It reports effects of changes in the thickness of the employed Lutetium Oxyorthosilicate(LSO) detectors. The PET/CT, a human body phantom and a cylindrical F-18 FDG source were simulated. Validation measurements were conducted. The results indicate that LSO thickness increase degrades spatial resolution, improves relative energy resolution from 9.0% to 11.3% and increases signal-to-noise-ratio from 0.81 to 1.17. Thicker LSO crystals present greater axial sensitivity so as the detection efficiency of PET would be significantly enhanced.展开更多

It was on May 29, 1959, when the late Premier Zhou Enlai came to visit Dr. Yu’s laboratory during his inspection tour at the Tianjin University. This has been an unforgettable event in Prof. Yu’s mind. When shaking hands with Prof. Yu, Premier Zhou said: "I heard that you have made great advances in the rescarch of heavy water. I am eagerly waiting for further success in your work. For the honor of our country, we must have heavy water developed with our own hands, in defiance of someone who attempts to strangle us." Looking into the Premier’s eyes of encouragement,Prof. Yu was then determined to live up to the expectations of the motherland by making a good job of his research work.展开更多
