Summary:An imaging system is provided that includes a gantry, a plurality of image detectors, an x-ray source, an adjustable source collimator, and at least one processor. The image detectors are radially spaced around a circumference of the bore such that gaps exist between adjacent image detectors. The x-ray source transmits x-rays across the bore towards at least two of the image detectors. The adjustable source collimator is interposed between the x-ray source and a center of the bore, and is configured to block a portion of the x-rays produced by the x-ray source. The at least one processor is configured to control the adjustable source collimator to dynamically adjust a range of x-rays that are blocked by the adjustable source collimator along the fan angle during transmission of x-rays fromthe x-ray source and acquisition of computed tomography (CT) information. 提供种成像系统，其包含台架、多个图像检测器、x射线源、可调整源准直器和至少个处理器。图像检测器围绕膛的圆周径向间隔，使得间隙存在于相邻的图像检测器之间。x射线源跨膛朝图像检测器的至少两个传送x射线。可调整源准直器置于x射线源和膛中心之间，并且配置成阻挡由x射线源产生的x射线的部分。至少个处理器配置成
