Abstract
The construction of a single ring positron emission tomograph with which to examine the brain is described. The ring comprises 160 bismuth germanate detectors that are not separated from each other by high Z septa. The thickness of the slice examined is 2 cm and the inherent resolution is 7 mm in the plane. The performance of the tomograph and representative clinical studies are illustrated.
摘要
本文描述了用于脑部检查的单环正电子发射断层扫描仪的构建。该环由160个锗酸铋探测器组成，它们之间没有被高原子序数的隔板隔开。所检查切片的厚度为2厘米，平面内的固有分辨率为7毫米。文中展示了该断层扫描仪的性能及代表性的临床研究。
