Investigation of Attenuation Correction for Small-Animal Single Photon Emission Computed Tomography
The quantitative accuracy of SPECT is limited by photon attenuation and scatter effect when photons interact with atoms. In this study, we developed a new attenuation correction (AC) method, CT-based mean attenuation correction (CTMAC) method, and compared it with various methods that were often use...
