本文报告可供CT、MRI和普通X线造影定位的通用多功能立体定向仪。此装置由固定器、定位架、导向器和附件等组成。在作CT扫描时,用附件能将定位架固定在CT床上,其定位与CT扫描层一致。因此,不必计算就能直接测量目标的位置。经近百次的定位试验表明,用这种方法定位可靠且精确。 This article reports a versatile, versatile stereotactic device that can be used for CT, MRI, and plain radiography. This device consists of fixtures, positioning frame, guides and accessories and other components. In the CT scan, with the attachment can be fixed in the CT positioning of the bed, its positioning consistent with the CT scan layer. Therefore, you can measure the position of the target directly without having to calculate it. After nearly a hundred times positioning test shows that using this method to locate reliable and accurate.
