Magnetic resonance imaging (MRI) is a powerful tool which enables the visualization of anatomy and the assessment of many physiological aspects of organ function. MRI and magnetic resonance angiography and magnetic resonance spectroscopy will play critical roles in cardiac applications during the next millennium. Thus, it is important to have a basic understanding of the most important physical processes in MR--the generation of nuclear magnetic resonance signals and their transformation into images. A conceptual description of these processes is the primary focus of this article. Also discussed are some additional signal manipulations specific to the needs of cardiac MRI, a field readily identified as the most significant in modern MRI technology development.
磁共振成像（MRI）是一种强大的工具，它能够实现解剖结构的可视化以及对器官功能诸多生理方面的评估。在未来一千年里，MRI、磁共振血管造影和磁共振波谱将在心脏应用中发挥关键作用。因此，对磁共振成像中最重要的物理过程——核磁共振信号的产生及其转化为图像——有一个基本的了解很重要。本文主要关注对这些过程的概念性描述。同时还讨论了一些针对心脏MRI需求的额外信号处理方法，心脏MRI领域被公认为是现代MRI技术发展中最重要的领域。
