A system for continuous production and infusion of [15O]H2O has been designed for Positron Emission Tomography brain activation studies. The infusion system consists of two Horizon Nxt infusion pumps, a four-port-two-position valve and a sterile 50 ml vial. The line and the back check valve between the furnace and the reservoir were heated in order to reduce vapor condensation in the line. The variation of the production of [15O]H2O was < 1%. The activity delivered as measured by scanner counts varied < 2% during the steady state period. The system has been demonstrated to be capable of delivering activity over a wide range of conditions.
一种用于正电子发射断层扫描脑激活研究的[15O]H2O连续生产和输注系统已被设计出来。该输注系统由两个Horizon Nxt输注泵、一个四通二位阀和一个无菌50毫升小瓶组成。为了减少管路中的蒸汽凝结，炉与储液器之间的管路和止回阀被加热。[15O]H2O的产量变化<1%。在稳态期间，通过扫描仪计数测量的输送活度变化<2%。该系统已被证明能够在广泛的条件下输送活度。
