A new method is described that modifies the original concept of parametric or functional imaging. While the conventional parametric image replaces a temporal sequence of images with a single static image based upon a selected parameter, in the new approach fixed zonal areas and bands are established within the imaged organ, and the mean value for each zone is computed. It is shown that parametric images can be quantified and objectively compared in this way. The algorithm has been implemented to analyze renal studies.
本文描述了一种新方法，该方法修改了参数成像或功能成像的原始概念。传统的参数图像是基于选定参数用单个静态图像取代图像的时间序列，而在新方法中，在成像器官内建立固定的区域和带，并计算每个区域的平均值。结果表明，通过这种方式可以对参数图像进行量化和客观比较。该算法已被用于分析肾脏研究。
