Systems and methods for accelerated multi-contrast propeller

Systems and methods for accelerated multi-contrast PROPELLER are disclosed herein. A K-space is sampled in a rotating fashion by using a plurality of radially directed blades around a center of k-space. A first subset of blades is acquired for a first contrast, and a second subset of blades is acquired for a second contrasts. The first subset of blades is combined with the high frequency components of the second subset of blades to produce an image of the first contrast, and the second subset of blades are combined with high frequency components of the first subset of blades to produce an image of the second contrast. 本文公开了加速多对比度PROPELLER的系统和方法。使用围绕k空间中心的多个径向指向的叶片以旋转方式对k空间进行采样。为第一对比度获取第一叶片子集，并且为第二对比度获取第二叶片子集。组合第一叶片子集和第二叶片子集的高频分量，以产生第一对比度的图像。以及组合第二叶片子集和第一叶片子集的高频分量，以产生第二对比度的图像。
