Foreword

GB/T 18988 "Radionuclide imaging device - Characteristics and test" is divided into three parts.

--- Part 1. Positron emission tomography apparatus;

--- Part 2. Single photon emission computed tomography apparatus;

--- Part 3. Gamma camera body imaging system.

This section GB/T 18988 Part 3.

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This Part replaces GB/T 18988.3-2003 "Part 3 Radionuclide imaging device - Characteristics and test. Gamma camera Machine body imaging system, "compared with the GB/T 18983.3-2003, the main technical changes are as follows.

--- Increase the informative appendix C, appendix uses a NEMA Standards Publication NU1-2007 "Gamma Camera Performance Test" Chapter 5 of the first content;

--- Increased introduction.

This section uses redrafted law revision using IEC 61675-3:1998 "Radionuclide imaging device - Characteristics and test rule Part 3. Gamma camera imaging system of the body, "according to the standard rules of the preparation of this section do the following editorial changes. an increase of capital Material Appendix B.

This section remains GB/T 18988.3-2003 modify using IEC 61675-3:1998; this portion of the IEC 61675-3:1998's Reg number control See Appendix A; this section with IEC 61675-2:1998 technical differences between their causes, see Appendix B.

Please note that some of the content of this document may involve patents. Release mechanism of the present document does not assume responsibility for the identification of these patents.

This part is proposed by the State Food and Drug Administration.

This part of the National Standardization Technical Committee on Medical Electrical radiotherapy, nuclear medicine and radiation dosimetry equipment Standardization Technical Committee Will (SAC/TC10/SC3) centralized.

Introduction

GB/T 18988.3-2003 modify using IEC 61675-3:1998. Currently, the major manufacturers of raw radionuclide imaging apparatus Production sites are located in the United States, the parameters of its report, the data processing software, test phantoms are standard NEMA National Electrical Manufacturers Association as the design basis, but also manufacturers use IEC standard. In order to facilitate the government, enterprises and medical institutions understand and use of such products IEC and NEMA content of two series of standards, the changes made in the NEMA Standards Publication NU1-2007 "gamma camera performance measurement Again. "Chapter 5 are introduced in this section, as an information appendix C.

Since the IEC and NEMA standards there are some differences in testing requirements, test methods, the use of motifs, test conditions, test Position, the calculation method is different, so I can not compare with each other between the two standard test items and complete references recommend two standard user the method of any one species, not cross-use.
