Faraj","Mustafa Salih Al-Musawi","Tabarek Ali Abdulameer"],"abstract":"Background: This study evaluates an alternative to the classical method of head fixation during Gamma Knife radiosurgery using a Leksell head frame. In the Gamma Knife® Icon™ model, a new method of head fixation is used by utilizing a thermal molded polymer mask that takes the shape of the patient’s head before fixing the head to the table. However, this mask is for single use and quite expensive. Methods: We describe a new, very economical method to fix the head of the patient during radiosurgery. We used commercial, quite cheap material [polylactic acid (PLA)] plastic and made a 3D printing model for the patient’s face, taking special measurements to put this mask and fix it on the Gamma Knife. The actual material cost is only $4 (100 times less than the original mask cost). Results: The new mask efficiency was tested using the movement checker software, the same one used to measure the efficiency of the original mask. Conclusion: The newly designed and manufactured mask is quite effective for use with the Gamma Knife® Icon™, with a much lower cost, and it can be manufactured locally.","thumbnailUrl":"https://sni-digital-videos.s3.amazonaws.com/articles/3a0bf485-a780-4c6b-a758-bae4f92e8bb8/featured/hero-1781560275363.png","publishDate":"2023-06-02T00:00:00.000Z","doi":"10.25259/SNI_1053_2022","categories":["Stereotactic","Technical Note"],"fullTextUrl":"https://surgicalneurologyint.com/wp-content/uploads/2023/06/12348/SNI-14-188.pdf"}
