Abstract
Power spectrum or magnitude images are frequently presented in magnetic resonance imaging. In such images, measurement of signal intensity at low signal levels is compounded with the noise. This report describes how to extract true intensity measurements in the presence of noise.
摘要
功率谱或幅度图像在磁共振成像中经常出现。在这类图像中，低信号水平下信号强度的测量会受到噪声的影响。本报告描述了如何在存在噪声的情况下提取真实的强度测量值。
