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 1. This section drafted in accordance with GB/T 1.1-2009 given rules. This Part replaces GB/T 18988.1-2003 "Part 1 Radionuclide imaging device - Characteristics and test. positron Radio tomographic imaging apparatus, "compared with the GB/T 18988.1-2003, the main technical changes are as follows. --- Increase the informative appendix NB, appendix uses a NEMA Standards Publication NU2-2007 "positron emission tomography Device performance test "; --- Increased introduction; NOTE contents of --- Figures 2 and 4 are moved to the text. This section uses the translation method is equivalent to using 61675-1 IEC .1998 Part 1 Radionuclide imaging device - Characteristics and test " Score. positron emission tomography apparatus "(in English).

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, this revision will NEMA Standards Publication NU2-2007 "positron emission tomography Performance means test "is incorporated in this section, as an information appendix NB. 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. Radionuclide imaging devices - Characteristics and test Part 1. Positron emission tomography apparatus1 General1.1 Scope and purpose GB/T 18988 provisions of this part of the terminology and test methods for positron emission tomography apparatus performance characteristics. Positron emission Tomographic imaging apparatus by coincidence detection method in detecting positron annihilation radiation-emitting radionuclides (annihilation radiation). Test methods specified in this part of the selection to reflect the positive clinical use as electron emission tomographic imaging apparatus. Performed by the manufacturer Test methods designed to enable them to explain positron emission tomography device characteristics. Therefore, the products were given in the technical file Article Member shall be consistent with this section. This standard does not specify which tests manufacturers will be on a single tomographic imaging apparatus. This section is no uniform method of measuring a predetermined image reconstruction, because most of all methods known to date are reflected in the image noise. 1.2 Normative references The following documents for the application of this document is essential. For dated references, only the dated version suitable for use herein Member. For cited documents without a date and its latest version (including any amendments) applies to this document. IEC 60788. 1984 Medical imaging academic language (MedicalRadiology-Terminology)2 Terms and definitionsIEC 60788. 1984 as defined in the following terms and definitions apply to this document. 2.1 Tomography tomography One or more layers within the body radiography. 2.1.1 Transverse Tomography transversetomography In the transverse tomography, a three-dimensional object by physical means (such as collimation) sliced \u200b\u200binto slices stacked objects, these sections may be considered It is two-dimensional, and independent. Transverse image plane perpendicular to the axis of the system. 2.1.2 Emission computed tomography emissioncomputedtomography; ECT An imaging technique (image forming method) of the two-dimensional tomographic slice through the object penetration radionuclides with the selected spatial distribution. 2.1.2.1 Projection projection To determine the physical characteristics of the image in the direction integral projection beam, so that a three-dimensional object is converted into two-dimensional image, or make a two-dimensional object Body is converted into one-dimensional image. NOTE. This process is described by the line integral digital projection made at the direction (along the lines of response) on a called Radon transform (Radon-transform). 2.1.2.2 The projection beam projectionbeam The projection beam determines the minimum possible volume imaging, this minimum volume, to determine the physical characteristics of the image in the measurement process is integrated. ...... |
