottesville VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Trifiletti","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Virginia Health System  Charlottesville VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Harrell","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Virginia Health System  Charlottesville VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bruce","family":"Libby","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Virginia Health System  Charlottesville VA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taeho","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology University of Virginia Health System  Charlottesville VA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2015,5,8]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2008.06.1937"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0167-8140(00)00192-4"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1118\/1.4814792"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijrobp.2004.01.025"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(97)00075-8"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1120\/jacmp.v14i5.4400"},{"key":"e_1_2_7_8_1","unstructured":"HelmigRDandKimS.Interactive patient immobilization system [patent].
