The routine clinical use of gated SPECT is inhibited by sophisticated, time-consuming processing techniques. The present paper describes a new technique for the simultaneous three-dimensional presentation of the amplitude and phase of the first Fourier harmonics, with the aim of obtaining detailed information about the ventricular motion in a relatively short time, from each angle of view of three-dimensional space. The method is simple and robust, and processing is automatic. It does not need carefully elaborated techniques for surface determination, because the cardiac surface is merely used as a reference skeleton onto which the functional information of amplitude and phase is mapped. The Fourier analysis before reconstruction results in running times shorter than 15 min and may further open the way for the routine use of gated SPECT.
门控单光子发射计算机断层扫描（gated SPECT）的常规临床应用受到复杂且耗时的处理技术的限制。本文描述了一种用于同时三维呈现第一傅里叶谐波的幅度和相位的新技术，目的是在相对较短的时间内从三维空间的每个视角获取有关心室运动的详细信息。该方法简单且稳健，处理是自动的。它不需要精心设计的表面确定技术，因为心脏表面仅用作映射幅度和相位功能信息的参考骨架。重建前的傅里叶分析运行时间短于15分钟，可能会进一步为门控SPECT的常规应用开辟道路。
