16-detector
1.Diagnostic accuracy of noninvasive coronary imaging using 16-detector slice spiral computed tomography with 188 ms temporal resolution
2.Objective To evaluate the value and limit in display coronary disease with 16-detector row spiral CT.
3.Objective To study pelvicaliceal anatomy using three-dimensional images derived hy 16-slice multi-detector CT urography (CTU), and to discuss the role of CTU in planning for an optimal percutaneous approach into the pelvicaliceal system (PCS) prior to minimally invasive percutaneous nephrolithotomy (MPCNL).
5.High spin states of 80Rb have been studied by using fusion evaporation reactions, 65Cu+ 19F, 66Zn+ 18O and 68Zn+ 16O with beam energies of 75MeV, 76MeV and 80MeV, respectively, at HI-13 Tandem accelerator Beijing and JAERI Japan. γ-γ coincidence and DCO ratios were measured by the HPGe detector systems.
6.According to the emulating algorithm,TMS320C25 DSP is chosen to be the CPU of the detector. Other hardware units such as the 12-Bit A/Dconverter which works by semi-parallel mode with 7 KHz sampling rate,the 64k* 16-Bit EPROM,the 32k* 16-Bit RAM and the display using LCM are designed.
7.The volume of the Ge(Li)detector was 78cm~3.For γ-ray of the energy of 1332keV of ~(60)Co,the resolution of thespectrometer was about 2.4keV,the ratio of the peak to compton was 6.4without shielding,the relative efficiency was 16%,and for the γ-ray peakof ~(137)Cs the detective efficiency was 1.6%.
