摆线计算机断层扫描结合了横向样本的平移和旋转，是一种完全与飞行扫描兼容的采集方案，用于使用幅度调制光束的微型计算机断层扫描系统。这样的系统已经得到普及，因为它们能够实现x射线相衬成像 (XPCI) 和孔径驱动的空间分辨率。前者为弱衰减的样品提供了优异的对比度，而后者允许微计算机断层摄影系统的分辨率增加到由源和检测器规定的常规极限之外。这种系统最初需要时间效率低下的步进拍摄采集，这一限制已被摆线计算机断层扫描的发展所消除。在这里，我们得出了在nyquist-shannon定理意义上最佳的摆线采样条件。它们的可用性使得能够以时间高效的方式采集良好采样 (即高分辨率) 的XPCI图像，这是与实验室实施相关的长期寻求的结果，其中扫描时间传统上很长，以及同步加速器实施，其中下一个前沿是实现高速 (例如，动态) 成像。我们不对所使用的x射线源的类型进行任何假设，而是演示了旋转阳极x射线管的最佳条件。
