    • The present disclosure discloses a detector device comprising a plurality of detector assemblies. Each detector assembly comprises at least one detection crystal units having a first energy response and those having a second energy response, which are both arranged along a first direction at intervals, each detection crystal unit having a first/second energy response including at least one detection crystals having a first/second energy response arranged along a second direction. The at least one detection crystal units having a first energy response and the at least one detection crystal units having a second energy response are, at least partially, alternatively arranged along the first direction when viewed from an incidence direction of the X-ray. The present disclosure also discloses a dual energy CT system having the detector device and a CT detection method using this system.
    • 本公开公开了一种包括多个检测器组件的检测器装置。 每个检测器组件包括具有第一能量响应的至少一个检测晶体单元和具有第二能量响应的检测晶体单元,它们都沿着第一方向间隔排列,每个检测晶体单元具有包括至少一个检测的第一/第二能量响应 具有沿第二方向布置的第一/第二能量响应的晶体。 当从X射线的入射方向观察时,具有第一能量响应的至少一个检测晶体单元和具有第二能量响应的至少一个检测晶体单元至少部分地沿第一方向布置。 本公开还公开了一种具有检测器装置和使用该系统的CT检测方法的双能CT系统。
