已经开发了用于闪烁照相机的心肌图像的在线计算机增强和用于显示心肌中的相对铊-201活性的图形表示的方法。增强使用快速傅立叶变换技术。该方法已被应用到多个图像后获得的压力和4- 5小时的休息。心肌梗死和/或短暂性缺血患者进行了评估，并提出了典型的例子。
Methods have been developed for on-line computer enhancement of a scintillation camera's myocardial images and for a graphical presentation showing relative thallium-201 activity in the myocardium. Enhancement uses fast Fourier transform techniques. The methods have been applied to multiple images obtained after stress and 4--5 hr rest. Patients with myocardial infarction and/or transient ischemia were evaluated and typical examples are presented.
