自1985年以来，由一对多丝正比室组成的正电子照相机已在伯明翰用于涉及正电子发射放射性示踪剂的工程研究。伯明翰开发的正电子发射粒子跟踪技术（PEPT），可以高速跟踪单个示踪粒子，已被证明是特别强大的。最初的正电子照相机的主要限制是它的低灵敏度和相应的低数据率。最近安装了一台新的正电子照相机：它由一对NaI（T1）伽马照相机头组成，具有全数字读数，在数据速率和数据质量方面有了巨大的改进。该相机的性能，特别是它带来的PEPT技术的改进能力，进行了总结。(C)2002 Elsevier Science B.V.保留所有权利。
Since 1985 a positron camera consisting of a pair of multi-wire proportional chamber, has been used at Birmingham for engineering studies involving positron emitting radioactive tracers. The technique of positron emission particle tracking (PEPT), developed at Birmingham, whereby a single tracer particle can be tracked at high speed, has proved particularly powerful. The main limitation of the original positron camera was its low sensitivity and correspondingly low data rate. A new positron camera has recently been installed: it consists of a pair of NaI (T1) gamma camera heads with fully digital readout and offers an enormous improvement in data rate and data quality. The performance of this camera, and in particular the improved capabilities it brings to the PEPT technique, are summarised. (C) 2002 Elsevier Science B.V. All rights reserved.
