Interventional surgery techniques under the control of fast acquired magnetic resonance (MR) images may become important in interventional radiology in the near future. One of the components needed for an interventional MR scanner is the real-time reconstruction of the acquired MR images. However up to now no real-time reconstruction systems are readily available for MR images. Therefore a reconstruction device was developed, which allows reconstruction and display of MR images with a delay of less than 50 ms. Additional to the high performance, the main characteristics of the presented device are its full compatibility with different MR acquisition techniques and its moderate cost. The device can be operated with most types of commercial scanners. It is especially suited for interventional MR systems but has also applications with conventional MR scanners.
在快速采集的磁共振（MR）图像控制下的介入手术技术在不久的将来可能会在介入放射学中变得重要。介入式MR扫描仪所需的组件之一是对采集到的MR图像进行实时重建。然而，到目前为止，还没有适用于MR图像的实时重建系统。因此，开发了一种重建设备，它能够以小于50毫秒的延迟重建并显示MR图像。除了高性能之外，该设备的主要特点是它与不同的MR采集技术完全兼容且成本适中。该设备可以与大多数类型的商业扫描仪一起操作。它特别适用于介入式MR系统，但也可应用于传统MR扫描仪。
