在X射线微CT应用中,通过偏移二维(2D)探测器阵列来增加视场是有用的。在本技术说明中,我们简要回顾了使用非对称2D探测器阵列进行图像重建的方法,详细说明了在螺旋/螺旋锥束扫描情况下使用相关加权方案,并进行了一系列数值测试,以证明使用这种布置进行螺旋锥束图像重建。
In x‐ray micro‐CT applications, it is useful to increase the field of view by offsetting a two‐dimensional (2D) detector array. In this technical note, we briefly review the methods for image reconstruction with an asymmetric 2D detector array, elaborate on the use of an associated weighting scheme in the case of helical/spiral cone‐beam scanning, and perform a series of numerical tests to demonstrate helical cone‐beam image reconstruction with such an arrangement.
