The spatial frequency (k) space concept is extended to describe the imaging of time-dependent objects. This work builds on the existing k-space description of MRI and is useful for simplifying the analysis of explanations of motion artifacts, algorithms for the correction of motion, and efficient imaging schemes for dynamic objects. Specific examples of the use of this concept for different imaging techniques are presented.
空间频率（k）空间概念被扩展用于描述随时间变化的物体的成像。这项工作基于磁共振成像（MRI）现有的k空间描述，有助于简化对运动伪影解释的分析、运动校正算法以及动态物体的高效成像方案。文中给出了该概念在不同成像技术中应用的具体示例。
