In order to facilitate intra-operative use of magnetic resonance imaging (MRI) in neurosurgery an MRI-compatible headholder was developed and adapted to a modified MR-couch simultaneously serving as tabletop for the operating table. To allow shock-free transport into the scanner the wheels of the operating table were replaced by an air cushion mechanism. In 75 procedures the system proved to be reliable and safe. Image quality was not impaired by the fixation device. With growing routine the transfer became straightforward, requiring approximately 10 min. Intra-operative MRI is thus made possible with minimal changes to the standard surgical environment. Its benefit however, still remains to be critically investigated.
为便于在神经外科手术中使用磁共振成像（MRI），研发了一种与MRI兼容的头架，并将其适配到一个经过改良的MR手术床，该手术床同时用作手术台的桌面。为了能无冲击地转运至扫描仪，手术台的轮子被气垫装置所取代。在75例手术中，该系统被证明是可靠且安全的。固定装置未损害图像质量。随着使用越来越常规化，转运变得简单直接，大约需要10分钟。因此，在对标准手术环境进行最小改动的情况下即可实现术中MRI。然而，其益处仍有待严格研究。
