BS EN 61675-2:2015规定了描述特性的术语和试验方法 用于平面成像的配备平行孔准直器的伽马相机。 对于能够进行平面整体测量的伽马相机，规定了附加测试 成像（平面全身成像设备）或计算单光子发射 断层扫描（SPECT）。这些伽马相机由机架、单个或多个探测器组成 以及一台用于数据采集、处理、存储和显示的计算机。探测器 磁头可以包含单个或多个闪烁晶体或固态探测器。 目前还没有规定对重建图像的均匀性进行测试，因为 目前已知的方法大多反映图像的噪声。交叉引用:IEC/TR 60788:2004IEC 61675-1:2013EN 61675-1:2014取代了BS EN 61675-2:1998、BS EN 61675-3:1998和BS EN 60789:2005，它们仍然是最新版本。购买本文件时，所有当前可用的修订都包括在购买本文件中。

BS EN 61675-2:2015 specifies terminology and test methods for describing the characteristics of GAMMA CAMERAS equipped with PARALLEL HOLE COLLIMATORS for planar imaging. Additional tests are specified for those GAMMA CAMERAS that are capable of planar wholebody imaging (PLANAR WHOLEBODY IMAGING EQUIPMENT) or SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHY (SPECT). These GAMMA CAMERAS consist of a gantry, single or multiple DETECTOR HEADS, and a computer for data acquisition, processing, storage, and display. The DETECTOR HEADS may contain single or multiple scintillation crystals or solid state detectors.No test has been specified to characterize the uniformity of reconstructed images because all methods known so far will mostly reflect the noise of the image.Cross References:IEC/TR 60788:2004IEC 61675-1:2013EN 61675-1:2014Replaces BS EN 61675-2:1998, BS EN 61675-3:1998 and BS EN 60789:2005 which remain currentAll current amendments available at time of purchase are included with the purchase of this document.
