  • Title: [Comparison of scatter and attenuation correction methods in single photon emission CT--simulation study].
    Author: Ogawa K, Ono T, Shinohara H, Nishimura T.
    Journal: Kaku Igaku; 2000 Mar; 37(2):131-42. PubMed ID: 10783573.
    Abstract:
    Quantitative SPECT requires an accurate and appropriate attenuation correction and scatter correction. This paper compares scatter corrected images combined with attenuation correction. The scatter correction methods used here were the deconvolution method, dual energy window subtraction method, triple energy window method, and dual photopeak window method. The attenuation correction methods used were Sorenson's method, iterative Chang's method, and Bellini's method. The numerical phantoms used were the cold spot, hot spot, star, and MCAT phantom. These correction methods were assessed by using profiles and images, contrast values, and linearity of SPECT values.
