混合式PET/CT成像探测器
Abstract:
一种成像系统(102)包括：探测器阵列(104)，所述探测器阵列具有环(106)，所述环具有探测伽马辐射和X射线辐射的第一层(110i)和仅探测伽马辐射的第二层(110N)，其中，所述第一层和所述第二层是同心闭合环。一种方法包括：响应于在PET模式中进行成像而利用双层探测器的第一层来探测伽马辐射；响应于在PET模式中进行成像而利用所述双层探测器的第二层来探测伽马辐射；并且使用利用所述第一层和所述第二层探测到的辐射来生成PET图像数据。所述方法还包括响应于在CT模式中进行成像而利用所述第一层来探测X射线辐射；并且利用所述第一层探测到的辐射来生成CT图像数据。所述方法还包括显示所述图像数据。所述成像系统允许用于PET/CT成像两者的单一机架。
Abstract(English):

An imaging system (102) includes a detector array (104) with a ring (106) with a first layer (110i) that detects gamma radiation and X-ray radiation and a second layer (110N) that detects only gamma radiation, wherein the first and second layers are concentric closed rings. A method includes detecting gamma radiation with a first layer of a dual layer detector in response to imaging in PET mode, detecting gamma radiation with a second layer of the dual layer detector in response to imaging in PET mode, and generating PET image data with the radiation detected with the first and second layers.The method further includes detecting X-ray radiation with the first layer in response to imaging in CT mode and generating CT image data the radiation detected with the first layer. The method further includes displaying the image data. The imaging system allows a single gantry for both PET/CT imaging.
