Because the boost is considered a simple treatment, CT\u2010based treatment planning is rarely used. Further, the results of such a plan might be inaccurate, as the complex dose distribution surrounding the stoma air cavity is poorly modeled by many treatment planning systems. We constructed three phantoms\u2014two with a central vertical cavity to mimic the size and shape of the stoma and proximal trachea and one with a cavity inclined at 45\u00b0 to the horizontal to better simulate anatomy. These were used to investigate the dose distribution surrounding the stoma. In all cases, the entrance to the stoma opening was centered in a field defined by a 7\u2010cm circular cutout and the phantom was irradiated at a source\u2010surface distance (SSD) of 100 cm with either vertically incident 9\u2010 or 12\u2010MeV electrons. Film measurements were made at a range of depths below and lateral to the cavity. For the vertical cavity phantoms, diode measurements were performed and isodose plans using CT scans of the phantoms were generated on a modern treatment planning system. For these two phantoms, the combined effects of lateral scatter from surrounding material and reduced equivalent thickness for electrons which pass directly through the cavity increases the dose within a centimeter of the bottom of cavity by as much as 50% for 9 MeV and 70% for 12 MeV. In material at the shallower (\u201csuperior\u201d) end of the inclined cavity, a\n \n overdose was noted. The dose increase is geometry dependent and is not predicted by the available treatment planning system. The potential of such a dose increase to affect normal tissues such as the neopharynx should be considered.\n <\/jats:p>\n PACS number(s): 87.53.\u2013j, 87.66.\u2013a<\/jats:p>","DOI":"10.1120\/jacmp.v2i1.2626","type":"journal-article","created":{"date-parts":[[2007,2,22]],"date-time":"2007-02-22T17:02:42Z","timestamp":1172163762000},"page":"9-20","source":"Crossref","is-referenced-by-count":2,"title":["The dose distribution of medium energy electron boosts to the laryngectomy stoma"],"prefix":"10.1002","volume":"2","author":[{"given":"Ellen D.","family":"Yorke","sequence":"first","affiliation":[{"name":"Memorial Sloan\u2010Kettering Cancer Center 1275 York Avenue New York New York 10021"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alireza","family":"Kassaee","sequence":"additional","affiliation":[{"name":"University of Pennsylvania 3400 Spruce Street Philadelphia Pennsylvania 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Todd","family":"Doyle","sequence":"additional","affiliation":[{"name":"University of Pennsylvania 3400 Spruce Street Philadelphia Pennsylvania 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Laurie A.","family":"Loevner","sequence":"additional","affiliation":[{"name":"University of Pennsylvania 3400 Spruce Street Philadelphia Pennsylvania 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David I.","family":"Rosenthal","sequence":"additional","affiliation":[{"name":"University of Pennsylvania 3400 Spruce Street Philadelphia Pennsylvania 19104"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2001,1]]},"reference":[{"key":"e_1_2_5_1_1","doi-asserted-by":"publisher","DOI":"10.1148\/85.3.524"},{"key":"e_1_2_5_2_1","volume-title":"The Physics of Radiation Therapy","author":"Khan F.
