Optimized acquisition time and image sampling for dynamic SPECT of Tl-201
IEEE Transactions on Medical Imaging（1998）
摘要
With the recent development in scatter and attenuation correction algorithms, dynamic single photon emission computerized tomography (SPECT) can potentially yield physiological parameters, with tracers exhibiting suitable kinetics such as thallium-201 (Tl-201). A systematic way is proposed to investigate the minimum data acquisition times and sampling requirements for estimating physiological para...
