عنوان انگلیسی Development of A Head Docking Device for Linac-based Stereotactic Radiosurgery System to be Installed on Neptun 10 PC Linac
چکیده انگلیسی مقاله Introduction: Stereotactic radiosurgery is a technique for the treatment of intracranial lesions with highly collimated x-ray beam. Linac-based radiosurgery is currently performed by two techniques: couch or pedestal mounted. In the first technique, a device is required to affix patient's head to a couch and moreover to translate it accurately. Structure of such a device constructed by the authors in addition to the acceptance test which was performed to evaluate the device has been described in this article. Materials and Methods: A head docking device has been designed and constructed according to the geometry of linac's couch and desired functions. The device is completely made from aluminum and consists of four major components: attachment bar, lower structure with four movements, upper structure with two movements equipped with a lock, two handles and a mounting ring for stereotactic frame. Translating accuracy, mechanical stability and isocentric accuracy were assessed in the frame of acceptance test. Results: Translating accuracy, mechanical stability and isocentric accuracy within 95% confidence intervals were found to be 1, 1.64 and 3.2 mm, respectively. Discussion and Conclusion: According to AAPM report no.54 recommendation head docking device should translate head with accuracy of 1 mm, the property which was met by the constructed device. Moreover considering the measured isocentric accuracy, encompassing mechanical stability, constructed device can confidently be used in stereotactic treatment.
