Experimental Evaluation of a Tellurium-123m Transmission Source to Determine Attenuation Maps for SPECT1


Journal Article

We propose to use a tellurium-123m line source to determine attenuation maps for reconstruction of technetium-99m images. To experimentally evaluate the performance of the transmission line source for the fast sequential approach for emission and transmission data acquisition, a prototype tellurium-123m line source was designed and manufactured. The line source has a length of 8 cm with total activity of 36–39 mCi at the time of the studies. Phantom and patient studies were conducted to evaluate the performance of the line source. The results of this study demonstrate that the tellurium-123m line source can be used to accurately determine attenuation maps for transmission studies with Tc-99m activity in the patient's myocardium. © 1995 IEEE.
