Motion phase-dependent PET attenuation maps. The attenuation map in the reference motion phase was transformed to end-inspiration/end-systole using the estimated motion fields. The resulting attenuation map is similar to the true attenuation map for end-inspiration/end-systole obtained directly from XCAT. a Reference motion phase (end-diastole/end-exhalation) b Transformed from the reference phase to end-inspiration/end-systole c End-inspiration/end-systole (directlyu form XCAT)
