Abstract

Specifies terminology and test methods for declaring the characteristics of Anger type rotational gamma camera single photon emission computed tomographs. This Standard is identical with and has been reproduced from IEC 61675-2:1998.

Scope

This part of IEC 61675 specifies terminology and test methods for describing the characteristics of
Anger type rotational GAMMA CAMERA SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHS (SPECT),
equipped with parallel hole collimators. As these systems are based on Anger type GAMMA CAMERAS this part of IEC 61675 shall be used in conjunction with IEC 60789. These systems consist of a gantry system, single or multiple DETECTOR HEADS and a computer system together with acquisition, recording, and display devices.
The test methods specified in this part of IEC 61675 have been selected to reflect as much as possible the clinical use of Anger type rotational GAMMA CAMERA SINGLE PHOTON EMISSION COMPUTED TOMOGRAPHS (SPECT). It is intended that the test methods be carried out by manufacturers thereby enabling them to describe the characteristics of SPECT systems on a common basis.
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.
