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 is the MTF contrast equation?
A higher MTF value indicates better image quality and resolution. It is analogous to a high-resolution TV versus a pixelated low-resolution screen. The MTF is the ratio of relative image contrast divided by relative object contrast: Modulation transfer function = relative image contrast/relative object contrast.
What does MTF mean sensor?
CMOS image sensors are widely used on digital imaging devices. The modulation transfer function (MTF) of the image sensors is an important characteristic to evaluate the overall imaging system quality. The image sensor MTF reflects the spatial frequency response of the sensor.
