1.1 Scope and Purpose This part of GB/T 18988 specifies the terminology and test methods for the performance characteristics of positron emission tomography devices. The positron emission tomography device detects the annihilation radiation (annihilation radiation) of positron emitting radioactive nuclides through the coincidence detection method. Select the experimental methods specified in this section to reflect the clinical use of positron emission tomography devices as much as possible. The test method performed by the manufacturer aims to enable them to demonstrate the characteristics of positron emission tomography devices. Therefore, the technical conditions provided in the product random documents should comply with this section. This section does not specify which tests the manufacturer will conduct on a single tomographic imaging device. This section does not specify a measurement method for the uniformity of reconstructed images, as most of the known methods so far reflect the noise in the image. 1.2 Normative References The following documents are essential for the application of this document.
