What is the equation for MTF?
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 does MTF stand for XRAY?
The modulation transfer function (MTF) is the most widely accepted measure of the spatial resolution response of medical x-ray imaging detectors and has proved to be a valuable tool for determining and comparing detector performance.
What does MTF mean sensor?
The Modulation Transfer Function (MTF) describes how well a camera can represent the detail contrast of an object in the image. The MTF is measured by, for example, recording a line grid with the camera. The brightness distribution of such a grid corresponds to a sinusoidal curve.
What is the MTF of the imaging system?
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.
