Quantitative evaluation of simultaneous reconstruction with model‐based crosstalk compensation for dual‐isotope simultaneous acquisition brain SPECT
Abstract
A model-based method has been previously developed to estimate and compensate for the crosstalk and downscatter contamination in simultaneous 123I/99mTc dual-isotope SPECT imaging. In this method, photon scatter in the object is modeled using the effective source scatter estimate technique. Photon interactions with the collimator-detector are estimated using precalculated Monte Carlo simulated point response functions. Two different approaches, …
