Use of 3D printers to create a patient?specific 3D bolus for external beam therapy |pdf=|usr=}}{{26103485}} gab.com Text Use of 3D printers to create a patient specific 3D bolus for external beam therapy JO: J Appl Clin Med Phys http://www.kidney.de/pget.php?&tw=1&pmid=26103485 #FOAvip The purpose of this paper is to demonstrate that an inexpensive 3D printer can be used to manufacture patient?specific bolus for external beam therapy, and to show we can accurately model this printed bolus in our treatment planning system for accurate treatment delivery. Percent depth?dose measurements and tissue maximum ratios were used to determine the characteristics of the printing materials, acrylonitrile butadiene styrene and polylactic acid, as bolus material with physical density of 1.04 and 1.2?g/cm3, and electron density of 3.38×1023electrons/cm3 and 3.80×1023?electrons/cm3, respectively. Dose plane comparisons using Gafchromic EBT2 film and the RANDO phantom were used to verify accurate treatment planning. We accurately modeled a printing material in Eclipse treatment planning system, assigning it a Hounsfield unit of 260. We were also able to verify accurate treatment planning using gamma analysis for dose plane comparisons. With gamma criteria of 5% dose difference and 2 mm DTA, we were able to have 86.5% points passing, and with gamma criteria of 5% dose difference and 3 mm DTA, we were able to have 95% points passing. We were able to create a patient?specific bolus using an inexpensive 3D printer and model it in our treatment planning system for accurate treatment delivery.PACS numbers: 87.53.Jw, 87.53.Kn, 87.56.ng Twit Text FOAVip Use of 3D printers to create a patient specific 3D bolus for external beam therapy ????J Appl Clin Med Phys http://www.kidney.de/pget.php?&tw=1&pmid=26103485 #FOAvip Twit Text # Free Paper on # # # # # LINK http://www.kidney.de/pget.php?&tw=1&pmid=26103485 #FOAvip English Wikipedia <ref>{{Cite pmid|26103485}}</ref> Use of 3D printers to create a patient?specific 3D bolus for external beam therapy #MMPMID26103485 Burleson S; Baker J; Hsia AT; Xu Z J Appl Clin Med Phys 2015[May]; 16 (3): 166-78 PMID26103485show ga The purpose of this paper is to demonstrate that an inexpensive 3D printer can be used to manufacture patient?specific bolus for external beam therapy, and to show we can accurately model this printed bolus in our treatment planning system for accurate treatment delivery.
