Data were analyzed in patients in whom the following diagnoses had been made: vestibular schwannoma, pituitary adenoma, meningioma, solitary metastasis, and other benign and malignant solitary tumors. Patients with arteriovenous malformations, ocular lesions, and functional diagnoses were excluded from this study.<\/jats:p><jats:p content-type=\"fine-print\"><jats:italic>Conclusions.<\/jats:italic>With the C model there was a better conformity for most treated targets, such as vestibular schwannomas (p = 0.005) and meningiomas (p = 0.015). The level of radiation exposures to personnel was significantly decreased when using the model C (p &lt; 0.001). There was no significant difference in radiation exposure of extracranial structures for the same number of shots in patients treated by both models. The mean time saved using the C model with the APS was 41 minutes per treatment. It would seem that the gamma knife model C permits better dose conformity, shorter treatment times, and less radiation exposure to personnel.<\/jats:p>","DOI":"10.3171\/jns.2005.102.s_supplement.0025","type":"journal-article","created":{"date-parts":[[2009,5,13]],"date-time":"2009-05-13T18:11:12Z","timestamp":1242238272000},"page":"25-28","source":"Crossref","is-referenced-by-count":13,"title":["A comparison of the gamma knife model C and the Automatic Positioning System with Leksell model B"],"prefix":"10.3171","volume":"102","author":[{"given":"Daniela","family":"Tlachacova","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal","family":"Schmitt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Novotny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Josef","family":"Novotny","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mustafa","family":"Majali","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roman","family":"Liscak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"key":"b1","doi-asserted-by":"crossref","first-page":"164","DOI":"10.1159\/000100670","volume":"61","author":"Berk HW","year":"1993","journal-title":"Stereotact Funct Neurosurg"},{"key":"b2","doi-asserted-by":"crossref","first-page":"228","DOI":"10.3171\/jns.2000.93.supplement_3.0228","volume":"93","author":"Borden JA","year":"2000","journal-title":"J Neurosurg"},{"key":"b3","doi-asserted-by":"crossref","first-page":"1134","DOI":"10.1016\/S0360-3016(02)03025-0","volume":"4","author":"Bradford CD","year":"2002","journal-title":"Int J Radiat Oncol Biol Phys"},{"key":"b4","first-page":"1363","volume":"30","author":"Cheek D","year":"2003","journal-title":"Med Phys"},{"key":"b5","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(90)90326-F"},{"key":"b6","doi-asserted-by":"crossref","first-page":"193","DOI":"10.3171\/jns.2000.93.supplement_3.0193","volume":"93","author":"Horstmann GA","year":"2000","journal-title":"J Neurosurg"},{"key":"b7","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/S0090-3019(02)00742-5","volume":"58","author":"Ioffe V","year":"2002","journal-title":"Surg Neurol"},{"key":"b8","first-page":"374","volume":"4","author":"Jackie Wu QR","year":"2003","journal-title":"Med Phys"},{"key":"b9","doi-asserted-by":"crossref","first-page":"1169","DOI":"10.1016\/S0360-3016(98)00239-9","volume":"42","author":"Knoos T","year":"1998","journal-title":"Int J Radiat Oncol Biol Phys"},{"key":"b10","doi-asserted-by":"crossref","first-page":"233","DOI":"10.1016\/S0360-3016(99)00175-3","volume":"45","author":"Leung LH","year":"1999","journal-title":"Int J Radiat Oncol Biol Phys"},{"key":"b11","doi-asserted-by":"crossref","first-page":"1409","DOI":"10.1016\/S0360-3016(02)04599-6","volume":"55","author":"Lomax N","year":"2003","journal-title":"Int J Radiat Oncol Biol Phys"},{"key":"b12","doi-asserted-by":"crossref","first-page":"170","DOI":"10.1159\/000099686","volume":"66","author":"Novotny J","year":"1996","journal-title":"Stereotact Funct Neurosurg"},{"key":"b13","doi-asserted-by":"crossref","first-page":"219","DOI":"10.3171\/jns.2000.93.supplement_3.0219","volume":"93","author":"Paddick II","year":"2000","journal-title":"J Neurosurg"},{"key":"b14","doi-asserted-by":"publisher","DOI":"10.1016\/0360-3016(93)90548-A"},{"key":"b15","doi-asserted-by":"crossref","first-page":"197","DOI":"10.1159\/000078120","volume-title":"Radiosurgery.","volume":"5","author":"Smedt FD","year":"2004"},{"key":"b16","doi-asserted-by":"publisher","DOI":"10.1016\/S0360-3016(97)00720-7"},{"key":"b17","first-page":"553","volume":"41","author":"Yu C","year":"1997","journal-title":"Neurosurgery"}],"container-title":["Journal of Neurosurgery"],"original-title":[],"link":[{"URL":"https:\/\/thejns.org\/view\/journals\/j-neurosurg\/102\/11806\/article-p25.xml","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/thejns.org\/doi\/pdf\/10.3171\/jns.2005.102.s_supplement.0025","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,5,20]],"date-time":"2019-05-20T01:55:40Z","timestamp":1558317340000},"score":1,"resource":{"primary":{"URL":"http:\/\/thejns.org\/doi\/10.3171\/sup.2005.102.s_supplement.0025"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2005,1]]},"references-count":17,"URL":"https:\/\/doi.org\/10.3171\/jns.2005.102.s_supplement.0025","relation":{},"ISSN":["0022-3085"],"issn-type":[{"value":"0022-3085","type":"print"}],"subject":[],"published":{"date-parts":[[2005,1]]}}}
