    How to determine the response function of an imaging system?

    I'm trying to solve the following problem: If I had an imaging system in a black box, how could I derive its response function? My first idea was to use a plane wave, and measure the output. I know that the convolution of the input wave with the response function gives us the output. As we...

    SNR in X-ray imaging

    The problem statement, all variables and given/known data (1) An ideal digital detector only suffers from quantum noise. If, after being exposed to 5 µGy the mean pixel value in the image is 100 and the standard deviation of the pixel values in the image is 5, calculate the SNR? The...
