  • Dual isotope scintigraphic image enhancement
    Patent number: 4846187
    Abstract: An improved method of dual isotope subtraction scintigraphic image processing uses a band pass spatial frequency filter to smooth and enhance the image obtained with the less well resolved isotope and then applies the same filter function to the image from the better resolved isotope, after which the images are subtracted to produce an enhanced image with reduced edge artifacts and better resolution. The method can be applied to images where the target/background ratio approaches unity, and to single isotope imaging.
