In spite of the fact that many gamma-emitting nuclides have more than one useful gamma energy. it is impossible in imaging with the conventional scintiscanner system to include more than one photopeak within the window, unless the two peaks are very close together. The dual-spectrometer system. we describe here. requires the addition of a second summing network and pulse-height analyzer to the standard Toshiba scintiscannner. In the case of ^<67>Ga, detection efficiency has been increased 30%-50% without degrading resolution by using the dual-spectrometer system.
