摘要

PET是Positron Emission Tomography的缩写，汉语名称为正电子发射计算机断层仪。PET与CT结合在一起，即组成了目前医学影像中超高档的产品PET/CT。

PET是利用放射性核素示踪剂，无创伤地进行显像以反映脏器的功能，血流和代谢变化。我国生产的正电子发射型计算机断层扫描仪的机架的结构简陋，强度始终不高，虽然经过几十年的发展，近期产品的质量较早期有所提高。但受国产配套件质量及设计水平等的影响，我国目前生产的正电子发射型计算机断层扫描仪的机架的总体水平与进口产品及港口用户的要求仍有较大差距，正电子发射型计算机断层扫描仪的机架的生产也是如此，为满足市场需求，开发出一种新型的正电子发射型计算机断层扫描仪的机架系统势在必行！

相信此种正电子发射型计算机断层扫描仪的机架系统的出现将会大大提高正电子发射型计算机断层扫描仪的质量和寿命，为患者提供更高的舒适度，为医疗机械的发展带来显著的进步，同时也在某种程度上推进了医疗机械工业的不断发展。

PET is the abbreviation of Emission Tomography Positron, Chinese name is a positron emission computed tomography. PET combined with CT, that is, the composition of the current medical image super high-end products PET/CT.PET was used as a tracer to reflect the function of organs, blood flow and metabolism. The structure of the frame of the positron emission computed tomography scanner in our country is simple, the strength is not high, although after several decades of development, the quality of the products has improved in recent years. But affected by supporting domestic product quality and design level, China's current production of positron emission computed tomography of the frame of the overall level and product import and port users still have a large gap, positron emission computed tomography frame production, too, in order to meet the market demand, developed a new type of positron emission computed tomography scanner rack system is imperative!

Believe this positron emission computed tomography of the rack system will greatly improve the positron emission computed tomography and quality of life, to provide greater patient comfort, and make significant progress for the deve
