A method to study the loss of resolution of radiological images caused by patient motion is presented. Optical transfer functions (OTF) are computed for motion with uniform velocity and with simple harmonic oscillation. The line spread function (LSF) of a pattern of motion can be generated from the image of a long, narrow moving slit. Once the LSF is known the OTF of the motion can be obtained by Fourier transform.
本文提出了一种研究患者运动导致放射图像分辨率损失的方法。针对匀速运动和简谐振动计算光学传递函数（OTF）。运动模式的线扩展函数（LSF）可从狭长移动狭缝的图像生成。一旦知道了LSF，就可以通过傅里叶变换获得运动的OTF。
