Calculate Modulation Transfer Function (MTF)



Formula

The formula to calculate the Modulation Transfer Function (MTF) is:

\[ \text{MTF} = \frac{\text{CI}}{\text{CT}} \]

What is Modulation Transfer Function?

The Modulation Transfer Function (MTF) is a measure of the imaging system's ability to reproduce (or transfer) contrast from the object to the image. It is used to quantify the image quality and sharpness. The higher the MTF value, the better the system is at preserving contrast and detail.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Modulation Transfer Function (MTF):

\[ \text{MTF} = \frac{\text{CI}}{\text{CT}} = \frac{0.8}{1.0} = 0.8 \]

The Modulation Transfer Function (MTF) is 0.8.
