摘要

The single-shot spiral magnetic resonance imaging (MRI) technique was implemented and optimized on a Bruker Biospec47/30 scanner. The technique includes the pulse sequence for generation and detection of the k-space MRI signal (free induction decay (FID)), and PC-based programs for the data grid and image reconstruction.The temporal resolution is 70ms (14 images per second), which consists of a data acquisition time as short as 13.7 ms, a spin-echo time of 13.6 ms and a magnetization recovery time of 43 ms. This makes it possible to take real-time images of moving objects. The technique is demonstrated using a pendulum (tube) filled with water.
