【Abstract】 A transmission attenuation correction system of SPECT was valued with phantoms and in clinic. The results showed that transmission attenuation correction effectively cut down attenuation of γ ray caused by human body. It improves image contrast in deep location and accuracy of diagnosis finally.更多还原
