Effect of cut-off frequency of butterworth filter on detectability and contrast of hot and cold regions in Tc-99m SPECT

In SPECT, noise is one of the major limitations that degrade image quality. To suppress the noisy signals in an image, digital filters are most commonly applied. However, in SPECT image recon-struction, selection of an appropriate filter and its functions has always remained a difficult task. In thi...
