IEC TR 61948-2:20 19适用于平面闪烁照相术和断层照相术中使用的带有平行孔准直器的单光子闪烁相机。它也适用于具有平行孔准直器的SPECT/CT系统的SPECT部分，包括SPECT和CT子系统之间的共同配准。目的是规定质量控制的常规测试。IEC 61675-2中描述了验收测试的方法。 IEC TR 61948-2:20 19取消并取代2001年发布的第一版。它构成技术修订。 与上一版相比，此版本包括以下重大技术变更: a)适于应用于本技术； b)更新测试方法以符合最新技术水平。

IEC TR 61948-2:2019 is valid for single photon scintillation cameras with parallel hole collimators used in planar scintigraphy and tomography. It is also valid for the SPECT portion of SPECT/CT systems with parallel hole collimators, including the co-registration between the SPECT and CT subsystems. The objective is to specify ROUTINE TESTS for QUALITY CONTROL. Methods for the ACCEPTANCE TEST are described in IEC 61675-2.
IEC TR 61948-2:2019 cancels and replaces the first edition published in 2001. It constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) adaptation to apply to the present technology;
b) updating of the test methods to comply with the recent state of the art.
