Investigation on Technical Principle and Clinical Application of Dual-Source CT / 医疗卫生装备

The structure and working principle of dual-source CT(DSCT) and its clinic application are expatiated.Many advantages are proved after the analysis and discussion and also after the validation of clinic application,such as higher temporal resolution for the imaging of cardiac and coronary artery to be finished without the influence of any heart rate,lower X-ray absorbing dose to offer more safe surrounding for the patients,higher special resolution and higher signal to noise of images to offer more reliable diagnostic tool,the technology of dual-energy is special in the examination and research of function and metabolize of human being.
