利用高速个人计算机开发了一种实时核磁共振图像重建和显示系统，并针对32位多任务微软Windows 95操作系统进行了优化。通过改变主板时钟频率和处理器/总线频率比，系统在不同的CPU时钟频率下运行。在200 MHz时钟频率下使用奔腾CPU时，一张128 × 128像素图像的重构时间为48 ms，而在放大后的256 × 256像素窗口上显示图像的重构时间约为8 ms。采用三种快速成像序列（FLASH、多镜头EPI和单镜头EPI）进行核磁共振成像实验，以验证系统的实时性。因此，在大多数情况下，高速PC是实时MRI图像重建和显示系统的最佳选择。
A real-time NMR image reconstruction and display system was developed using a high-speed personal computer and optimized for the 32-bit multitasking Microsoft Windows 95 operating system. The system was operated at various CPU clock frequencies by changing the motherboard clock frequency and the processor/bus frequency ratio. When the Pentium CPU was used at the 200 MHz clock frequency, the reconstruction time for one 128 x 128 pixel image was 48 ms and that for the image display on the enlarged 256 x 256 pixel window was about 8 ms. NMR imaging experiments were performed with three fast imaging sequences (FLASH, multishot EPI, and one-shot EPI) to demonstrate the ability of the real-time system. It was concluded that in most cases, high-speed PC would be the best choice for the image reconstruction and display system for real-time MRI.
