Webcomparisons of using the LSF and ESF to calculate MTF as well as the use of super-resolution to overcome aliasing present in systems where the detector under-samples the optical system response [1]. In the current study, the point of interest is in making changes to how the Fourier transform is used to extract a MTF from the LSF. The methods WebThe spatial resolution of an x-ray or CT system is a measure of how the ability of a system to differentiate small structures. If you imagine imaging a very small point like object an image of that object is called the Point Spread Function (PSF). When this function is radially averaged the Line Spread Function (LSF) is generated.
