摘要:
We have examined several whole body counting geometries for exclusive use in total body potassium (TBK) measurements is in preterm infants. This paper describes two counters, one for very-low-birth-weight (VLBW) infants with body weights under 2000 g, and a second counter for larger preterm infants. Both systems use large-volume NaI(Tl) detectors (10.2 cm x 10.2 cm x 45.7 cm) and are operated in a low background room. The standard error for a TBK measurement decreases from 5% at 1 kg body weight to 2% at 4.5 kg weight.
