目的探讨研究核医学SPECT/CT成像的质量控制的措施。方法以德国西门子Symbia T6型SPECT/CT为例,从SPECT图像的质量控制、CT图像的质量控制、图像融合测试3个方面分析SPECT/CT的图像质量控制。结果质量控制的指标是否合格决定图像的可信度、准确性。结论做到定期的SPECT/CT的质量控制,可延长仪器的寿命,提高图像的可信度和准确度。
Objective To investigate the quality control of nuclear medicine SPECT / CT imaging. Methods Taking the German Siemens Symbia T6 SPECT / CT as an example, the image quality control of SPECT / CT was analyzed from three aspects of SPECT image quality control, CT image quality control and image fusion test. The result of the quality control of the indicators is qualified to determine the credibility of the image, accuracy. Conclusion Regular SPECT / CT quality control can prolong the life of the instrument and improve the reliability and accuracy of the image.
