Original title: world's first clinical whole body full digital PET equipment successfully developed in Wuhan

Jing-Chu network news (Xinhua correspondent Wang xiaoxiao in the spring on Wednesday) "clinical whole body ' digital PET' was available, a series of major diseases such as cancer can be earlier, more accurate detection, decision. "Wuhan national laboratory for Optoelectronics (chip) researcher, said Xie Qingguo, a Professor of Huazhong technological University. On April 27, announced Xie Qingguo and led the team in Wuhan, has successfully developed the world's first digital PET equipment could be used in the body check. Accuracy is improved at the same time, Taiwan is expected to further reduce the cost of PET examination.

It is understood that Positron Emission Tomography Imaging (English abbreviation PET) is the second ultrasound, CT and MRI after today's top medical imaging technology. In terms of disease diagnosis and its image accuracy is far better than the first two. Can be found earlier and more sensitive to cancer and other diseases, and diagnosis of cancer, for the benefit of mankind.

But due to the ultra high speed flashing pulse signals to digital technology, PET is difficult to achieve fully digital, over a long period of only analog and analog-digital hybrid machines.

Since 2001, Xie Qingguo leads a team dedicated to digital and precise measurement of "digital PET" research. In 2013, the team that developed the digital PET detector and the world's first digital PET machines, and successfully applied to small animals on the test.

According to reports, the development of the first clinical whole body "full digital PET" over more than 300 digital PET detection modules, each detection module uses advanced scintillation crystals and novel photomultiplier device. Also thanks to the full digital sampling and signal processing algorithms, which has reached 2.2 mm spatial resolution than the current highest level almost 1 time times the import equipment. "The tumor the size of a sesame seed to be accurately detected, check for longer than traditional PET checks also cut in half. "Xie Qingguo said.

Previously, only Siemens, General Electric, Philips and other independent development and production of PET imaging. Xie Qingguo said currently he and his team of digital PET, all performance indicators are better than the industry standard. At present, the equipment will soon be in Peking Union Medical College Hospital and clinical trials on people's Hospital of Wuhan University, respectively.

It is understood that the current domestic PET examination costs tens of thousands Yuan. Clinical trial of domestic digital PET, once adopted, to obtain the relevant approval to market, would greatly reduce the cost of domestic PET equipment and testing costs. This will give a strong impetus for the early detection of cancer PET examination to the universal development.

　　原标题：全球首台临床全身全数字PET设备在武汉研制成功

　　荆楚网消息（记者周三春 通讯员王潇潇）“临床全身‘全数字PET’问世后，能让癌症等一系列重大疾病得到更早、更精确的检测、判定。”武汉光电国家实验室（筹）研究员、华中科技大学教授谢庆国表示。4月27日，谢庆国和所带领团队在武汉宣布，已成功研制出全球首台可用于临床全身检查的全数字PET设备。在检测精度提高的同时，国人PET检查的成本有望进一步降低。

　　据了解，正电子发射断层成像仪（英文缩写PET）是继超声、CT和核磁共振之后当今最顶尖的医学影像技术。在疾病诊断方面，其成像精度要远优于前两种。可更早更灵敏地发现肿瘤等疾病病灶，诊断癌症，为人类造福。

　　但因超高速闪烁脉冲信号难以数字化的技术瓶颈，PET难以实现全数字化，在较长时内只有模拟和模拟数字混合型机器。

　　2001年以来，谢庆国带领团队致力于全数字化和精准测量的“全数字PET”研究。在2013年团队即研制出了全数字化PET探测器及世界首台小型数字PET机器，并成功应用于小动物的试验上。

　　据介绍，此次研制的首台临床全身“全数字PET”由300多个全数字PET探测模块组成，每个探测模块均使用先进的闪烁晶体及新型光电倍增器件。同时借助全数字采样和信号处理算法，其空间分辨率已达到2.2毫米，比当前进口设备的最高水平提升近一倍。“一粒芝麻大小的肿瘤病灶都能精确检测出来，检查时间比传统PET检查也要减少一半。”谢庆国说。

　　此前，全球仅有西门子、通用电气、飞利浦等能独立研制和生产PET成像设备。谢庆国表示，当前他和团队研发的全数字PET，在所有检测性能指标上均好于业内水平。目前，这一设备即将在协和医院与武汉大学人民医院分别进行临床试验。

　　据了解，当前国内PET检查费用动辄过万元。国产全数字PET一旦通过临床试验，获得相关批文走向市场，将大大降低国内PET设备的造价及检测成本。这将极大地推动面向癌症早期检测的PET检查向普及化发展。
