At the level of the target to be treated, where the beams are concentrated, the radiation doses delivered by the different beams add up, generating a high dose in a single session, giving the desired therapeutic effect. Surrounding and distant tissues will only be crossed by a small number of beams, and therefore only a small, non-deleterious dose of radiation.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"wp-image-4559 aligncenter load-finished\" src=\"https:\/\/www.neurochirurgie-lariboisiere.com\/wp-content\/uploads\/6-Figure2-1.png\" sizes=\"(max-width: 848px) 100vw, 848px\" srcset=\"https:\/\/www.neurochirurgie-lariboisiere.com\/wp-content\/uploads\/6-Figure2-1.png 1000w, https:\/\/www.neurochirurgie-lariboisiere.com\/wp-content\/uploads\/6-Figure2-1-300x294.png 300w, https:\/\/www.neurochirurgie-lariboisiere.com\/wp-content\/uploads\/6-Figure2-1-768x753.png 768w\" alt=\"\" width=\"848\" height=\"831\"><\/p>\n<p>Radiosurgery therefore has the advantage of avoiding the risks and possible complications or contraindications of conventional neurosurgical intervention for these deep lesions.<\/p>\n<p>It is also an essential adjunct when surgery has not, by choice, made it possible to remove the entire lesion, in order to reduce the risks of surgery.<\/p>\n<p>It is also a very useful solution in the event of residual growth or tumor recurrence, as an alternative to repeat surgery.<\/p>\n<\/div>\n\t\t\t\t\t\t\t\t\t<div class=\"elementor-tab-title elementor-tab-mobile-title\" aria-selected=\"false\" data-tab=\"2\" role=\"tab\" tabindex=\"-1\" aria-controls=\"elementor-tab-content-2682\" aria-expanded=\"false\">History of radiosurgery<\/div>\n\t\t\t\t\t<div id=\"elementor-tab-content-2682\" class=\"elementor-tab-content elementor-clearfix\" data-tab=\"2\" role=\"tabpanel\" aria-labelledby=\"elementor-tab-title-2682\" tabindex=\"0\" hidden=\"hidden\"><p><strong>Radiosurgery was born of neurosurgeons&#8217; expertise in<\/strong> cranial <strong>stereotaxis<\/strong>, which consists in locating and targeting deep intracranial zones using a three-dimensional coordinate system.<\/p>\n<p>These stereotactic techniques were then applied to radiotherapy by neurosurgeons, giving rise to <strong>radiosurgery<\/strong>:<\/p>\n<ul>\n<li>Gamma-knife: the first device was invented in 1951 by a Swedish neurosurgeon (Prof. Karl Leksell).<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"size-full wp-image-4563 aligncenter load-finished\" src=\"https:\/\/www.neurochirurgie-lariboisiere.com\/wp-content\/uploads\/Gamma.JPG.jpg\" sizes=\"(max-width: 392px) 100vw, 392px\" srcset=\"https:\/\/www.neurochirurgie-lariboisiere.com\/wp-content\/uploads\/Gamma.JPG.jpg 392w, https:\/\/www.neurochirurgie-lariboisiere.com\/wp-content\/uploads\/Gamma.JPG-300x237.jpg 300w\" alt=\"\" width=\"392\" height=\"310\"><\/p>\n<ul>\n<li><strong>The Cyberknife, a &#8220;multi-purpose, multi-organ&#8221; radiosurgery device, was then <\/strong>developed in the late 80s by Stanford neurosurgeon Prof. John Adler.<\/li>\n<\/ul>\n<p>In France, radiosurgery (LINAC) began in 1984 thanks to Prof. Betti, a neurosurgeon and student of Prof. Talairach, head of the neurosurgery department at H\u00f4pital Sainte-Anne and a world pioneer in stereotaxy.
