THE USE OF SOLID STATE DETECTORS FOR ORGAN COUNTING
Results of in-vivo measurement of a complex mixture of
gamma emitters with conventional whole body or organ counting
systems are often unsatisfactory because of the poor resolution
of the counting system. The possibility of eliminating this
problem by the use of a counting system employing a high resolu-
tion solid state detector prompted study of such a system to
determine its suitability in measuring amounts of radionuclides
in individual organs. The response of a dual crystal Ge(Li)
detector to gamma emitters contained in various organ compart-
ments of an anthropomorphic phantom was measured. The study
indicated that even though its sensitivity is poor relative
to that of conventional organ counting systems, use of a solid
state system may yield useful supplemental information for
assessment of internal depositions, provided the amount depos-
ited in the organ is sufficiently large, and that the back-
ground and counting geometry are controlled.
