据新华网4月7日消息报道,全数字PET成像关键技术5日通过中国工程院士俞梦孙领衔的专家组鉴定,认为达到国际领先水平。中国科学家在PET数字化领域的技术突破,意味着可更早、更灵敏地发现肿瘤,诊断癌症,为人类造福。诞生于上世纪70年代的PET(正电子发射断层成像仪)是继超声、CT和核磁共振之后当今先进医学影像技术之一,已成为临床早期诊断和指导癌症治疗的最佳手段之一。但因超高速闪烁脉冲信号难以数字化技术的影响,PET难以实现全数字化,至今只有模拟和模拟数字混合型机器。针对这一世
Xinhua News Agency, April 7, according to Xinhua News reports, all-digital PET imaging key technology on the 5th by the Chinese Academy of Engineering Yu Mengsun led by the expert group identified that reached the international advanced level. Chinese scientists in the field of digital PET technology breakthrough, means that earlier, more sensitive to detect cancer, cancer diagnosis, for the benefit of mankind. PET (Positron Emission Tomography), which was born in 1970s, is one of the most advanced medical imaging techniques after ultrasound, CT and MRI. It has become one of the best methods for early diagnosis and guidance of cancer treatment. However, due to the hard-to-digitize technology of ultra-fast flashing pulse signals, PET is difficult to achieve full digitalization. So far, only analog and analog digital hybrid machines have been adopted. Against this world
