A two\u2010dimensional point spread function (2D\u2010PSF) was estimated in the image domain to model the combination of these two physical effects. This 2D\u2010PSF in the inhomogeneous medium is fitted with an asymmetric Gaussian function based on Monte Carlo simulation results. An efficient further blurring and deconvolution method was used to restore images from the spatially variant 2D\u2010PSF kernel. The compensation is performed using a computer\u2010simulated NCAT phantom and a flanged Jaszczak experimental phantom. The preliminary results demonstrate an improvement in image quality and quantity accuracy with increased image contrast (25% increase compared to uncompensated image) and decreased error (40% decrease compared to uncompensated image). This method also offers an alternative to compensate for scatter and blurring in a more time efficient manner compared to the popular iterative methods. The execution time for this efficient postprocessing method is only a few minutes, which is within the clinically acceptable range.<\/jats:p>","DOI":"10.1155\/2008\/806705","type":"journal-article","created":{"date-parts":[[2009,3,8]],"date-time":"2009-03-08T13:59:19Z","timestamp":1236520759000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Scatter and Blurring Compensation in Inhomogeneous Media Using a Postprocessing Method"],"prefix":"10.1155","volume":"2008","author":[{"given":"Yan","family":"Yan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gengsheng L.","family":"Zeng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2009,3,4]]},"reference":[{"key":"e_1_2_7_1_2","doi-asserted-by":"publisher","DOI":"10.1109\/TMI.2002.803130"},{"key":"e_1_2_7_2_2","first-page":"432","article-title":"Optimum compensation method and filter cutoff frequency in myocardial SPECT: a human observer study","volume":"43","author":"Sankaran S.","year":"2002","journal-title":"Journal of Nuclear Medicine"},{"key":"e_1_2_7_3_2","first-page":"1725","article-title":"Human-observer receiver-operating-characteristic evaluation of attenuation, scatter, and resolution compensation strategies for \u200999mTC myocardial perfusion imaging","volume":"44","author":"Narayanan M.
