HDCT and Its Clinical Application / 医疗卫生装备

ABSTRACT

The number of detector rows has been the focus of the CT development for decades.During the last decade,CT development has reached a threshold which is represented by coverage,mechanics,resolution and dosage.In order to break this bottleneck,two further development directions have been shown in recent years,of which,one is to increase the number of the detector rows,and the other is to revolutionize the material of detector to explore new clinical applications.Generally,HDCT opens the new era for whole CT modality,bringing the radiologists the high-resolution image,spectral imaging,large coverage and low dosage application.
