Abstract

A new 3D Fourier imaging method based on sparse radial scanning (SRS-FT) ofkspace is proposed. It allows acquisition of FIDs and is therefore well suited to imaging objects with very shortT2. Use of a Bayesian procedure allows (1) an important reduction of scan time to below that of the projection-reconstruction (PR) method by reducing the number of “Cartesian radial” encoding directions, and (2) a good image quality by estimating missing and corrupted Cartesian samples. SRS-FT images reconstructed from FIDs are compared to conventional FT and PR images.

SRS-FT是一种基于稀疏径向扫描和贝叶斯估计的傅里叶成像方法
提出了一种基于空间稀疏径向扫描(SRS-FT)的三维傅里叶成像方法。它允许获取fid,因此非常适合成像具有非常短的tt2的物体。贝叶斯过程的使用允许(1)通过减少“笛卡尔径向”编码方向的数量,将扫描时间大大减少到低于投影重建(PR)方法的扫描时间;(2)通过估计缺失和损坏的笛卡尔样本,获得良好的图像质量。将FIDs重建的SRS-FT图像与传统的FT和PR图像进行了比较。
