“…There are two advantages in the use of this 2D array as a portal dose device for the IMRT quality assurance program: first is the ability to perform absolute dose comparisons for hundreds of measurement positions to verify the correct dose delivery in several fractions of the therapy; second is the efficiency in time to detect these kinds of dose distributions within the field of view area of the CT scanner. …”

“…The aim of this study was to analyze the characteristics of pregnancy and delivery before and after the implementation of the two-child policy to make suggestions on the quality assurance of the new era of obstetrics. METHODS: In total, 5895 cases of pregnant women who delivered from April 2016 to March 2017 in Peking University Third Hospital served as the study group and 5103 cases of pregnant women who delivered from January to December 2015 served as the control group. …”
