讨论了调制传递函数 (MTF) 测量中使用的调节数据的方法。该方法基于施加边缘扩展函数 (ESF) 单调的约束。当适用时，该技术的优点可以通过已知真实 MTF 的模拟示例来证明。还演示了该技术在临床使用的数字探测器 MTF 测量中的应用。 (C) 2003 年美国医学物理学家协会。
A method for conditioning data used in the measurement of the modulation transfer function (MTF) is discussed. This method is based upon imposing the constraint that the edge spread function (ESF) is monotonic. The advantages of this technique, when applicable, are demonstrated with simulated examples for which the true MTF is known. The application of this technique in the measurement of the MTF of a digital detector in clinical use is also demonstrated. (C) 2003 American Association of Physicists in Medicine.
