Значения термина nonuniform attenuation на английском

The reconstructions modeled only the effects of nonuniform attenuation and used a range of subset configurations.

Also, Fourier-rebinning followed by OSEM with nonuniform attenuation correction exhibits less bias in ROI estimates than Feldkamp with Chang attenuation correction.

In regions of nonuniform attenuation, such as the thorax, it is possible that foci of increased tracer uptake disappear in images reconstructed without attenuation correction.
