塑料闪烁体探测系统已被开发用于测量动脉血H2 15 O浓度的正电子发射断层扫描（PET）局部脑血流（lCBF）的研究。该系统使用蠕动泵从桡动脉连续抽取动脉血，通过塑料闪烁体检测氧-15正电子。为了纠正由于泵管中的层流而导致的动脉血液曲线形状的涂抹，开发了一种去卷积技术。
A plastic scintillator detection system has been developed for the measurement of arterial blood H2 15O concentrations in positron emission tomographic (PET) local cerebral blood flow (lCBF) studies. The system uses a peristaltic pump to continually pull arterial blood from a radial artery through the plastic scintillator for the detection of the oxygen-15 positrons. To correct for the smearing of the arterial blood curve shape due to laminar flow in the pump tubing, a deconvolution technique has been developed.
