Abstract

A high purity germanium gamma-camera has been developed and is currently being evaluated. This camera incorporates unique performance parameters such as a 2 mm full-width spatial response function with rejection of multiple-scatter in the detector, a 2.2% FWHM energy resolution for 99 mTc, a 180 nsec paralyzable dead-time, and a 2 mu sec non-paralyzable dead-time. Imaging studies demonstrate the superior capabilities of this instrument.

摘要

一种高纯度锗γ相机已被研制出来，目前正在进行评估。该相机具有独特的性能参数，如2毫米全宽空间响应函数且能抑制探测器中的多次散射、对于99mTc的半高宽能量分辨率为2.2%、180纳秒可瘫痪死时间以及2微秒不可瘫痪死时间。成像研究证明了该仪器的卓越性能。
