摘要： A method for image reconstruction using projection data obtained by an asymmetric detector includes dividing the projection data into Regions 1, 2, 3, 4, and 5. Region 1 is an asymmetric region having detecting channels but no detecting channels symmetrical about a central channel. Region 2 is a transition region having detecting channels and there are detecting channels symmetrical about the central channel. Region 3 is a symmetric region having detecting channels and there are detecting channels symmetrical about the central channel. Region 4 is a transition region having detecting channels and there are detecting channels symmetrical about the central channel. Region 5 is a truncated region where there is no detecting channel. The method includes performing a view angle weighting on projection data in each of the five regions, and reconstructing a tomographic image of an irradiated subject from the weighted projection data.
摘要翻译：使用由非对称检测器获得的投影数据进行图像重建的方法包括将投影数据划分为1,2,3,4和5区。区域1是具有检测通道但不包括关于中心通道对称的检测通道的非对称区域。区域2是具有检测通道的过渡区域，并且存在关于中心通道对称的检测通道。区域3是具有检测通道的对称区域，并且存在关于中心通道对称的检测通道。区域4是具有检测通道的过渡区域，并且存在关于中心通道对称的检测通道。区域5是没有检测通道的截断区域。该方法包括对五个区域中的每个区域中的投影数据执行视角加权，以及从加权投影数据重构被照射的被摄体的断层图像。
