How do you calculate modulation transfer function?
The MTF, or Modulation Transfer Function, is defined as the ratio of the image contrast to the target contrast, expressed as a function of spatial frequency. That is, MTF(u) = C'(u) / C(u). C is the contrast in the target, C' is the corresponding contrast in the image.
What is modulation transfer function in image processing?
The modulation transfer function (MTF) is a graphical description of the spatial resolution characteristics of an imaging system or its individual components. It is generally useful for separating individual causes of image degradation. Another related term is the contrast transfer function (CTF).
What is MTF in image processing?
The modulation transfer function, or MTF, is a parameter used to evaluate the performance of a lens. MTF provides a quantitative and standardized way to characterize optical systems, so the metric is used by optical designers and microscopists alike to compare lenses and determine the ideal one for an imaging system.
What does MTF measure in radiology?
Modulation Transfer Function
The MTF measures the amplitude (ie. signal brightness) change of different spatial frequencies as they pass through the imaging system. We can make an analogy to the resolution bars, higher spatial frequencies correspond to more bars (i.e. more line pairs) in the same distance.
