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.
